How We Chose
We compared 11 Amazon drives across PCIe 5.0, PCIe 4.0, SATA, and portable categories. The shortlist weighs owner ratings, review counts, real-world speed claims, warranty length, and whether a drive is widely listed as Prime-eligible. Data was checked in October 2026. Pricing fluctuates through the event, so every recommendation here is based on the drive’s standing in the market, not a one-day sticker.
1. Sandisk Extreme 2TB Portable: Editor’s Choice
Sandisk 2TB Extreme Portable SSD, Up to 1050MB/s, USB-C, USB 3.2 Gen 2, IP65 Water and Dust Resistance, Updated Firmware, External Solid State Drive, SDSSDE61-2T00-G25
Capacity: 2TB
Interface: USB 3.2 Gen 2
Speed: 1050 MB/s
Durability: IP65 3m drop
Pros
- Up to 1050 MB/s read and 1000 MB/s write over USB-C
- IP65 water and dust resistance with 3 meter drop protection
- 256-bit AES hardware encryption and password protection
- Carabiner loop for travel and a compact 1.76 ounce body
- Bestseller rank #1 in External Solid State Drives
Cons
- Runs warm during long sustained transfers
- Needs a quality USB-C cable to hit top speeds
- Pricier than internal drives of the same capacity
The Sandisk Extreme is the portable drive to beat in 2026. With 91,725 owner reviews sitting at a 4.6 average, it is the most battle-tested external SSD on this list. The IP65 rating, 3 meter drop protection, and 256-bit AES hardware encryption make it a strong travel companion for creators and field workers.
Performance lands right where SanDisk advertises: 1050 MB/s sequential reads over USB 3.2 Gen 2, which is fast enough to dump a 50 GB shoot in under a minute on a modern laptop. Owners report reliable sustained throughput for video backups, though the aluminum shell does get warm on long transfers. The included SanDisk Memory Zone app handles backups and password protection.
Compared with the Samsung T7 1TB below, the Extreme trades the T7’s aluminum unibody for a softer, more rugged chassis and a carabiner loop. The 2TB capacity is the bigger differentiator for most shoppers. Skip this one if you need a smaller, lighter pocket drive for daily phone use; the SSK Portable 500GB in slot 9 is built for that.
Pair it with a USB-C 10 Gbps cable and you have a backup drive that should outlast several laptop upgrades. Field photographers and video editors doing offload on set get the most out of it.
2. Samsung 870 EVO 1TB: Top Rated
Samsung SSD 870 EVO SATA III 2.5” 1TB, Read Speeds Up to 560MB/s
Capacity: 1TB
Interface: SATA III
Speed: 560 MB/s
Endurance: 600 TBW
Pros
- Proven Samsung reliability with 45598 owner reviews
- Sequential reads up to 560 MB/s and writes up to 530 MB/s
- AES 256-bit encryption and Samsung Magician software
- Up to 600 TBW endurance rating
- Standard 2.5 inch form factor for easy laptop swaps
Cons
- SATA caps out well below NVMe speeds
- Costs more per GB than QLC SATA drives
- Bulkier than an M.2 stick for the same capacity
When someone asks for the safe pick, we point to the 870 EVO. A 4.8 average across 45,598 reviews and a 600 TBW endurance rating make it the most-trusted SATA SSD in this lineup, and that trust has not faded into 2026.
Sequential reads hit 560 MB/s and writes land at 530 MB/s over SATA III, which is the ceiling for the interface. Real-world wins are boot times, application load, and silent operation versus an old spinning disk. The 2.5 inch form factor drops into most laptops and desktops without a caddy. Samsung Magician keeps firmware updated and lets you clone from an older drive.
Versus the fanxiang S101 in slot 10, the 870 EVO is the safer buy: a longer 5-year warranty, stronger brand support, and tighter firmware. The fanxiang is cheaper on a per-GB basis, but the EVO wins on longevity. Skip the 870 EVO if your motherboard has a free M.2 slot; a Gen 4 stick like the Kingston NV3 in slot 7 will be several times faster for not much more money.
Older laptops getting an SSD transplant, secondary game libraries on SATA-capable systems, and anyone who values a long warranty over cutting-edge speed will be happy with it. If your system only has SATA, this is the drive to put in it.
3. Samsung 9100 PRO 1TB: Best Value
Samsung SSD 9100 PRO 1TB, PCIe 5.0×4 M.2 2280, Up to 14,700MB/s
Capacity: 1TB
Interface: PCIe 5.0 x4
Speed: 14700 MB/s
Controller: 5nm
Pros
- Breakthrough PCIe 5.0 reads up to 14700 MB/s
- Random performance up to 1850K/2600K IOPS
- 5nm controller brings 49% better power efficiency
- Advanced thermal control to limit throttling
- Available in capacities up to 8TB
Cons
- Needs a PCIe 5.0 capable CPU and motherboard
- Premium pricing even with sale discounts
- Can still throttle in poorly ventilated cases
The Samsung 9100 PRO is the flagship to watch if you have a PCIe 5.0 system and a workload that can actually use the bandwidth. It posts 14,700 MB/s sequential reads and 13,300 MB/s sequential writes, with a 5nm controller that runs cooler than the first wave of Gen 5 drives.
Owners highlight the thermal design, which Samsung built specifically to deal with Gen 5 heat. The 49% power efficiency improvement over the 990 PRO matters in a small form factor build or a hot case. Random read IOPS top out at 1,850K and writes at 2,600K, which is a real step up for AI dataset loading and high-resolution video timelines.
Versus the Samsung 990 PRO 2TB in slot 4, the 9100 PRO roughly doubles peak bandwidth and improves efficiency, but it is still a niche pick. If your motherboard does not have a Gen 5 M.2 slot, you are paying for speed your system cannot use. Skip this one unless you are building around Intel Arrow Lake or AMD Ryzen 7000/9000 with a Gen 5-capable slot.
New-build creators with Gen 5 boards, AI dataset pipelines, and reviewers who want the headline spec are the audience. Most shoppers should save the money and go with the 990 PRO 2TB instead.
4. Samsung 990 PRO 2TB: Premium Pick
Samsung SSD 990 PRO 2TB, PCIe 4.0 M.2 2280, Up to 7,450 MB/s
Capacity: 2TB
Interface: PCIe 4.0 x4
Speed: 7450 MB/s
Endurance: 5-year
Pros
- Sequential reads up to 7450 MB/s and writes up to 6900 MB/s
- 55% better random performance than the 980 PRO
- Available up to 4TB for large game libraries
- Samsung Magician software for monitoring and tuning
- 5-year limited warranty
Cons
- Runs hot under sustained load without airflow
- Premium price versus other Gen 4 options
- Needs a free M.2 2280 slot
The 990 PRO 2TB is the drive we recommend to anyone who wants top-tier Gen 4 performance without paying for a Gen 5 system that may not exist yet. Sequential reads hit 7,450 MB/s and writes reach 6,900 MB/s, with a 55% random performance gain over the 980 PRO. Owner reviews sit at 4.7 across 13,420 ratings.
Samsung pairs the drive with Magician, which handles firmware updates, encryption setup, and health monitoring in one place. The 2TB capacity is the sweet spot for a game library plus a Windows install on a single drive. Reviewers note the drive runs hot under heavy sustained load, so plan for a heatsink or good case airflow.
Versus the Samsung 990 EVO Plus 1TB in slot 5, the 990 PRO offers higher peak writes and a real DRAM cache for sustained heavy workloads. The EVO Plus wins on efficiency and laptop thermals. If you need raw throughput for a content creation box, the 990 PRO is the better buy. For a daily-driver laptop where battery life and cool operation matter, the EVO Plus makes more sense.
Gaming PCs, content creation rigs, and anyone replacing a 980 PRO or older Gen 3 drive are the natural fits. This is the workhorse Gen 4 pick for the 2026 sale.
5. Samsung 990 EVO Plus 1TB: Best for Laptops
Samsung SSD 990 EVO Plus 1TB, PCIe Gen 4×4 | 5×2 M.2 2280, Up to 7,150 MB/s
Capacity: 1TB
Interface: PCIe 4.0 x4
Speed: 7150 MB/s
Thermals: Nickel-coated
Pros
- Sequential reads up to 7150 MB/s and writes up to 6300 MB/s
- Nickel-coated controller for better thermal control
- Backward compatible with PCIe 3.0 systems
- Intelligent TurboWrite 2.0 for sustained large file writes
- 5-year warranty
Cons
- Write speeds can drop when SLC cache fills
- Premium pricing for a mid-range Gen 4 stick
- No integrated heatsink in the box
The 990 EVO Plus is the quiet overachiever of Samsung’s Gen 4 lineup. A 4.8 average from nearly 7,000 owners backs a drive that pulls 7,150 MB/s reads and 6,300 MB/s writes while keeping thermals in check. The nickel-coated controller and Intelligent TurboWrite 2.0 help it stay cool in tight laptop chassis.
It also runs in PCIe 3.0 systems, which makes it a sensible upgrade path for older laptops that still have an M.2 slot. The 5-year warranty matches the more expensive 990 PRO. Owners do flag a write-speed drop after the SLC cache fills on long transfers, but for everyday work and gaming, the EVO Plus holds up.
The WD_Black SN7100 in slot 6 is the alternative here, and the trade is straightforward: the EVO Plus wins on peak writes and Samsung’s software, while the SN7100 wins on power efficiency for Steam Deck-class handhelds. Pick the EVO Plus for a thin-and-light laptop build, and pick the SN7100 if battery life and handheld thermals are the priority.
Ultrabooks, productivity laptops, and anyone who values cool operation over absolute peak speed are the audience.
6. WD_Black SN7100 1TB: Best for Handhelds
WD_Black SN7100 1TB NVMe SSD – Gen4 PCIe, M.2 2280, Up to 7,250 MB/s Read Speed, Up to 6,900 MB/s Write Speed, Next Gen TLC 3D NAND, for Laptops, Handheld Gaming Devices – WDS100T4X0E
Capacity: 1TB
Interface: PCIe Gen 4
Speed: 7250 MB/s
Power: 100% more efficient
Pros
- Up to 7250 MB/s read and 6900 MB/s write on PCIe Gen 4,100% better power efficiency than the previous gen
- Single-sided M.2 2280 fits Steam Deck and ROG Ally
- Next gen TLC 3D NAND for endurance
- Runs cool without a heatsink
Cons
- Can throttle under extremely heavy sustained writes
- WD Dashboard software feels dated
- Not the fastest Gen 4 option at this capacity
The WD_Black SN7100 is the Gen 4 stick that handheld PC owners keep recommending. It hits 7,250 MB/s reads, 6,900 MB/s writes, and uses roughly half the power of the previous generation. That power figure is the reason it makes sense in a Steam Deck OLED or an ASUS ROG Ally X, where every watt matters.
Its single-sided M.2 2280 layout fits the cramped M.2 2230-to-2280 adapters that the handheld modding community uses, and it runs cool without a heatsink. TLC 3D NAND is a sensible pick for endurance versus QLC. Reviewers note the drive can throttle under very heavy sustained writes, but most gaming workloads never hit that ceiling.
The Samsung 990 EVO Plus in slot 5 is the natural alternative, and the trade is speed versus efficiency. The EVO Plus wins on raw peak performance and software polish, while the SN7100 wins on power draw and is the better pick for a Steam Deck, Ally, or any battery-sensitive laptop. For a desktop daily-driver, the EVO Plus is the more sensible choice.
Handheld gaming PC owners, frequent travelers who need cool and efficient storage, and anyone who values battery life over peak speed are the audience.
7. Kingston NV3 1TB: Best Budget NVMe
Kingston NV3 1TB M.2 2280 NVMe SSD | PCIe 4.0 Gen 4×4 | Up to 6000 MB/s | SNV3S/1000G
Capacity: 1TB
Interface: PCIe 4.0 x4
Speed: 6000 MB/s
Software: Acronis
Pros
- Up to 6000 MB/s read and 4000 MB/s write on PCIe Gen 4
- Low power draw and cool operation without a heatsink
- Includes Acronis True Image cloning software
- HMB (Host Memory Buffer) for efficient operation
- 5-year limited warranty
Cons
- DRAM-less design limits extreme sustained workloads
- Write speeds can vary with very large file transfers
- No integrated heatsink
The Kingston NV3 is the budget Gen 4 NVMe to watch in 2026. It runs 6,000 MB/s reads, 4,000 MB/s writes, and stays cool without a heatsink. Through the year, the price has trended down, and Prime Big Deal Days is the moment community trackers expect the deepest cut of the season on this model.
Kingston includes Acronis True Image cloning software, which is a real value-add at the budget end of the market. HMB (Host Memory Buffer) lets the drive borrow system memory instead of using a DRAM cache, which keeps the cost down but does cap sustained performance. Owners give the NV3 a 4.7 average across nearly 14,000 reviews, which is strong for a budget drive.
The fanxiang S101 in slot 10 is the SATA alternative at a similar price, and the rule is simple: if your motherboard has an M.2, the NV3 is several times faster. Skip the NV3 if you need heavy sustained writes (large video exports) where DRAM cache matters, since HMB caps that workload. For most users, it is a low-cost entry into NVMe without paying for premium specs.
First-time PC builders on a budget, laptop upgrades from a small OEM drive, and secondary game storage are the audience. See our guide on why a new SSD may not show up in Windows if your install hits a snag.
8. Samsung T7 1TB Portable: Best for Creators
Samsung T7 Portable SSD 1TB Titan Gray, USB 3.2 Gen 2, Up to 1,050MB/s
Capacity: 1TB
Interface: USB 3.2 Gen 2
Speed: 1050 MB/s
Build: Aluminum
Pros
- Up to 1050 MB/s read and 1000 MB/s write over USB 3.2 Gen 2
- Solid aluminum unibody with 6 foot shock resistance
- AES 256-bit hardware encryption
- Direct 4K 60 fps recording support for cameras and consoles
Cons
- Write speeds can dip on very large files
- Needs the included USB-C cable for top speed
- No carrying case in the box
Owners love the Samsung T7 for one specific reason: it is the portable drive that disappears into a coat pocket without feeling cheap. A 4.7 average across more than 21,000 ratings and a solid aluminum unibody make it the most pocketable drive in this lineup.
It runs at the same 1,050 MB/s ceiling as the Sandisk Extreme but in a noticeably smaller, all-aluminum body. The 4K 60 fps direct recording support is a real plus for content creators shooting to the drive straight from a camera or console, and the AES 256-bit encryption keeps client footage safe. The aluminum shell helps with heat dissipation, though the drive still warms up under long sustained writes. Owners do flag a slight write-speed drop on multi-gigabyte transfers, but for daily creator work, the T7 holds up.
The Sandisk Extreme 2TB in slot 1 has twice the capacity and a tougher IP65 rating, but it is bigger and heavier. Pick the T7 if you want the most pocketable drive in the list. Pick the Extreme if you need 2TB and a rugged rating for travel.
Good to know: if you are initializing the T7 for the first time, the Mac and Windows guides linked here walk through the steps for both file systems.
9. SSK Portable 500GB: Best for iPhone
SSK Portable SSD 500GB External Solid State Hard Drive USB C Up to 1050MB/s
Capacity: 500GB
Interface: USB 3.2 Gen 2
Speed: 1050 MB/s
Build: Aluminum
Pros
- Up to 1050 MB/s read and 1000 MB/s write on USB 3.2 Gen 2
- Direct iPhone ProRes 4K recording support
- Includes both USB-C and USB-A cables
- Aluminum case for better heat dissipation
- S.M.A.R.T. health diagnostics and TRIM support
Cons
- Capacity shows around 465 GB on Windows due to binary math
- Some users report small panel gaps on the case
- Initial formatting can take several minutes
The SSK Portable 500GB is the small, fast drive that iPhone 15 and 16 Pro owners have been buying for ProRes capture. It hits the 1,050 MB/s USB 3.2 Gen 2 ceiling, ships with both USB-C and USB-A cables in the box, and works with iOS file apps out of the box.
The 2 mm aluminum case does a decent job pulling heat away from the controller, which matters when you are recording 4K ProRes straight to the drive. The S.M.A.R.T. monitoring and TRIM support help with long-term reliability. Owners give it a 4.5 average across more than 3,700 reviews, which is strong for a budget portable.
The Sandisk Extreme in slot 1 is the larger alternative with an IP65 rating and 2TB of capacity, but it is bigger and heavier. The SSK is the phone-friendly pick: smaller, lighter, and tuned for direct capture from a phone or tablet. Pick the SSK for iPhone ProRes or daily coursework backups. Pick the Extreme for travel and 2TB of rugged storage.
iPhone ProRes videographers, students backing up coursework, and anyone who needs a pocket drive for phone capture are the audience. If the drive is not appearing on your desktop after first plug-in, our BIOS-but-not-Windows fix guide covers the usual causes.
10. fanxiang S101 1TB SATA: Most Versatile
fanxiang S101 1TB SSD SATA SSD 1TB Internal Solid State Drive SATA III 6Gb/s 2.5″ SSD, UP to 520MB/s, 3D NAND TLC, Upgrade Laptop PC and Desktops
Capacity: 1TB
Interface: SATA III
Speed: 520 MB/s
NAND: TLC
Pros
- Up to 520 MB/s reads and 480 MB/s writes on SATA III
- 3D NAND TLC for better endurance than QLC
- Compatible with desktops, laptops, and all-in-one PCs across Windows
- Linux, and Mac OS
- 3-year after-sales service
Cons
- Slower than any NVMe alternative
- Smaller brand with limited support outside Amazon
- May not bundle cloning software
The fanxiang S101 sits in an awkward middle ground: not the cheapest, not the fastest, but a 1TB SATA drive with TLC NAND and a 4.5 average across 23,000+ owner reviews. For a plain HDD-to-SSD swap, it does the job without any extras to think about.
Sequential reads land at 520 MB/s and writes at 480 MB/s over SATA III, which is the ceiling for the interface. The TLC 3D NAND is a real plus versus the QLC drives in the same price range, and 3-year after-sales service is in the box. Make sure your laptop has a 2.5 inch bay or a SATA caddy before buying. Compatibility covers desktops, laptops, and all-in-one PCs across Windows, Linux, and Mac OS.
Skip this one if your motherboard has a free M.2 slot, since a Gen 4 stick like the Kingston NV3 in slot 7 will be several times faster for not much more money. The Samsung 870 EVO in slot 2 is the safer brand pick for the same capacity if you want a longer 5-year warranty and tighter firmware support.
Good to know: the S101 is one of the easiest drop-in upgrades you can do on a 5-to-10-year-old laptop, and a single screw in most cases is all that holds the old drive in place.
11. PNY CS900 250GB: Best for Old Laptops
PNY CS900 250GB 2.5″ SATA III Internal SSD
Capacity: 250GB
Interface: SATA III
Speed: 535 MB/s
Warranty: 3-year
Pros
- Up to 535 MB/s read and 500 MB/s write on SATA III
- Ultra-low power consumption for older laptops
- Backward compatible with SATA II 3 Gb/s
- Plug-and-play installation in 2.5 inch bays
- 3-year warranty
Cons
- 250GB is small for modern game libraries
- Sequential speeds trail NVMe by a wide margin
- No hardware encryption
The PNY CS900 250GB is the smallest drive on this list, and the right pick for an old laptop that just needs an SSD transplant to feel fast again. It tops out at 535 MB/s reads, runs cool, and installs in minutes in any 2.5 inch bay. Owner reviews sit at 4.7 across more than 5,400 ratings.
The 250GB capacity is the main limitation. It is enough for Windows and a basic app set, but a modern game library will not fit. Backward compatibility with SATA II 3 Gb/s is a real plus for very old machines that predate SATA III. PNY bundles a 3-year warranty, which is solid for a drive at this price.
The fanxiang S101 in slot 10 is the bigger alternative at 1TB, and the trade is brand familiarity versus capacity. The CS900 is the safer pick if you want a known brand and a 250GB boot drive, and the S101 is the better value if you need room for a photo library or a larger swap. For a 10-year-old laptop being revived for a student or a parent, the CS900 250GB is the right size.
Older laptops from 2012-2017 that need a small but fast boot drive, kiosks and secondary machines, and emergency replacements when a hard drive fails are the use cases. It is the cheapest way to give an old PC a few more useful years.
How to Choose SSDs During Prime Big Deal Days
Match the Interface to Your System
The single most important check is what your system can actually use. A laptop with only a SATA bay cannot accept an M.2 NVMe stick, and a desktop motherboard without a Gen 5 slot cannot feed a Gen 5 drive at full speed. The 870 EVO, S101, and CS900 cover SATA systems. The 990 PRO, 990 EVO Plus, SN7100, and NV3 are Gen 4 NVMe sticks. The 9100 PRO is Gen 5 NVMe and needs a current motherboard. For external needs, the Sandisk Extreme, T7, and SSK all use USB 3.2 Gen 2 over USB-C.
Decide Between Gen 4 and Gen 5
Gen 4 NVMe is the sweet spot in 2026. Drives like the 990 PRO and the SN7100 already saturate the bandwidth most games and apps can use, and they cost noticeably less than Gen 5. Gen 5 (the 9100 PRO) is worth it only if you have a compatible board and a workflow that actually pushes multi-gigabyte sequential reads, such as 8K video editing or AI dataset loading. For the average user, Gen 4 is the better value.
Pick the Right Capacity (1TB / 2TB / 4TB)
1TB is the new minimum for a primary drive, and 2TB is the right size for a modern game library. Community watchers track specific price ceilings during Prime events; the goal is to match the lowest all-time price on the model you want for each capacity. 250GB and 500GB are fine for secondary roles or older systems. Going one tier bigger than you think you need is usually a good idea, since filling an SSD close to capacity hurts sustained performance.
DRAM vs HMB and Why It Matters
SSDs with a DRAM cache (the 990 PRO, 870 EVO) hold up better under heavy random writes, which matters for database work, compilation, and large file servers. HMB drives like the Kingston NV3 and the WD SN7100 borrow a slice of system RAM instead of carrying their own cache, which keeps the price down and the thermals low. For most gaming and everyday work, HMB is fine. If you run sustained heavy writes, spend the extra for a DRAM-equipped drive.
Heatsink and PS5 Compatibility
Any high-performance NVMe stick, especially the 990 PRO and the 9100 PRO, will throttle in a poorly ventilated case. A simple M.2 heatsink or motherboard shroud is enough. For a PS5 expansion, the console requires a drive with a heatsink no thicker than roughly 11 mm. None of the drives on this list ship with a PlayStation-compatible heatsink out of the box, so plan on a third-party heatsink or a PS5-ready variant if that is your use case.
How to Shop SSD Deals During the Sale
Prime Big Deal Days runs October 6-7, 2026, and most offers need a Prime membership (a free trial counts). Prices on SSDs can shift by the hour during the event, so set a CamelCamelCamel alert on the exact model number before the sale opens. Check that the listing is sold by Amazon or a known retailer, since third-party Marketplace sellers sometimes inflate list prices to fake a deeper discount. Watch for lightning deals on the Gen 4 sweet spot, since those caps tend to move the most during the first 12 hours. Older model years (a 980 PRO, a T5) can also be a good value if you do not need the latest firmware.
Quick checklist for SSD deal shopping:
- Confirm your motherboard or laptop has the right slot before adding to cart.
- Set a CamelCamelCamel alert on the exact model number (for example MZ-V9P2T0B/AM).
- Check the seller and shipping notes, not just the headline price.
- Cap your budget at the community price ceiling for that capacity.
- Buy the biggest capacity you can justify; SSD performance drops as they fill up.
Frequently Asked Questions
When does Prime Big Deal Days 2026 start and how long does it last?
Prime Big Deal Days runs October 6-7, 2026. The event is a 48-hour sale on Amazon, with most offers requiring a Prime membership. A free 30-day Prime trial counts, and students usually get a longer trial.
Are Prime Big Deal Days SSD prices actually lower than normal?
Discounts during Prime Big Deal Days are usually real on popular models like the 990 PRO and the Sandisk Extreme, but some listings inflate the list price to make the discount look larger. Use a price tracker like CamelCamelCamel to confirm the all-time low before you buy.
What SSD should I buy for a PS5 during Prime Big Deal Days?
The PS5 accepts an M.2 2230 or 2280 NVMe drive with a heatsink no thicker than about 11 mm and sequential reads above 5,500 MB/s. The Samsung 990 PRO 2TB and the WD_Black SN7100 1TB both clear the speed bar; you will need to add a third-party heatsink since neither ships with one.
Is PCIe 5.0 worth buying in 2026?
Only if your motherboard has a Gen 5 M.2 slot and your workflow can use the bandwidth, such as 8K video editing or AI dataset loading. For gaming and everyday productivity, a Gen 4 drive like the 990 PRO is the better value.
How do I know if an SSD deal is a real discount?
Check the all-time low on a price tracker, compare the current price to the 90-day average, and confirm the seller is Amazon or a known retailer. If the list price is higher than the highest tracker entry, the discount is likely inflated.
Final Verdict: Amazon Prime Big Deal Days SSD Deals
The drive most worth watching during the sale is the Sandisk Extreme 2TB Portable, our EDITOR’S CHOICE for its mix of capacity, IP65 rating, and a 91,000-review track record. For internal NVMe, the Samsung 990 PRO 2TB is the Gen 4 workhorse to put in a gaming or content creation build. The Samsung 9100 PRO 1TB Gen 5 is the right pick only for new Gen 5 builds that can actually feed it.
On a tighter budget, the Kingston NV3 1TB is the best Gen 4 value and the Samsung 870 EVO 1TB is the safest SATA bet. Handheld PC owners should grab the WD_Black SN7100 1TB, iPhone ProRes users should pick up the SSK Portable 500GB, and the PNY CS900 250GB remains the cheapest way to revive an older laptop. Prices move fast during the event, so set a CamelCamelCamel alert on the exact model number before the sale opens and buy the moment your target price lands.
