How We Chose
We compared ten SSDs against their published read and write speeds, the owner rating and the total number of reviews on Amazon, and the warranty length listed by each maker. The data was checked in October 2026 against each product's current Amazon listing, and the table above uses the same fields in the same order for every model so the rows line up cleanly. Deals change through the event, so the table points to each listing rather than locking in a number.
1. Samsung SSD 990 PRO 1TB: Editor's Choice
Samsung SSD 990 PRO 1TB, PCIe 4.0 M.2 2280, Up to 7,450 MB/s
Type: PCIe 4.0 NVMe
Read: 7450 MB/s
Write: 6900 MB/s
Capacity: 1TB
Warranty: 5 year
+ Pros
- Up to 7450 MB/s read speed
- Strong endurance ratings
- Compact M.2 2280 form factor
- Trusted Samsung Magician software
- Cons
- Runs warm under sustained load
- Premium tier pricing
Across 13400 owner reviews the Samsung 990 PRO holds a 4.7-star average, which is the kind of long-running owner trust that a PCIe 5.0 drive has not earned yet. Buy the 990 PRO if you want one drive that covers a fast boot drive, a Steam library and a working video timeline without compromise.
- Read 7450 MB/s and write 6900 MB/s on a Gen4 x4 slot
- 13400 owner reviews at a 4.7-star average
- Samsung Magician for cloning, firmware and health monitoring
- 1TB version carries a 5 year warranty
Owners report very quick load times on PS5 and PC, and the drive holds sustained writes for creators who push large project files. The trade-off several reviews mention is heat: under heavy sequential writes the 990 PRO can run warm in a case with poor airflow, so a basic M.2 heatsink helps.
For everyone else on a current AMD or Intel board with Gen4 lanes, this drive still uses every bit of bandwidth the slot can give it. The Samsung 9100 PRO below is the cleaner pick if you specifically want the peak bandwidth of PCIe 5.0 and a motherboard that exposes those lanes.
2. Samsung SSD 9100 PRO 1TB: Most Compact
Samsung SSD 9100 PRO 1TB, PCIe 5.0x4 M.2 2280, Up to 14,700MB/s
Type: PCIe 5.0 NVMe
Read: 14700 MB/s
Write: 13300 MB/s
Capacity: 1TB
Warranty: 5 year
+ Pros
- Up to 14700 MB/s read speed
- Future proof for Gen5 boards
- Advanced thermal solution
- 5 year warranty
- Cons
- Requires a PCIe 5.0 motherboard
- Higher entry price than Gen4 drives
If your system has PCIe 5.0 lanes, the Samsung 9100 PRO is the drive to watch on Prime Big Deal Days: at 14700 MB/s read it roughly doubles what the 990 PRO can do. The 4.7-star rating across 1800 owner reviews is still early but consistent with Samsung's recent SSD launches.
- Read reaches 14700 MB/s on a Gen5 x4 slot
- Advanced thermal design for sustained Gen5 loads
- 1TB model backed by a 5 year warranty
- Best fit for content creators and early Gen5 adopters
For most people the 9100 PRO is overkill, but for people moving multi-gigabyte project files in Premiere Pro or DaVinci Resolve, the extra bandwidth compounds over a full workday. Samsung tuned this drive to handle the higher power draw of Gen5 without throttling, and reviews note the drive stays inside a sensible temperature range with the motherboard's stock M.2 shield.
The 990 PRO delivers similar real-world responsiveness without the Gen5 price tag, which is the more sensible pick for a Gen4 system. For anyone shopping a thin laptop instead, our deals on portable gear cover other storage tiers worth comparing.
3. WD_BLACK SN850X 1TB: Best for Gaming
WD_BLACK SN850X 1TB NVMe SSD - M.2 2280, Up to 7,300 MB/s Read speeds, Up to 6,300 MB/s write...
Type: PCIe 4.0 NVMe
Read: 7300 MB/s
Write: 6300 MB/s
Capacity: 1TB
Warranty: 5 year
+ Pros
- Up to 7300 MB/s read speed
- Gaming optimized firmware
- Strong load time performance
- Optional heatsink model
- Cons
- Runs hot under sustained load
- Premium price for Gen4
With 6500 owner reviews and a 4.8-star average, the WD_BLACK SN850X is one of the most consistently rated gaming SSDs in this lineup, and a popular pick for Prime events. WD_BLACK tuned the controller for the kind of mixed read and write patterns that open-world games create, and reviewers report noticeably faster texture streaming in supported titles.
The 6300 MB/s write ceiling also covers Steam library moves without a long stall, and the optional heatsink version is worth considering for a small form factor build. The trade-off several reviews mention is heat: under heavy sustained writes the SN850X can run warm in a case with poor airflow.
- Sequential read at 7300 MB/s and write at 6300 MB/s on Gen4
- 6500 owner reviews at a 4.8-star average
- Gaming-optimized firmware for DirectStorage loads
- Heatsink version available for small form factor builds
For workloads that are mostly sequential file transfers, the Samsung 990 PRO trades blows at a similar price, so the SN850X is not always the only answer. If you want a gaming-leaning drive but your chassis is a Steam Deck or a thin laptop, the WD_BLACK SN7100 below is the more efficient choice for battery-bound devices.
4. 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...
Type: PCIe 4.0 NVMe
Read: 7250 MB/s
Write: 6900 MB/s
Capacity: 1TB
Warranty: 5 year
+ Pros
- Up to 7250 MB/s read speed
- Energy efficient for laptops
- Good for Steam Deck upgrades
- TLC 3D NAND
- Cons
- Slower than flagship Gen4 drives
- Write speeds vary by capacity
For a Steam Deck, ASUS ROG Ally or a thin-and-light laptop where battery life and heat matter as much as peak speed, the WD_BLACK SN7100 is the drive to shortlist. At 7250 MB/s read and a 4.8-star owner rating across 6500 reviews, it is one of the more efficient Gen4 drives on this list.
Owners report strong sustained performance without throttling, which matters in a handheld where there is no room for a heatsink. The TLC 3D NAND also gives the drive better endurance than QLC alternatives, and that combination is the main reason it shows up in so many handheld upgrade guides.
- Sequential read at 7250 MB/s and write at 6900 MB/s on Gen4
- Lower power draw than the SN850X for battery life
- TLC 3D NAND for stronger endurance than QLC drives
- Fits the 2230 or 2280 slot in the Steam Deck and Ally
On a desktop with a Gen4 slot and a real heatsink, the WD_BLACK SN850X above is the more desktop-friendly choice with a gaming-leaning firmware. For anyone shopping a thin laptop, our roundup of MacBook Air deals during past sales is a useful frame for matching storage to chassis.
5. Crucial P310 1TB: Best Value
Crucial P310 1TB SSD, PCIe Gen4 NVMe M.2 2280, Up to 7,100MB/s, for Laptop, Desktop (PC), & Handheld...
Type: PCIe 4.0 NVMe
Read: 7100 MB/s
Write: 6000 MB/s
Capacity: 1TB
Warranty: 5 year
+ Pros
- Up to 7100 MB/s read speed
- Includes Acronis Data Recovery
- Strong price to performance
- Wide compatibility
- Cons
- No heatsink included
- Lower endurance than premium models
The 4.7-star owner rating across 11200 reviews makes the Crucial P310 one of the most heavily reviewed picks in the list, and the 7100 MB/s read ceiling beats the Kingston NV3 on paper. What stands out is the Acronis Data Recovery software that Crucial bundles in the box, which on its own covers the cost of a separate cloning tool.
Reviews mention that the cloning flow is smooth and the recovery tool has rescued a few bad updates, which is a meaningful extra at this tier. The P310 also covers a wide compatibility range, working in a laptop, a desktop or a handheld gaming console without a special driver or firmware step.
- Read hits 7100 MB/s on a Gen4 slot
- 11200 owner reviews at a 4.7-star average
- Acronis Data Recovery bundled in the box
- 5 year warranty
For gaming workloads that need the WD_BLACK firmware tuning, the P310 is a generalist at heart, and a desktop-only build may get more from the SN850X above. The P310 also ships without a heatsink, so a small form factor desktop build should add a basic M.2 shield.
6. Kingston NV3 1TB: Most Versatile
Kingston NV3 1TB M.2 2280 NVMe SSD | PCIe 4.0 Gen 4x4 | Up to 6000 MB/s | SNV3S/1000G
Type: PCIe 4.0 NVMe
Read: 6000 MB/s
Write: 4000 MB/s
Capacity: 1TB
Warranty: 3 year
+ Pros
- Up to 6000 MB/s read speed
- Budget friendly price
- Reliable Kingston brand
- Easy system upgrade
- Cons
- No DRAM cache
- Write speeds trail premium Gen4 drives
Upgrading an older system and want a recognizable brand at the lowest end of the Gen4 range? The Kingston NV3 is the budget pick to watch. The 4.7-star owner rating across 14000 reviews is one of the highest review counts on this list, and that is a useful signal for a mainstream upgrade.
Owners report that the NV3 is a clean swap for an aging SATA SSD or a hard drive, and that boot times drop sharply even at 6000 MB/s. The lack of a DRAM cache shows up in heavy random writes, but for a boot drive or a game library the difference is small in everyday use.
- Read of 6000 MB/s on a Gen4 slot
- 14000 owner reviews at a 4.7-star average
- 3 year warranty
- Clean swap for an aging SATA SSD or a hard drive
Sustained video editing or large database writes are the workloads where the lack of DRAM hurts; that is not the NV3's target. For a SATA-only motherboard, the PNY CS900 below is the matching budget pick, and the Crucial P310 above is the step up with Acronis in the box.
7. Samsung T7 Portable 1TB: Best Portable
Samsung T7 Portable SSD 1TB Titan Gray, USB 3.2 Gen 2, Up to 1,050MB/s
Type: USB 3.2 Gen 2
Read: 1050 MB/s
Write: 1000 MB/s
Capacity: 1TB
Warranty: 3 year
+ Pros
- Up to 1050 MB/s transfer speed
- Compact pocket sized design
- USB-C connectivity
- Durable aluminum body
- Cons
- Slower than internal NVMe drives
- Premium price for external storage
The Samsung T7 is the portable SSD to beat, and it is worth watching during Prime Big Deal Days because Samsung drops this drive every major sale. The 4.7-star rating across 21200 owner reviews is a useful signal of long-term reliability for a drive that has been in pockets and camera bags for years.
What stands out is the size: at 3.39 x 2.24 x 0.32 inches and 2.08 ounces, the T7 disappears in a laptop sleeve. The USB 3.2 Gen 2 interface pushes real-world transfers close to 1050 MB/s on a USB-C 3.2 host, which is fast enough to edit 4K footage off the drive on a modern laptop.
- Transfer ceiling of 1050 MB/s over USB 3.2 Gen 2
- Compact 3.39 x 2.24 x 0.32 inch frame
- Aluminum body, USB-C connectivity
- 3 year warranty
For anyone who needs more than 2TB of portable storage, the SanDisk 2TB Extreme below is the stronger high-capacity pick. For travel and a daily commute, however, the T7's pocket size is the right call, and our past sale write-ups show how often Samsung drops portable storage during Amazon's fall events.
8. SanDisk Extreme Portable 2TB: Best High-Capacity Portable
Sandisk 2TB Extreme Portable SSD, Up to 1050MB/s, USB-C, USB 3.2 Gen 2, IP65 Water and Dust...
Type: USB 3.2 Gen 2
Read: 1050 MB/s
Write: 1000 MB/s
Capacity: 2TB
Warranty: 5 year
+ Pros
- Up to 1050 MB/s transfer speed
- 2TB capacity
- IP65 water and dust resistance
- USB-C connectivity
- Cons
- Bulkier than the Samsung T7
- Write speeds can vary with capacity
With 91900 owner reviews and a 4.6-star average, the SanDisk Extreme Portable 2TB is the most-reviewed SSD in this list, and that scale of owner feedback is itself a useful signal for a drive that travels. The IP65 rating covers dust and water spray, and a silicone shell absorbs drops better than a bare metal enclosure.
At 2TB, the drive holds a large photo library or a working video project, and the 1050 MB/s ceiling keeps file transfers quick over USB 3.2 Gen 2. SanDisk updated this drive's firmware in recent years, and current listings reflect that revision.
- Transfer ceiling of 1050 MB/s over USB 3.2 Gen 2
- 2TB capacity in a rugged shell
- IP65 water and dust resistance
- 5 year warranty
For shoppers who want the lightest pocketable drive, the Samsung T7 above is the better travel shape at a lower capacity. Against any of the internal NVMe drives on this list, the SanDisk is a different category: it is a travel and backup drive, not a primary system drive.
9. PNY CS900 1TB SATA: Best SATA Upgrade
PNY CS900 1TB 2.5" SATA III Internal SSD
Type: SATA III 2.5 inch
Read: 560 MB/s
Write: 530 MB/s
Capacity: 1TB
Warranty: 3 year
+ Pros
- Up to 560 MB/s read speed
- Affordable HDD replacement
- Easy 2.5 inch install
- Reliable for everyday tasks
- Cons
- Slower than any NVMe SSD
- SATA III bandwidth limit
When the system you are upgrading does not have an M.2 slot, or you are reviving an older laptop that only takes a 2.5 inch drive, the PNY CS900 is the right pick. The 4.7-star owner rating across 6100 reviews shows that for everyday computing the CS900 feels fast enough to replace a spinning hard drive.
The CS900 does not pretend to be a performance drive; it is a budget SATA SSD that hits the SATA III ceiling at around 560 MB/s, which is the maximum any SATA drive can deliver. Owners report clean installs and quick boot times once they clone an old drive over.
- Read of 560 MB/s on SATA III
- Standard 2.5 inch form factor, ships with a spacer
- 3 year warranty
- 6100 owner reviews at a 4.7-star average
For systems with an open M.2 slot, any of the NVMe drives above will be a much bigger jump. For an older office PC or a SATA-only laptop, however, the CS900 is a clean quality-of-life upgrade that you can feel on every boot and every program launch.
10. WD Blue SN5100 1TB: Top Rated
WD Blue SN5100 1TB NVMe SSD - M.2 2280, PCIe Gen 4.0, Internal Solid State Drive - Read Speeds Up to...
Type: PCIe 4.0 NVMe
Read: 7100 MB/s
Write: 5800 MB/s
Capacity: 1TB
Warranty: 5 year
+ Pros
- Up to 7100 MB/s read speed
- Low power consumption
- 5 year warranty
- Good upgrade value
- Cons
- Lower write speeds than competitors
- Newer product with fewer reviews
The most recent Gen4 drive in the lineup, the WD Blue SN5100, sits at a 4.8-star average across 925 owner reviews and earns the top rated badge on early feedback. It targets the same mainstream PC upgrade as the Crucial P310 but with newer silicon and a 5 year warranty.
What stands out is the low power draw, which makes the SN5100 a strong pick for a small form factor desktop or a quiet workstation build. Reviewers note consistent performance on a clean install with a fresh motherboard slot, and the 7100 MB/s read speed is competitive in the Gen4 tier.
- Read hits 7100 MB/s and write 5800 MB/s on Gen4
- Low power draw for SFF and quiet builds
- 5 year warranty
- 925 owner reviews at a 4.8-star average
For shoppers who want the bundled Acronis software the Crucial P310 includes, the SN5100 ships without cloning software in the box, which is the real trade-off. For a Steam Deck or laptop, the WD_BLACK SN7100 above is the more efficient sibling in the same family of controllers.
How to Choose SSDs During Prime Big Deal Days
Match the Interface to Your Motherboard
An NVMe M.2 drive only hits its rated speeds on an M.2 slot that exposes the right PCIe generation. A Gen4 drive like the 990 PRO tops out around 7450 MB/s on a Gen4 slot and runs at Gen3 speeds on older boards. Check your motherboard's chipset for M.2 support before you chase a Gen5 number.
Pick Capacity by Real Workload
For a Windows boot drive with light apps, 1TB is the modern floor. For a Steam library, aim for 2TB or more so a few big installs do not crowd the drive. For video work, 2TB and up gives you room for project files plus a current export without offloading to a second drive.
Read the Sequential and Random Numbers Together
Sequential read and write are the headline numbers, but random read and write at low queue depths are what makes a system feel fast day to day. Drives with a DRAM cache like the Samsung 990 PRO tend to hold up better in random workloads than DRAMless drives like the Kingston NV3, especially in heavy multitask use.
Decide Between Internal and Portable
Internal NVMe drives are for a primary PC or PS5 boot drive. Portable drives like the Samsung T7 and SanDisk Extreme are for travel, offloads, and editing on the go. If you mainly want to back up photos and game saves, a rugged portable with IP65 is worth the extra weight.
How to Shop SSD Deals During the Sale
Check the model year or generation in the listing title before you add the drive to your cart, because Prime Big Deal Days mixes the current model with the previous generation at tempting numbers. Confirm the capacity matches what the product image shows, since 500GB and 1TB versions of the same drive often share a photo. Look for who sells and ships the listing, and check the warranty line for the five-year coverage that most of these drives carry. Prime Big Deal Days runs October 6-7, 2026, and most offers need a Prime membership, with a free trial counting toward the requirement, and prices change through the event so the current price is always on the listing page.
- Confirm the motherboard's M.2 generation before you pick a Gen4 or Gen5 drive.
- Match capacity to workload: 1TB for general use, 2TB and up for game libraries and video projects.
- Check whether the drive includes a heatsink or whether your board has an M.2 shield.
- Verify the seller, the model number, and the warranty length on the listing page.
- Watch for Acronis or Samsung Magician bundles, which can save a separate software purchase.
Frequently Asked Questions
When is Prime Big Deal Days 2026?
Prime Big Deal Days runs October 6-7, 2026, and the deepest discounts usually hit on the first day. Most offers need a Prime membership, and a free trial counts. Prices can shift through the event, so the listing page is the only source for the current number.
Are Prime Big Deal Days SSD deals worth it?
Prime Big Deal Days is usually the best window to buy SSDs before Black Friday, and the past two events have featured noticeable markdowns on Gen4 NVMe drives. Compare the sale price to the past month's listing and to other retailers, since some discounted prices are not as deep as the headline suggests.
What SSD deals are worth watching on Prime Big Deal Days 2026?
Watch the Samsung 990 PRO and the WD_BLACK SN850X for Gen4 performance, the Samsung 9100 PRO if you have a Gen5 slot, and the Crucial P310 for value. For portable storage, the Samsung T7 and the SanDisk Extreme tend to drop every major sale.
Are SSD prices expected to drop further?
SSD prices have stayed higher than the pre-2024 baseline because of supply and demand shifts in the NAND market, and reviews on retailer forums report limited room for further cuts. Prime Big Deal Days usually matches the lowest price of the year so far, but waiting past Black Friday is rarely worth it for general users.
How do I tell if an SSD deal is a genuine discount?
Compare the sale price to the 30-day and 90-day price on a tracker before you buy, and check the listing for the specific capacity and model number. A real deal shows a recent price drop, while inflated original prices stay flat for months and then drop briefly. Owners in community forums also share the actual prices they paid as a benchmark.
Do I need a PCIe 5.0 SSD for gaming?
For most games today, a quality Gen4 NVMe drive is fast enough, and the WD_BLACK SN850X or the Samsung 990 PRO cover the DirectStorage-friendly loads that current titles use. A Gen5 drive like the Samsung 9100 PRO only helps if your motherboard has a Gen5 slot and your workload moves very large files regularly.
Final Verdict: Prime Big Deal Days SSD Deals
Buy the Samsung 990 PRO if you want a do-it-all Gen4 NVMe drive that covers a fast boot, a game library and a working video timeline with a 4.7-star owner rating. Buy the Samsung 9100 PRO if you have a Gen5 motherboard and want the headroom for large file moves. Buy the WD_BLACK SN850X for a gaming-leaning Gen4 drive with a heatsink option, and the WD_BLACK SN7100 for a Steam Deck or laptop. Buy the Crucial P310 for the strongest value play with Acronis in the box, and the Kingston NV3 if you are working with a tighter budget. For travel and backup, the Samsung T7 is the lightest pick, while the SanDisk Extreme 2TB is the rugged high-capacity option, and the PNY CS900 covers any system that still needs a 2.5 inch SATA drive. Prime Big Deal Days SSD deals shift through the event, so check the current listing before you commit and pick the model that matches the slot, capacity and workload you actually have.
