Storage is where a first-time upgrader feels the difference most, and the Crucial BX500 4TB is the drive to watch during Prime Big Deal Days this year. It holds a 4.8 average across more than 36000 owner reviews, the deepest rating base of any pick in this list, and it gives you 4TB of capacity for the kind of machine that still boots off a hard drive.
The two alternatives worth watching are the WD_BLACK SN850P 2TB, officially licensed for PlayStation 5 expansion, and the Crucial P310 2TB, a PCIe 4.0 drive that fits gaming PCs, laptops and handhelds alike. Amazon’s October event runs October 6-7, 2026, and most offers need an active Prime membership, though a free trial counts. Deals shift through the event, so treat these as the drives worth watching rather than confirmed discounts.

One warning before the picks. Amazon sets its own reference prices, and a “was” figure on a listing is not always a price the drive actually sold for. Check the history for the exact model number before you treat any number as a real cut.
How We Chose
Every drive here was compared on the specifications that decide an SSD purchase: capacity, interface, form factor, sequential and write speeds, NAND type, thermal design, warranty length and owner rating volume on Amazon. Ratings and review counts were read from the listings in October 2026.
1. Crucial BX500 4TB: Editor’s Choice for Storage-Heavy Upgrades
- Deepest review base in this list at 4.8 stars
- 4TB of capacity for bulk media and game libraries
- Acronis True Image cloning software included
- Hardware 256-bit AES encryption
- Works in any SATA laptop or desktop
- DRAM-less design slows under sustained heavy writes
- SATA III caps throughput near 540MB/s
- Not aimed at performance or enthusiast workloads
The highest-rated drive here on the deepest review base, and the way to add 4TB to a machine with no M.2 slot.
This is the revival pick. Owners describe the same thing repeatedly: fitting a BX500 into an ageing laptop or desktop and watching boot times, launch times and file opens change character. At 4TB, it also handles the “I keep deleting games to make room” problem that a 1TB drive never solves.
The trade-off is honest and worth stating plainly. This is a DRAM-less SATA drive, so write performance dips under long uninterrupted transfers, and the SATA III interface tops out near 540MB/s. Buyers who wanted an enthusiast drive overpaid for the wrong class of product.
Compared with the Crucial P310 2TB, the BX500 gives you twice the room at a fraction of the speed ceiling. If your machine has a SATA connector and no NVMe slot, the P310 is not an option at all, which is exactly why the BX500 earns its place here.
The box includes Acronis True Image HD for cloning your old drive, so the migration is a one-app job rather than a reinstall of everything.
2. WD_BLACK SN850P 2TB: Top Rated for PlayStation 5 Expansion
- Officially licensed for PlayStation 5
- Heatsink shaped for the console expansion bay
- 7300MB/s read on PCIe Gen 4
- Run games directly from the drive without deleting titles
- 5-year limited warranty
- Heatsink version only fits the PS5 expansion bay
- Needs a console software check for full official compatibility
Buy this one if you own a PS5 and you have run out of console storage. The licence matters more than it sounds: an unbranded M.2 drive in a PS5 can refuse to run a game until you format it, while a licensed drive is recognised straight away.
Owners report load times that match the console’s own internal drive, and the custom heatsink drops into the expansion bay without clearance drama. At 2TB you gain room for a large chunk of a modern library rather than a handful of installs.
The limitation is reuse. This heatsink-equipped version is shaped for the console, so it is a poor fit for a desktop M.2 slot that already has its own heatsink. If your plan spans both a console and a PC, the WD_BLACK SN850X 2TB covers more ground.
Good to know: a firmware or system software check on the console confirms official compatibility, and it is worth doing before you move a game library across.
3. Crucial P310 2TB: Best Value for a First NVMe Upgrade
- 7100MB/s read and 6000MB/s write on Gen4
- Recognised immediately with no driver fuss
- Runs cool under multi-app and video loads
- Works in laptops desktops and handhelds
- Backward compatible with Gen3 systems
- Gen3-only systems cap throughput far below the headline figure
- Mac laptops need a separate M.2 adapter
If you are building or upgrading a PC in 2026 and you want Gen4 speed without stepping up to a flagship, this is the sensible middle of the list. Buyers consistently describe it as fast boot, fast transfers, and a drive that stays cool under load.
The compatibility list is unusually wide for a value drive. Owners fit it in desktops, laptops and handheld consoles including the ROG Ally X, Lenovo Legion Go and AYANEO Kun, which makes it a natural pick if the machine is portable.
Owners do report one consistent limit: on a PCIe 3.0 machine you get a fraction of the advertised speed. That is a slot limitation rather than a fault in the drive, and it is why the WD Green SN350 2TB is the more honest buy for older boards.
Skip this one if your workload is sustained writing rather than loading and boot. The Crucial T500 2TB is built around that job.
4. Samsung 990 PRO 2TB: Best for Creative Workloads
- 7450MB/s read and 6900MB/s write
- Holds speed under 4K video editing loads
- Samsung Magician handles cloning and firmware
- 55% random performance gain over the 980 PRO
- 5-year manufacturer warranty
- Costs more than budget Gen4 alternatives
- No heatsink included so sustained loads can throttle
- Magician will not clone onto non-Samsung drives
Owners of this drive tend to use it the same way: a machine that opens large timelines and exports without the pauses a lesser drive introduces. It is the reference point most buyers compare other Gen4 options against, and reviewers describe years of steady use without drama.
The specs support that reputation. At 7450MB/s read and 6900MB/s write it sits at the top of the Gen4 class, with a 5-year manufacturer warranty behind it.
Two practical caveats. There is no heatsink on this version, so long sustained transfers benefit from an aftermarket cooler, and Magician will only clone onto Samsung drives. If you are moving from a different brand, budget a cloning tool or do a clean install.
Against the Crucial T500 2TB, the 990 PRO wins on raw speed and software polish. The T500 wins on TLC NAND for write-heavy sessions, which is a different kind of insurance.
5. WD Green SN350 2TB: Best for Older PCIe 3.0 Machines
Western Digital 2TB WD Green SN350 NVMe Internal SSD Solid State Drive – Gen3 PCIe, QLC, M.2 2280, Up to 3,200 MB/s – WDS200T3G0C
- Big responsiveness jump over a mechanical drive
- Low power draw suits always-on and small builds
- Standard M.2 2280 fits normal NVMe slots
- WD SSD Dashboard monitors drive health
- 3-year limited warranty
- QLC NAND is a poor fit for heavy write workloads
- Gen3 limits throughput to about 3200MB/s
- Mounting screw is not always included
A low-cost way to make an old PC feel new. Owners use the SN350 as a secondary game drive or to replace a hard drive in a machine that was never going to see a Gen4 slot, and they report speeds that comfortably beat SATA.
Being candid about the trade-off: this is QLC NAND on PCIe 3.0. That combination is excellent for reading games and running an operating system, and poor for hours of continuous writing such as a scratch drive for 4K footage.
A few reviewers report drives that failed to initialise in certain USB enclosures, so check your adapter if you plan to use it that way. The low power draw is a genuine advantage in an always-on machine or a laptop on battery.
This drive runs in any machine with a Gen3 or Gen4 M.2 slot, so it doubles as a safe secondary drive in a modern build.
6. Kingston NV3 2TB: Best for Laptops
Kingston NV3 2TB M.2 2280 NVMe SSD | PCIe 4.0 Gen 4×4 | Up to 6000 MB/s | SNV3S/2000G
- 6000MB/s read and 5000MB/s write on Gen4
- Single-sided board fits tight laptop slots
- Runs cool enough to avoid throttling under a bare heatsink
- Stable over months of daily use
- Backward compatible with Gen3 platforms
- DRAM-less so heavy write caches slow
- Endurance rating sits below premium Gen4 drives
Set-and-forget is the phrase reviewers keep using. Install it, forget it, and the machine boots faster and loads games faster, with no crashes or corrupted files reported even after long stretches of use on a nearly full drive.
The single-sided M.2 2280 layout is the detail that matters in a laptop. Thinner machines and some notebook bays have no clearance for a double-sided card, and this board fits where some of its competitors physically will not.
Owners accept the DRAM-less design because the host memory buffer keeps everyday performance smooth, but they are honest that sustained heavy writes will slow. For a laptop used for browsing, documents and games, that is rarely the deciding factor.
Where the Kingston NV3 differs from the Samsung 990 EVO Plus 1TB is capacity. Twice the room, slightly lower headline read speed, and a 3-year warranty instead of 5.
7. WD_BLACK SN850X 2TB: Most Versatile for Gaming Builds
- 7300MB/s read and 6300MB/s write
- Integrated heatsink prevents throttling under load
- Game load times match a console's own drive
- Drops into PS5 and desktop M.2 slots
- 4.8 stars across more than 15000 reviews
- No mounting screw included
- Heatsink can conflict with motherboards that ship their own
- Listing notes a newer generation exists
Owners of this drive mostly installed it for one reason: to stop thermal throttling. The integrated heatsink is the whole point, and reviewers report no throttling behaviour under sustained load, with read and write speeds holding above 7000MB/s in real-world use.
It is also the most flexible of the console-friendly picks. Because it is a standard M.2 2280 card with a cooler attached, the same drive serves a PS5 expansion bay, a gaming desktop and a workstation.
Check clearance before you buy. On a motherboard that ships with its own M.2 heatsink, the included one may not have room, and some owners hit exactly that. The missing mounting screw is a small fix but worth knowing about in advance.
Compared with the WD_BLACK SN850P 2TB, the heatsink here is a desktop design rather than a console-specific one, so it fits more machines and suits a build rather than a single console.
8. Samsung 990 EVO Plus 1TB: Budget Pick at 1TB
Samsung SSD 990 EVO Plus 1TB, PCIe Gen 4×4 | 5×2 M.2 2280, Up to 7,150 MB/s
- 7150MB/s read and 6300MB/s write
- Nickel-coated controller runs cool and draws less power
- Also works in PCIe 5.0 x2 platforms
- Magician keeps firmware and health current
- Lowest listed price of the drives compared here
- Only 1TB which feels tight for a large game library
- Headline speeds need a compatible M.2 slot
This is the entry point for a first SSD purchase. The headline numbers are close to the flagships, and the nickel-coated controller keeps power draw and thermals modest, which matters most in a laptop.
It also runs in PCIe 5.0 x2 hosts, so a machine without a full x4 Gen5 slot can still use it at close to its listed speed. That single detail makes it more broadly usable than the generation number suggests.
The honest limitation is 1TB. For a working drive that holds an operating system, applications and a handful of games, that is fine. For a console or a gaming PC where you want to stop deleting titles, it fills quickly, and the 2TB options here suit that better.
Owners rate it 4.8 stars, and the recurring theme is quiet, cool, uneventful operation. That is a good quality in a drive you will forget exists.
9. WD_Black SN7100 2TB: Best for Handheld Gaming PCs
- 7250MB/s read and 6900MB/s write
- Up to 35% faster than the prior generation
- Up to 100% better power efficiency for portable builds
- Low-profile single-sided design fits handheld slots
- Next-generation TLC 3D NAND
- 3-year warranty is shorter than premium rivals
- Dashboard utility is Windows-only
- Listing notes a newer generation exists
Steam Deck, ROG Ally and Legion Go owners have a habit of buying a small card, hitting the wall, and replacing it with 2TB. This is that card, and the reason it works is efficiency rather than raw speed. The manufacturer claims up to 100% better power efficiency than the previous generation, which in a handheld translates directly into longer sessions.
The low-profile single-sided board is 0.04 inches thick in the listing, which is what clears the tight slots in most handheld shells. Owners report fast load times and easy installation with no adapter needed.
TLC NAND is a step up from the QLC in the WD Green SN350, and it matters when a handheld library is written to constantly as you install, update and delete. That extra endurance is the reason this drive outranks the cheaper option here despite a 3-year warranty.
The drive optimisation utility is Windows-only, so do not expect an equivalent tool from a handheld operating system.
10. Crucial T500 2TB: Best for Sustained Writes
- 7400MB/s read and 7000MB/s write
- 1.18M read and 1.44M write IOPS
- TLC NAND holds up under long write sessions
- Up to 16% faster game loads with DirectStorage
- Boosts creative app performance by up to 42%
- Needs a compatible PCIe Gen4 M.2 slot
- Bundled software is time-limited rather than permanent
Sustained writing is where budget drives give up, and TLC NAND is the fix. The T500 pairs 7400MB/s read with 7000MB/s write and holds that write figure far longer than a DRAM-less or QLC card, which is exactly the behaviour a project drive needs.
Owners use it for rendering and timeline work and report that creative applications open and respond faster than on their previous drive. Random performance is strong too, at 1.18M read and 1.44M write IOPS, which is what keeps multitasking responsive while an export runs.
Two things to know. The bundled Acronis True Image and the one-month Adobe Creative Cloud subscription are useful for a first migration, but the creative subscription is a trial rather than a permanent addition to the price. And the drive needs a Gen4 M.2 slot to deliver these numbers.
Against the Samsung 990 PRO 2TB, the T500 is arguably the better creative drive because of the TLC endurance, even though raw read speed is marginally lower.
11. Samsung 9100 PRO 2TB: Best for PCIe 5.0 Builds
Samsung SSD 9100 PRO 2TB, PCIe 5.0×4 M.2 2280, Up to 14,700MB/s
- 14700MB/s read and 13400MB/s write
- 1.85M read and 2.6M write IOPS
- 5nm controller up to 49% more power efficient
- Lineup runs up to 8TB
- Magician covers firmware encryption and health
- Needs a PCIe 5.0 x4 host and real cooling to hold full speed
- Gen5 heat and power can strain laptop and console chassis
The fastest drive in this comparison, and the one most people do not need. At 14700MB/s read and 13400MB/s write it roughly doubles the 990 PRO, and the random figures are the more interesting number for anyone running AI workloads or heavy multitasking.
If you have a current platform with a PCIe 5.0 x4 slot, this is the drive that actually uses it. On anything older it will run at the speed your slot allows, which means a Gen5 drive in a Gen4 machine is money spent on a number you will never see.
Owners point to the 5nm controller as the real improvement, with power efficiency up to 49% better than the 990 PRO, plus the warranty and Magician software that Samsung keeps current across the lineup. The consistent caveat is cooling, and heat is the reason a Gen5 card is a poor fit for a laptop or a console.
Our take: if your motherboard has a Gen5 M.2 slot and you work with very large files, this is the pick. Otherwise the Gen4 drives here deliver nearly all of the real-world benefit for a lot less.
12. WD Blue SA510 4TB: Best for Legacy PC Upgrades
Western Digital 4TB WD Blue SA510 Internal Solid State Drive SSD – SATA III 6 Gb/s, 2.5″/7mm, Up to 560 MB/s – WDS400T3B0A
- 4TB in a thin 7mm 2.5-inch body
- 560MB/s read and 520MB/s write
- No moving parts so it shrugs off shocks
- 5-year limited warranty
- Data recovery service included
- SATA III throughput far below any NVMe option
- 4.4 average rating is the lowest here
- Not suited to write-intensive or high-endurance work
A thin 2.5-inch SATA drive with 4TB inside it solves a specific and unglamorous problem: an older desktop or laptop that has a SATA bay and no usable M.2 slot. The 7mm body fits places a thicker 2.5-inch drive will not.
This is the pick on our list with the lowest average rating, at 4.4 stars, and the reviews explain why. Owners running it as long-term bulk storage report reliability complaints, and roughly a tenth of its ratings sit at one star. Treat it as storage for files you can rebuild, not as a system drive you depend on.
Where the Crucial BX500 4TB covers the same territory better: it carries a 4.8 average on a far larger review base, ships with cloning software, and stays in the same speed class. If both fit your machine, the BX500 is the safer purchase.
Good to know: the 5-year warranty is longer than most rivals in this class, so the manufacturer is not treating it as a disposable drive even if owner reviews are mixed.
How to Choose SSDs During Prime Big Deal Days
Capacity and Intended Workload
Capacity decides the drive before speed does. 1TB is a working drive for an operating system, applications and a few games; 2TB is the practical minimum for a gaming library you do not want to manage; 4TB is for large media collections and consoles that have outgrown two expansions.
Match the tier to the job. A compact system drive can be small, a general-purpose upgrade should be 1TB or 2TB, and a games-and-archive machine should start at 2TB and go higher if the slot exists.
Interface and Device Compatibility
SATA and NVMe are not interchangeable, and neither are PCIe generations. A SATA drive tops out near 560MB/s; a PCIe 4.0 NVMe drive reaches roughly 7000MB/s, and a PCIe 5.0 drive doubles that again.
Check the slot before you buy. A Gen4 drive works in a Gen3 slot but runs at the Gen3 limit, and a Gen5 drive in a Gen4 slot behaves like an expensive Gen4 drive. The Crucial P310 2TB is a safe middle ground because it is backward compatible with Gen3 platforms.
Sustained Speed Versus Short-Burst Performance
Headline sequential numbers are measured on an empty drive in ideal conditions. Sustained speeds drop once the write cache fills, and the gap between the two is widest on DRAM-less and QLC drives.
For gaming and general use, the burst figure tells you most of the story. For an hour-long export or a scratch drive, look at NAND type instead: TLC like the Crucial T500 2TB holds write speed far longer than QLC.
Endurance, Thermal Design, and Warranty
Endurance is measured in terabytes written, and it matters most on the largest capacities, where a full rewrite of the drive happens more often. A 3-year warranty on a 4TB card is a weaker signal than a 5-year warranty on the same capacity.
Thermal design matters wherever airflow is poor. A Gen5 drive in a laptop or a console needs a heatsink and room around it, while a value Gen4 card in a desktop with a board heatsink is usually fine on its own.
Form Factor and Upgrade Fit
Most modern drives are M.2 2280, roughly 22mm by 80mm, and they fit most desktop and laptop slots. Handhelds want the short M.2 2240 or a single-sided 2280 card, and a double-sided board simply will not fit in a thin chassis.
SATA drives come as 2.5-inch or mSATA. A 7mm-thick 2.5-inch drive fits older laptops that cannot take a thicker body, and a desktop needs the SATA data cable and power lead as well as a free bay.
How to Shop SSD Deals During the Sale
Read the listing rather than the badge. Confirm the exact model number, because a 2TB and a 1TB card in the same family share a name and not a price. Check the capacity, interface and form factor against your machine, and read what ships in the box, since a bare card and a heatsinked card are different products.
Look at who sells and who ships the drive, whether the listing is new or renewed, and what the warranty covers. Most offers on this event need an active Prime membership, and the deal mix changes through the two days.
- Confirm the model number and capacity match your machine.
- Verify the interface, SATA or NVMe, and the PCIe generation of your slot.
- Check the form factor against your clearance, especially in a handheld.
- Read whether the listing is new or renewed and who ships it.
- Compare the sale figure against a price history for that exact model before assuming a discount.
- Confirm a heatsink is included if your slot has no cooling of its own.
Frequently Asked Questions
When does Amazon Prime Big Deal Days run in 2026?
Amazon’s autumn Prime event runs October 6-7, 2026. Storage is one of the categories where deal coverage tends to be deepest, with NVMe cards, console expansion drives and SATA models all appearing. Most offers require an active Prime membership, and a free trial counts. The mix changes through the event, so check the listing rather than relying on a published deal list.
Do you need Prime to buy an SSD during Prime Big Deal Days?
Most offers during the event require an active Prime membership, though a free trial covers you for its length. A small number of offers run for everyone. If you already subscribe, storage is a category where the event is worth your attention because the higher-capacity NVMe tiers are the ones that actually move.
Do SSDs usually get meaningful discounts during Prime Big Deal Days?
It depends on the tier. High-capacity NVMe drives and the top PCIe generations are the ones that tend to move, while entry SATA models often sit at their normal street price through the whole event. The more useful check is comparing the sale figure against a price history for the exact model number, because the reference price on a listing is not always a real previous price.
Is a 1TB SSD enough for gaming and everyday use?
Yes, for a single machine running an operating system, applications and a handful of games. You will fill it faster than you expect once a few large titles install, and constant deleting and rewriting is also what wears a smaller drive out. For a console or a gaming PC, 2TB is the practical starting point and 4TB is where the pressure disappears.
How do I know whether an SSD will work with my computer?
Check three things before you buy: whether the machine has an M.2 NVMe slot or only SATA connectors, what PCIe generation that slot runs, and how much clearance the chassis has. A PCIe 4.0 drive works in a Gen3 slot at reduced speed, and a double-sided card will not fit every laptop or handheld.
Should I buy a new or renewed SSD during the sale?
For a system drive, buy new. A renewed card carries a shorter warranty and no predictable endurance history, and a failed boot drive costs far more time than the saving is worth. Renewed listings can make sense for bulk storage you can rebuild from a backup, provided the warranty terms are clear.
Final Verdict: Best Amazon Prime Big Deal Days SSD Deals
Buy the Crucial BX500 4TB if you want the most storage and the most proven reliability per unit of money, and you are upgrading a SATA machine or filling a data-heavy drive. It is the pick with the deepest owner review base in this comparison and the rating to match.
If your budget is tighter, the Samsung 990 EVO Plus 1TB is the one to watch: near-flagship sequential speeds, a cool-running controller and a 5-year warranty at the lowest listed figure of the twelve. For a console, the WD_BLACK SN850P 2TB removes every compatibility question.
For gaming PCs the WD_BLACK SN850X 2TB covers a console, a desktop and a workstation with one card. For handhelds the WD_Black SN7100 2TB is the low-profile TLC option. For video and creative work the Crucial T500 2TB holds write speed longer than anything cheaper here, with the Samsung 990 PRO 2TB as the alternative if software support matters more to you. Older PCIe 3.0 machines get the WD Green SN350 2TB, and a Gen5 platform gets the Samsung 9100 PRO 2TB.
Whatever you settle on, check the model number against your slot and look at the price history before you assume a saving is real.
