A fast 2 TB drive costs about $255 today. The same class of drive sold for about half that a year ago, because the shortage that took DDR5 memory to four times its 2025 price took NAND flash with it.
SSD increases have flattened. TrendForce forecast NAND contract prices up 55% to 60% in the first quarter of 2026 and 70% to 75% in the second, then 10% to 15% in the third, and reported that PC makers had built enough inventory that suppliers turned flexible on client SSD pricing. Memory is still climbing. Storage has flattened at a higher level.
Buy the capacity you need, at Gen4 speed, and put nothing extra into sequential numbers you will not notice. A game loads off a 7,100 MB/s drive and a 14,700 MB/s drive within a second of each other, and the faster one costs $145 more.
Crucial P310 2 TB (PCIe Gen4 NVMe, M.2 2280)
PCIe Gen4 · up to 7,100 MB/s read · 6,000 MB/s write · M.2 2280 · Micron G8 NAND
Two terabytes at $255 is the best price per terabyte we found from a major brand, with 11,153 ratings behind it. It reads at up to 7,100 MB/s, which is as much sequential speed as a game or a project folder can use, and it is the drive to put in a desktop, a laptop or a handheld.
- The cheapest 2 TB from a major brand in this sweep, at $128 per terabyte
- Crucial is Micron's consumer brand, so the NAND comes from the company that makes it
- Crucial lists the ROG Ally X, Legion Go and AYANEO Kun as compatible, so it fits a handheld
- Backward compatible with Gen3 boards, which keeps it useful in an older machine
- The cheapest offer ships from Amazon's German store, so check the delivery date before ordering
- Write speed of 6,000 MB/s trails the 990 Pro, which matters for sustained large copies
- No heatsink in this version, so a PS5 needs the heatsink model in Pick III
Crucial sells the P310 as a mainstream Gen4 drive, and in a market where a 2 TB Samsung 990 Pro costs $390, mainstream is the right place to shop. The gap between the two is 350 MB/s of rated read speed and $135.
The flagship earns its price on sustained writes. Copying a 200 GB video project lands the flagship ahead; loading a level, booting Windows or opening Photoshop does not. Buy the P310 for a gaming or general build and spend the difference on memory, which is the part of the 2026 build that hurts.
Check one thing on the listing. The $255 offer comes from Amazon's German storefront. The seller is Amazon, so the thing to check is the delivery estimate.
WD_Black SN7100 1 TB (PCIe Gen4 NVMe, M.2 2280)
PCIe Gen4 · up to 7,250 MB/s read · 6,900 MB/s write · TLC 3D NAND · M.2 2280
The SN7100 is the drive to buy when a terabyte is enough. It is sold and shipped by Amazon at $195, carries 6,515 ratings at 4.8 stars, and SanDisk built it around power efficiency, which is what a laptop or a handheld needs from storage.
- Sold and shipped by Amazon, with the largest rating count of any drive here
- SanDisk claims up to 100% better power efficiency than the previous generation, which shows up as battery life
- Writes at 6,900 MB/s, close to its read speed, so large copies stay fast
- Single-sided M.2 2280, so it fits thin laptops and handhelds
- $195 per terabyte is a worse rate than the 2 TB P310's $128
- SanDisk has replaced it with the Optimus GX 7100, so this SKU is on its way out
- No heatsink, which a PS5 requires
SanDisk says on the listing that this product has been replaced by the SanDisk Optimus GX 7100. The WD_Black, WD Blue and WD Green flash lines are now made by SanDisk and sold under license from Western Digital, and SanDisk is moving them to its own Optimus branding.
For a buyer that means two drives sit side by side. The SN7100 at $195 has six thousand more ratings and Amazon as the seller. The Optimus GX 7100 at $199 is the same class of drive with 89 ratings. Buy the SN7100 while the stock lasts. The Optimus is the same class of drive under a new name.
One terabyte is tight in 2026 if you install a lot of games, so take this pick for a laptop, a second drive or a handheld, and take the 2 TB P310 for a desktop.
Crucial P310 1 TB with Heatsink (PCIe Gen4 NVMe, PS5)
PCIe Gen4 · up to 7,100 MB/s read · 6,000 MB/s write · heatsink installed · M.2 2280
A PS5 needs a Gen4 M.2 drive with a heatsink that clears the console's bay, and Crucial names the PlayStation 5 on the listing. At $189 with the heatsink attached, this is the cheapest way to double a PS5's storage from a brand you have heard of.
- Crucial lists PlayStation 5 compatibility on the product page
- The heatsink is fitted, which saves buying and attaching one
- 7,100 MB/s read clears the 5,500 MB/s Sony asks for
- Sold by Amazon, from the Crucial store
- $189 per terabyte, so a 2 TB drive plus a separate heatsink can work out cheaper
- A PS5 install means removing the console's side panel and a screwdriver
- Games still have to be moved by hand in the console's storage menu
Sony asks for a PCIe Gen4 M.2 drive reading at 5,500 MB/s or better, with a heatsink, in the 2230 to 22110 range. This drive meets all of it and arrives with the heatsink already on, which is the part people get wrong when they buy a bare drive and a cooler separately.
If you want 2 TB in a PS5 instead, the bare P310 in Pick I plus an aftermarket heatsink costs less per terabyte than a 2 TB heatsink SKU. That route costs you ten minutes and the risk of mounting it badly. For most people, one terabyte fitted and finished is the better trade.
WD Blue SN5100 4 TB (PCIe Gen4 NVMe, M.2 2280)
PCIe Gen4 · up to 6,900 MB/s read · M.2 2280 · SanDisk 3D CBA NAND · 5-year warranty
Four terabytes at $480 works out to $120 per terabyte, the lowest rate of any drive here. It is sold and shipped by Amazon, rates 4.8 stars, and it is the drive for a machine that stores video projects, a game library that never gets uninstalled, or local AI models.
- Cheapest price per terabyte here, and capacity is where the shortage hurts most
- Sold and shipped by Amazon
- Five-year limited warranty from SanDisk
- One 4 TB drive keeps a second M.2 slot free, which matters on boards that share lanes
- 6,900 MB/s is below the 1 TB and 2 TB versions of the same family
- $480 in one purchase, against $255 for the 2 TB P310
- Also being replaced, by the SanDisk Optimus 5100
Capacity is the part of a build the NAND shortage punished hardest, because a 4 TB drive holds four times the flash at a moment when flash is what costs money. Paying $120 per terabyte for that capacity is the best rate on this page, and a single large drive beats two smaller ones on most boards, where the second M.2 slot borrows lanes from the graphics card or the chipset.
As with the SN7100, the listing says SanDisk has replaced this line with the Optimus 5100. The 2 TB Optimus 5100 sells for $299 with 148 ratings, so at 4 TB the older SKU is the one with the track record.
Samsung 9100 Pro 2 TB (PCIe Gen5 NVMe, M.2 2280)
PCIe 5.0 x4 · up to 14,700 MB/s read · 13,400 MB/s write · 1,850K/2,600K IOPS · M.2 2280
The 9100 Pro reads at up to 14,700 MB/s, double any Gen4 drive here, and costs $400 for 2 TB against the P310's $255. Buy it when you move very large files for a living. For gaming, the extra $145 buys a bigger number on the box and the same wait.
- The fastest sequential speeds available in a consumer M.2 drive
- Samsung rates random performance at 1,850K read and 2,600K write IOPS, which is what heavy multitasking uses
- A 5 nm controller that Samsung says is up to 49% more power efficient than the 990 Pro
- Sold and shipped by Amazon
- $200 per terabyte, the most expensive rate here
- Needs a Gen5 M.2 slot, which many boards give only to the top socket
- Gen5 drives run hot enough that some boards want their heatsink fitted
- Game load times are within about a second of a good Gen4 drive
Gen5 earns its price in one place: moving very large files, repeatedly. Video editors pulling 8K footage off a drive, people shuffling 50 GB AI model files, and anyone whose day includes a progress bar longer than a minute will feel the difference.
Games will not. DirectStorage reads assets in small chunks, and the bottleneck sits in decompression and the CPU. Reviewers keep measuring Gen5 drives within about a second of Gen4 drives on level loads.
If your board has a spare Gen5 slot and your work is file-heavy, this is the drive. Otherwise take the P310 and the $145.

Four more worth knowing.
Samsung 990 Pro 2 TB
The Gen4 flagship, at $390 against the P310's $255 for the same 2 TB. It reads at up to 7,450 MB/s and holds its write speed better on long copies, and it carries 13,353 ratings. Worth the premium if you write large files all day and your board has no Gen5 slot.

Buy capacity first
Storage prices now scale with capacity, so the question is how many terabytes you need. A 2026 AAA install runs 100 to 150 GB, so 1 TB holds around ten games plus Windows, and 2 TB is the comfortable floor for a gaming desktop. Read speed above 7,000 MB/s changes nothing you can feel in a game.
Gen4 or Gen5
Gen5 doubles the sequential numbers and costs about 55% more per terabyte. It pays off when you move very large files repeatedly: 8K video, large AI model files, disk images. It does not pay off for gaming, where loads land within about a second of a Gen4 drive because decompression and the CPU set the pace. Check your motherboard too, since most boards wire only the top M.2 slot for Gen5.
What a PS5 needs
Sony asks for a PCIe Gen4 M.2 NVMe drive reading at 5,500 MB/s or faster, sized 2230 to 22110, with a heatsink that clears the bay. Drives sold with a heatsink fitted, like Pick III, remove the guesswork. A bare drive plus an aftermarket heatsink is cheaper per terabyte at 2 TB, if you are comfortable fitting it.
Where the price went
NAND flash rose with DRAM through 2026 as makers moved capacity toward server and AI products. TrendForce forecast NAND contract prices up 55% to 60% in the first quarter and 70% to 75% in the second, and client SSD contract prices up at least 40% in the first quarter alone. By the third quarter that had slowed to 10% to 15%, with suppliers turning flexible on client SSD pricing because PC makers had already stocked up. Storage has found a plateau. Memory has not.
Skip these upgrades for now
An 8 TB consumer M.2 drive costs more per terabyte than two 4 TB drives. A Gen5 drive in a Gen4 slot runs at Gen4 speed. A second drive bought to split games from Windows costs performance on boards that share lanes between the second M.2 slot and the graphics card. And a DRAM-less drive with a good host memory buffer, which is what most drives here use, is fine for everything short of sustained professional writes.
FAQ.
Two terabytes for a gaming desktop, one for a laptop or a second drive, four if you keep video projects or local AI models. A current AAA game installs at 100 to 150 GB, so a 1 TB drive holds about ten of them alongside Windows.
No. Game loads land within about a second of a good Gen4 drive, because decompression and the CPU set the pace. Gen5 is worth its premium for repeated large file transfers: 8K video, AI model files, disk images.
Memory makers moved production capacity toward server and AI products, which took NAND flash with it. TrendForce forecast NAND contract prices up 55% to 60% in the first quarter of 2026 and 70% to 75% in the second. The third quarter slowed to 10% to 15%, so storage has flattened while DDR5 keeps climbing.
Not to 2025 levels soon. The increases have stopped, and they have not reversed. TrendForce noted that PC makers built inventory through the first half of 2026, which pushed suppliers to price client SSDs flexibly. A flat market is the realistic best case for the rest of the year.
A PCIe Gen4 M.2 NVMe drive rated at 5,500 MB/s or faster, in an M.2 2230 to 22110 size, with a heatsink. Pick III ships with the heatsink fitted and Crucial names the PS5 on the listing.
No, for ordinary use. Most mainstream drives now borrow a slice of system memory through the host memory buffer, and the difference shows only in sustained heavy writes. A professional moving hundreds of gigabytes a day should buy a drive with its own DRAM, like the 990 Pro.
Most builds: Crucial P310 2 TB at $255.
Laptops: WD_Black SN7100 1 TB at $195.
PS5: P310 1 TB with heatsink at $189.
Big libraries: WD Blue SN5100 4 TB at $480.
Storage doubled in price this year and then stopped moving, which makes it the one part of a 2026 build you can buy without watching the market. Take the 2 TB P310 at $255 for a desktop, the SN7100 for a laptop, the heatsink P310 for a PS5, and the 4 TB SN5100 when the library is the point. Leave Gen5 to people who move very large files for a living, and put the money you saved toward memory, where the prices are still going up.
