Samsung 990 Pro M.2 4 Tb Pci Express 4.0 V-Nand TLC Nvme, W128825757 (4.0 V-Nand TLC Nvme)

Samsung 990 Pro M.2 4 Tb Pci Express 4.0 V-Nand TLC Nvme, W128825757 (4.0 V-Nand TLC Nvme)

Bottom line: The Samsung 990 Pro M.2 4 Tb Pci Express 4.0 V-Nand TLC Nvme: 4TB in a single M.2 slot, enough for a full game library or large media archive; main trade-off: PCIe 4.0 only, so it will not use the extra bandwidth of a Gen5 M.2 slot.

Pros & Cons

Pros

  • ✓ 4TB in a single M.2 slot, enough for a full game library or large media archive
  • ✓ PCIe 4.0 NVMe interface gives far more bandwidth than SATA SSDs
  • ✓ V-NAND TLC flash, generally more durable under heavy writes than QLC drives
  • ✓ Mounts directly to the board with no SATA power or data cables
  • ✓ Backward compatible with PCIe 3.0 M.2 NVMe slots, at lower bandwidth

Cons

  • ✗ PCIe 4.0 only, so it will not use the extra bandwidth of a Gen5 M.2 slot
  • ✗ Will not work in M.2 slots that support SATA only
  • ✗ Listing does not say whether a heatsink is included
  • ✗ Listing title includes a seller code (W128825757), so confirm the exact variant

Manufacturer description

The Samsung 990 Pro puts 4TB of V-NAND TLC flash on a single M.2 NVMe SSD that runs over PCIe 4.0. That is enough room for a large game library, video project archives or a collection of local AI models on one drive. The M.2 drive mounts directly on your motherboard, so there are no SATA data or power cables to route. It suits compact desktops and any laptop or small-form-factor PC with a free M.2 NVMe slot. Because it uses NVMe over PCIe 4.0, it runs at full interface speed in a Gen4 M.2 slot. It also works in PCIe 3.0 slots at lower bandwidth, and in PCIe 5.0 slots at Gen4 speed. Samsung's…

SpecPicks Verdict

SpecPicks scored Samsung 990 Pro M.2 4 Tb Pci Express 4.0 V-Nand TLC Nvme using a rating × review-volume × price-fit model applied to published specs and reviews across the ssds & storage category. Compare with similarly-priced alternatives in the ssds & storage category before committing. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for ssds & storage of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions

How much storage does the Samsung 990 Pro in this listing have?

This listing is for the 4TB version of the Samsung 990 Pro, an M.2 NVMe SSD built with Samsung V-NAND TLC flash.

Will the Samsung 990 Pro 4TB work in my PCIe 3.0 motherboard?

Yes, if the M.2 slot supports NVMe. It is a PCIe 4.0 drive, so in a PCIe 3.0 slot it runs at Gen3 bandwidth, which is lower than its full Gen4 speed.

Does this SSD fit an M.2 slot that only supports SATA?

No. The 990 Pro is an NVMe drive and needs an M.2 slot wired for PCIe NVMe. Check your motherboard or laptop manual to confirm the slot supports NVMe before you buy.

Can I use the Samsung 990 Pro 4TB in a PS5?

The PS5 expansion slot accepts PCIe 4.0 M.2 NVMe SSDs, which this drive is. Sony recommends using a heatsink, and this listing does not say whether one is included, so check the variant details before you buy.

What does V-NAND TLC mean for this drive?

TLC flash stores three bits per cell in Samsung's stacked V-NAND. Compared with QLC flash, TLC generally gives steadier sustained write speeds and higher endurance. Check the manufacturer's listing for the exact endurance (TBW) rating and warranty terms.
