Our take on the WD Blue SN5100 4TB NVMe M.2 2280 Internal SSD

The WD Blue SN5100 is a 4TB PCIe Gen 4.0 NVMe drive in the standard M.2 2280 size. WD rates sequential reads up to 6,900MB/s, which puts it among the faster Gen 4 drives and well ahead of older Gen 3 models. The 4TB capacity suits game libraries, video projects and large photo catalogs on a single drive. It is a mainstream, value-focused line rather than WD's premium Black series, so shoppers comparing it with Samsung 990 Pro or WD Black SN850X should expect similar everyday speed but less top-end sustained performance and no heatsink.

Pros

  • PCIe Gen 4.0 with reads up to 6,900MB/s
  • Fits most modern laptops and desktops with an M.2 slot
  • WD's established reliability and firmware support
  • Power-efficient design suited to laptops
Cons
  • No heatsink included; sustained writes can slow without airflow
  • DRAM-less design can trail premium Gen 4 drives under heavy mixed loads

  • Not aimed at workstation-level endurance

Questions and answers

Is the WD Blue SN5100 a good upgrade from a SATA SSD?
Yes. Moving from SATA to PCIe Gen 4 NVMe cuts boot and load times noticeably, and the 4TB size means fewer drives to manage. The gain is largest on a motherboard with a Gen 4 x4 slot.
Does it come with a heatsink?
No. It is a bare M.2 2280 drive, so a desktop or PS5-style install that needs cooling should use the motherboard or third-party heatsink.
Will it work in a PCIe Gen 3 laptop?
It fits any M.2 2280 slot that supports NVMe, but on Gen 3 the drive runs at Gen 3 speeds, well below its rated 6,900MB/s reads.
How does it compare with the WD Black SN850X?
The Black SN850X is WD's premium gaming drive with higher sustained performance and optional heatsink versions. The Blue SN5100 targets everyday use and bulk capacity at a lower tier.
Is 4TB enough for games and video?
For most people, yes. Modern games run 50–150GB each and 4K video eats space fast, so 4TB holds a large library without constant cleanup.
What is in the box?
The drive itself. No cable, screw or heatsink is included, so check your system's mounting hardware before installing.
Where is the WD Blue SN5100 4TB NVMe M.2 2280 Internal SSD cheapest?
