Our verdict

Strong raw speed for a desktop NVMe upgrade, but check current-generation status first since WD lists this model as succeeded by a newer drive.

Overview

This WD_BLACK drive packs 2TB into the M.2 2280 form factor with an attached heatsink, rated up to 7,300MB/s read and 6,300MB/s write. It's aimed at desktop gaming builds and workstations with a free PCIe Gen4 slot.

The heatsink is built into this version, which matters for sustained transfers since NVMe drives at this speed class throttle under heat without one, though it also means the drive will not fit in a slot with limited clearance, like most laptops or a console bay with its own cooling cover. Worth flagging directly from the listing: WD states this specific model has been succeeded by a newer generation drive from the SanDisk lineup, so buyers should confirm they are getting the SN850X rather than assuming it's the current flagship.

  • 2tb capacity, m.2 2280 form factor
  • Up to 7,300 mb/s read, 6,300 mb/s write
  • Heatsink attached for sustained transfer speeds
  • Built for gaming pc and workstation upgrades

Who it's for

A desktop gaming build or workstation with a free PCIe Gen4 M.2 slot is where this drive belongs, including as a PS5 expansion drive if the heatsink clears the console's bay. Anyone wanting WD's current flagship model specifically should check generation status first, since the listing marks this one as replaced.

Pros and cons

Pros
  • High rated read/write speeds for a gaming pc or workstation
  • Heatsink attached, no separate cooling purchase needed
Cons
  • Heatsink height won't clear most laptop m.2 slots
  • Wd lists this exact model as replaced by a newer generation

Performance notes

Rated speeds reach up to 7,300MB/s read and 6,300MB/s write in the M.2 2280 form factor, with the attached heatsink helping the drive hold those speeds during longer sustained transfers instead of throttling. Because the heatsink is fixed to the drive, it needs a slot with enough clearance, which rules out most laptops and some console expansion bays with their own cooling covers.
