250GB PCIe Gen4 NVMe SSD

The WD_BLACK SN770 NVMe SSD in M.2 2280 form factor delivers 250GB of storage for consumer desktops and laptops. A PCIe Gen4 16GT/s interface with up to four lanes provides sequential reads up to 4000 MBps and writes up to 2000 MBps. Random performance reaches 240,000 read IOPS and 470,000 write IOPS.

Low 65mW active power and 0–85°C operation

Active power draw is rated at 65mW, helping keep system thermals manageable during extended sessions. The controller operates across a 0°C to 85°C range, while the drive withstands storage temperatures from -40°C to 85°C. Advanced thermal management technology maintains consistent throughput without adding acoustic noise.

M.2 2280 slot with PCIe Gen4 support required

Installation requires an M.2 2280 slot wired for PCIe Gen4 x4 to achieve full speed, though the interface remains backwards-compatible with PCIe Gen3 platforms. The slim single-sided design fits tight clearances in compact chassis and leaves motherboard expansion slots unobstructed. A 200 TBW endurance rating and 1.75 million-hour MTTF support long-term gaming workloads.

Questions about this item

Will this M.2 2280 drive fit in a laptop slot that only has room for a single-sided board?

The drive uses the standard M.2 2280 form factor. You should verify your laptop's slot clearance and keying matches this physical size before purchase.

My motherboard only supports PCIe Gen3. Will I still get the advertised 4000 MBps read speed?

The drive is backwards-compatible with PCIe Gen3, but sequential read speeds will be limited to the Gen3 interface maximum, below the stated 4000 MBps.

Is the 200 TBW endurance rating sufficient for a primary gaming and OS drive?

At 200 TBW, the drive is rated for substantial write workloads. Typical gaming and OS use writes far less data daily, so endurance should last many years.
