WD_BLACK SN770 1TB NVMe SSD

The WD_BLACK SN770 is a 1TB M.2 2280 internal SSD built for consumers who want faster game loads and responsive streaming. It uses a PCIe Gen4 x4 interface with NVMe protocol and TLC memory to deliver up to 5150 MB/s sequential read and 4900 MB/s sequential write speeds. Random performance reaches 740000 IOPS read and 800000 IOPS write for snappy multitasking.

DRAM-less design with HMB caching

The drive operates without a dedicated DRAM cache, relying on Host Memory Buffer support from the platform to maintain low latency. Its M.2 2280 form factor fits standard motherboard slots and runs within a 0°C to 85°C operating range while drawing only 65 mW active power. The PCIe Gen4 link is backward compatible with Gen3 systems for broad platform support.

Check motherboard M.2 slot and OS support

Verify your board has an M.2 2280 slot wired for PCIe NVMe and confirm whether it runs at Gen4 or Gen3 speeds. Windows is required for the WD_BLACK Dashboard monitoring and gaming-mode optimisation tools. The drive is rated for 600 TBW endurance and a 1.75 million hour MTTF for long-term reliability.

Questions about this item

What PCIe Gen4 lane count does the WDS100T3X0E use and what sequential read speed does that support?

The drive runs on up to four PCIe Gen4 lanes and delivers up to 5150 MBps sequential read.

What M.2 form factor and length must the motherboard slot accept for this 2280 drive?

The SSD uses the M.2 2280 form factor, so the slot must accommodate an 80 mm long module.

How is the drive installed and which step do builders often miss?

Insert the module at an angle into the M.2 slot, press it flat, and secure it with the motherboard screw; the step often missed is fastening that screw.
