WD Blue 3D NAND 250GB M.2 2280 SATA SSD

This Western Digital drive is a 250GB internal solid-state drive built on 3D NAND technology. It uses the SATA III interface in an M.2 2280 form factor. The drive targets everyday computing workloads such as booting an operating system, launching applications and storing documents. Sequential reads reach up to 550 MB/s and sequential writes up to 525 MB/s.

Upgrade from a mechanical hard drive or early SSD

Replacing a traditional 2.5-inch hard drive with this SSD removes moving parts and delivers much faster random access. The jump is worth it when a system feels sluggish during start-up or when opening large files. Random read performance reaches 95,000 IOPS and random write reaches 81,000 IOPS. The 1.75M hour MTTF and 100 TBW rating indicate a durable step up from older storage.

Fits any M.2 2280 SATA slot with low power draw

The drive slots directly into a motherboard or laptop M.2 key-M socket wired for SATA. It draws 52 mW average active power and as little as 5-7 mW in DEVSLP idle state. This low consumption helps extend battery life in portable machines. WD F.I.T. Lab certification confirms broad compatibility. Free downloadable software adds drive monitoring and cloning tools.

Questions about this item

What motherboard slot and length does the M.2 2280 form factor require?

The drive fits a standard M.2 2280 slot, meaning it needs an M.2 key‑M or key‑B socket that accepts 80 mm long modules.

How is the WD Blue 250GB SSD installed, and what step do builders often miss?

Insert the drive at an angle into the M.2 socket, press it flat, and secure it with the single mounting screw; many forget to fasten that screw, leaving the drive unsecured.

What software maintenance does the drive need over its life?

Download the free WD Dashboard to monitor SMART health, track the 100 TBW endurance rating, and apply firmware updates when released.
