WD Blue SN550 250GB NVMe SSD (WDS250G2B0C) – PCIe Gen3 x4 M.2 2280, Up to 2,400MB/s

An affordable NVMe boot drive with four times the read speed of SATA.

The WD Blue SN550 250GB is a PCIe Gen3 x4 NVMe M.2 2280 SSD designed as an affordable boot drive for desktops and laptops. With reads up to 2,400MB/s, a 150 TBW endurance rating and low power draw, it gives everyday users and system builders a responsive NVMe upgrade.

Why an NVMe Boot Drive Is the Smart Budget Upgrade

Many systems with M.2 slots still boot from SATA drives or hard drives, leaving available PCIe bandwidth unused. Boots, updates and app launches take longer than necessary.

The SN550 uses that M.2 slot to deliver up to 2,400MB/s at a budget-friendly price. As a dedicated boot drive, 250GB holds the OS and core apps, while large files can stay on a secondary drive.

Fast NVMe Responsiveness

Sequential reads of up to 2,400MB/s and random reads of up to 165K IOPS make Windows boot quickly and keep everyday apps snappy.

Efficient, Cool and Reliable

The SN550’s WD in-house controller and low-power design suit laptops and small form factor PCs. It is rated for 150 TBW and 1.75 million hours MTTF.
