What the Blue SN550 NVMe is

This internal SSD uses a PCI-Express 3.0 x4 interface and 3D NAND to deliver 250GB of consumer storage. It suits builders who want faster boot and load times without moving to a higher-priced tier. The single-sided M.2 2280 form factor fits most modern motherboards and compact laptops. No moving parts means silent operation and better shock resistance.

Build, connectors and daily use

The drive draws 3.5W active, 30 mW in low-power PS3 and 5 mW in sleep PS4, keeping thermals modest inside thin chassis. It operates from 0°C to 70°C and survives storage from -55°C to 85°C. A Western Digital-designed controller and firmware handle wear levelling and error correction. The SSD Dashboard utility monitors health and available spare blocks over the 1.7M-hour MTTF rating.

The spec that decides fit

Sequential read reaches 2400 MBps and write reaches 950 MBps, while 4KB randoms hit 170000 read and 135000 write IOPS. Endurance is rated at 150TB written. If your workload stays within these throughput and endurance bounds, the drive will serve well as a primary OS and application volume.

Questions about this item

What speeds does the PCI-Express 3.0 x4 interface cap at for this drive?

The drive reaches up to 2400 MBps sequential read and 950 MBps sequential write over the PCIe 3.0 x4 link.

What slot and physical size does the M.2 2280 form factor require?

It needs an M.2 key-M slot that accepts a 22 mm wide, 80 mm long single-sided module.

How do you install the SSD and which step is often missed?

Insert the drive at an angle into the M.2 slot, press flat and secure with the motherboard screw; many forget the screw and leave the drive unsecured.
