What this drive is

The Western Digital Blue SN550 is a 1 TB NVMe solid-state drive in the M.2 2280 form factor. It connects over a PCIe 3.0 x4 interface and delivers sequential read speeds up to 2,400 MB/s. The single-sided design fits small-form-factor desktops and laptops. A WD-designed controller and 3D NAND provide consistent performance for everyday workloads.

Who it suits and who it does not

This drive suits builders who need a cost-effective NVMe upgrade for a system with an M.2 slot wired for PCIe 3.0 x4. It is not for buyers who require higher sequential throughput or sustained write performance for heavy content creation. It is also not for systems that lack an M.2 2280 slot or that only support the older AHCI protocol.

The deciding specification

The PCIe 3.0 x4 interface and 2,400 MB/s peak sequential read speed are the figures that determine whether this drive matches the slot and performance target of the build. If the platform provides a compatible M.2 2280 key and the workload benefits from NVMe speeds, the drive will operate as specified.

Questions sur cet article

How can I confirm the drive reaches its rated 2400 MB/s sequential read speed after installation?

Run a benchmark such as CrystalDiskMark on the M.2 NVMe drive; the sequential read result should approach 2400 MB/s on a PCIe Gen3 x4 slot.

What is included in the box and do I need a separate heatsink or mounting screw?

The package contains the single-sided M.2 2280 SSD only; a motherboard standoff screw is usually supplied with the board, and the drive operates within spec without an extra heatsink.

Which capacity should I choose between the 550 GB and 1 TB versions for a primary OS and apps drive?

The 1 TB model provides more space for the operating system, applications and active project files while delivering the same 2400 MB/s sequential read performance.
