1TB NVMe M.2 2280 for consumers

The Western Digital Blue SN550 WDS100T2B0C is a 1TB internal solid state drive built for consumer PCs. It uses a single-sided M.2 2280 form factor with 3D NAND memory and a PCI-Express 3.0 x4 interface. The drive is designed to boost system responsiveness for everyday workloads. Its Western Digital controller and firmware are tuned for balanced performance and low power draw.

PCI-Express 3.0 x4 interface limits

This SSD connects through a PCI-Express 3.0 x4 link, which caps its maximum theoretical bandwidth. Sequential reads reach up to 2400 MBps and writes up to 1950 MBps within that ceiling. Random performance delivers up to 345000 IOPS for reads and 385000 IOPS for writes. The drive operates between 0°C and 70°C and idles at 30 mW in low-power state.

600TB endurance rating

The drive carries a terabytes written rating of 600TB, which is the single figure that determines whether it suits your write workload. A mean time to failure of 1.7M hours supports long-term reliability. Active power consumption peaks at 3.5W, while sleep state drops to 5 mW. These numbers define the practical service life for consumer use.

Questions sur cet article

Which capacity of the Blue SN550 NVMe should I pick for a typical desktop build?

The 1 TB model gives you 600 TBW endurance and 1.7 M hours MTTF, enough headroom for heavy daily workloads without over-provisioning.

What does the 2 400 MB/s sequential read figure mean once the drive is installed in my PC?

Large files such as game assets or video projects will load at up to 2 400 MB/s, cutting wait times compared with SATA SSDs while staying within the PCIe 3.0 x4 link.

Does the PCIe 3.0 x4 interface cap real-world throughput?

The four-lane Gen 3 connection limits peak transfer to the rated 2 400 MB/s read and 1 950 MB/s write, so you will not see higher numbers even on a newer motherboard.
