Western Digital Green SN3000 1 TB NVMe SSD

The Western Digital Green SN3000 is a 1 TB internal solid-state drive in the M.2 2280 form factor. It uses SanDisk QLC 3D NAND and connects through a PCI-Express 4.0 x4 interface with the NVMe protocol. The drive has no DRAM cache and relies on host memory buffer technology. It is intended for consumer notebooks and desktops that need extra capacity and faster boot times.

Thermals and power in normal use

The controller is rated for an operating temperature range of 0°C to 80°C. Because the design omits a DRAM cache, typical power draw stays low during everyday tasks such as web browsing and document editing. The single-sided M.2 2280 layout fits thin laptops without adding bulk. No active cooling is required for standard workloads.

Behaviour under sustained load

Sequential reads reach up to 5000 MBps and writes up to 4200 MBps until the SLC cache fills. The drive carries a 150 TBW endurance rating and a 1 million hour MTTF figure. Shock resistance is specified at 1500G at 0.5 ms half-sine. Extended heavy writes will throttle once the cache is exhausted, so the drive suits bursty workloads better than continuous video capture.
