Green SN350 NVMe 240GB

The Western Digital Green SN350 is a 240GB internal SSD built for everyday consumer workloads. It fits laptops and desktops with an M.2 2280 slot and connects through a PCI-Express 3.0 x4 NVMe interface.

Capacity and endurance

The drive provides 240GB of storage and is rated for 40TBW of total bytes written. Sequential reads reach up to 2400 MBps and writes up to 900 MBps, while random 4KB performance hits 160,000 read IOPS and 150,000 write IOPS, enough for OS boot, apps and light content work.

Power and thermals

Active power draw is 3.5W, dropping to 25 mW in PS3 low-power state and 5 mW in PS4 sleep. The controller operates from 0°C to 70°C and survives storage temperatures from -40°C to 85°C. With no moving parts it runs silently and resists shock up to 1500G.
