Overview
The Western Digital Green 120GB M.2 2280 SATA SSD (model WDS120G2G0B) is designed for users who want a straightforward, energy-efficient storage upgrade for their everyday laptop or desktop computer. Fitting the widely supported M.2 2280 form factor, this drive connects via a SATA III 6 Gb/s interface and delivers sequential read speeds of up to 545 MB/s, making routine tasks such as web browsing, application loading, and casual gaming noticeably more responsive compared to a traditional spinning hard drive. The drive employs SLC (single-level cell) caching to accelerate write operations in burst workloads. With no moving parts, it offers greater resistance to physical shock — rated at 1,500 G at 0.5 msec half sine — which helps safeguard data if the device is accidentally knocked or moved. The drive operates within a temperature range of 0°C to 70°C and is rated for vibration resistance up to 5.0 gRMS across 10–2000 Hz during operation. Power efficiency is a clear strength of this drive. Average active power consumption is just 80 mW, with a slumber state drawing only 30 mW and DEVSLP mode reducing draw to as little as 10 mW. These figures make it a practical choice for notebook users looking to extend battery runtime. Western Digital backs this SSD with a mean time to failure (MTTF) rating of up to 1.0 million hours and a 3-year limited warranty. The free WD SSD Dashboard software lets users monitor drive health, firmware version, S.M.A.R.T. attributes, and available capacity.
