WD Green SATA M.2 2280 Internal SSD 120GB (WDS120G2G0B) — 545MB/s Read | 80MB/s Write | SATA | M.2 2280 | SLC Cache | 1M Hrs MTTF | 1-Year Seller Warranty by AdvanceKart

The WD Green SATA M.2 2280 SSD is built for laptop and desktop PC owners with an M.2 2280 SATA slot who want to upgrade from a slow hard disk drive (HDD) or replace an existing M.2 SATA SSD — for faster Windows boot times, faster application launch, and improved everyday system responsiveness — at an accessible entry-level SSD price point.

The 545MB/s sequential read speed is significantly faster than any mechanical HDD (typically 80–160MB/s) — enabling faster Windows boot, near-instant application launching, and responsive file access across everyday computing tasks. SLC (single-level cell) caching temporarily stores incoming write data in fast SLC mode before flushing to the main NAND — providing faster write performance for short burst tasks such as file copies, downloads, and software installations during everyday use. No moving internal parts means the WD Green SSD is completely silent in operation, more resistant to physical shock and vibration than HDDs, and generates minimal heat. Ultra-low power consumption compared to HDDs extends laptop battery life for portable use. The M.2 2280 form factor (80mm length, 22mm width) is the universal standard slot found in the vast majority of modern laptops and desktop motherboards with M.2 slots — ensuring broad compatibility. The SATA interface is compatible with all M.2 SATA-capable motherboard slots. Free Sandisk Dashboard software provides drive health monitoring, temperature, firmware updates, and SMART attribute reporting on Windows. Acronis True Image for Sandisk (free download) enables full drive cloning from an old drive to the new WD Green SSD for seamless migration without reinstalling Windows.

Important: This drive uses the SATA protocol over M.2. Verify that your laptop or motherboard’s M.2 slot supports SATA (not exclusively NVMe) before purchase. Some M.2 slots support only NVMe (PCIe) and will not detect SATA M.2 drives.
