WESTERN DIGITAL Blue SA510 250GB 2.5 SATA SATA 3 Solid State Drive (SSD)

The Western Digital Blue SA510 250GB 2.5-inch SATA III SSD (model WDS250G3B0A) is a reliable internal solid-state drive designed to breathe new life into aging laptops and desktops. Built on Western Digital 3D NAND flash technology, it delivers consistent read and write performance suited to everyday productivity, creative workflows, and general computing tasks. In terms of sequential performance, the SA510 250GB achieves up to 555 MB/s read and up to 440 MB/s write speeds over the SATA III 6 Gb/s interface. Random performance reaches up to 80,000 IOPS read and up to 78,000 IOPS write, enabling snappy application launches and responsive multitasking. The drive is rated for 100 TBW (terabytes written) of endurance, with a mean time to failure (MTTF) of up to 1.75 million hours. The 2.5-inch, 7mm z-height form factor fits a wide range of laptops and desktop bays, making it a practical upgrade path for systems that use standard SATA connectors. Owners can use the free downloadable Acronis True Image for Western Digital software to migrate existing data, and the Western Digital Dashboard utility to monitor drive health, temperature, and available capacity over time. Power consumption is modest: average active power draws approximately 50 mW, with a max read operating power of 1,800 mW and max write operating power of 2,000 mW. Idle slumber and DevSleep modes draw only 36 mW and 12 mW respectively, helping preserve battery life in portable systems.
