ADATA Ultimate SU650 256GB SATA 3D NAND 2.5 SATA Internal Solid State Drive ( SSD )

The ADATA Ultimate SU650 256GB is a 2.5-inch internal solid state drive designed for users looking to replace a mechanical hard drive or breathe new life into an ageing laptop or desktop. Built on 3D NAND Flash technology, the SU650 stacks memory cells vertically to achieve greater storage density and improved endurance compared to planar 2D NAND designs. At the heart of the drive's performance is an intelligent SLC caching algorithm that temporarily treats a portion of the NAND as single-level cell memory, allowing burst read speeds of up to 520 MB/s and write speeds of up to 450 MB/s over the SATA 6 Gb/s (SATA III) interface. Day-to-day tasks such as OS boot, application launch, and large file transfers all benefit from this headroom over traditional hard drives. Data integrity is protected by integrated ECC (Error Correction Code) technology, which detects and corrects bit errors on the fly. The drive carries a mean time between failures (MTBF) rating of 2,000,000 hours and a total bytes written (TBW) endurance figure of 140 TB, giving a clear picture of long-term reliability. A 3-year limited warranty is included. With no moving parts, the SU650 withstands shock up to 1500G/0.5ms and operates reliably across a temperature range of 0°C to 70°C, while storage temperatures span -40°C to 85°C. The slim 7mm chassis fits standard ultrabook bays, and a 2.5mm spacer is bundled for 9.5mm drive bays, ensuring broad compatibility. Every purchase unlocks free downloads of ADATA SSD Toolbox — for monitoring drive health, wear level, and estimated lifespan — and Migration Utility, which simplifies cloning an entire existing drive, including the operating system, to the SU650.
