2TB SATA upgrade for tired PCs

This 2.5 inch internal SSD brings 2TB of 3D TLC storage to any laptop or desktop with a SATA III port. The 7.00mm height fits ultrabooks and standard drive bays alike. Sequential reads reach up to 560 MB/s in ATTO and up to 500 MB/s in CDM, while writes hit up to 530 MB/s and 450 MB/s respectively. It is built for everyday consumer workloads.

Silent operation with no moving parts

Solid-state design means zero noise and no mechanical vibration sensitivity beyond the rated 20G. Power draw stays low because there is no spindle motor, helping battery life in portable systems. The drive weighs 63.00g and measures 69.85mm by 100.00mm. MTBF is rated at 1500000 hours for long-term reliability.

SP Toolbox software monitors health

The free downloadable utility reports S.M.A.R.T. attributes so you can track drive condition over time. Firmware-level features include TRIM, garbage collection, ECC and bad-block management to sustain performance and data integrity. SLC cache technology accelerates burst writes while the DRAM cache buffer improves sustained throughput.
