Axiom SSD2558X1TB-AX C550N 2.5 inch SATA internal SSD

1 TB SATA SSD for laptop upgrades

The Axiom SSD2558X1TB-AX is a 1 TB internal solid-state drive built for 2.5-inch bays. It targets users who want to replace a mechanical hard drive in a laptop or compact desktop with a faster, silent alternative. The SATA 6 Gb/s interface works with any system that accepts a standard 2.5-inch SATA drive.

7 mm z-height fits slim chassis

The drive measures .28 in tall by 3.94 in wide by 2.76 in deep, matching the 7 mm profile used in thin-and-light notebooks. A single SATA connector handles both data and power, so installation only requires sliding the drive into the bay and securing it with the existing screws. No extra cables or adapters are needed for daily operation.

SATA 6 Gb/s sets the speed ceiling

Sequential reads and writes are limited by the SATA 6 Gb/s protocol rather than by flash architecture. That ceiling determines whether the drive can saturate the bus in typical workloads such as OS boot, application launch and large-file transfer. Buyers should confirm their platform supports SATA III to get the rated throughput.
