Axiom SSD2558X500-AX 2.5" SATA internal SSD

Axiom C550n 500 GB SATA SSD

The Axiom C550n is a 2.5 inch internal solid state drive built for PCs, ultrabooks and embedded systems that need reliable SATA storage. It uses a Silicon Motion SM2258 controller with 3D TLC NAND to deliver consistent performance for mixed workloads. TRIM, wear levelling, static data refresh and LDPC ECC protect data integrity across the drive lifespan. S.M.A.R.T. monitoring and a built-in temperature sensor help track health in real time.

2.5 inch form factor with SATA III connector

The drive measures 3.94 by 2.76 by 0.28 inches and fits standard 2.5 inch drive bays using a native SATA connector. Active power draw is 2.10 watts and DevSleep support reduces consumption further during idle periods. No moving parts mean silent operation and resistance to shock or vibration. The SATA III interface works in both SATA and SAS environments without extra adapters. SLC caching boosts burst read and write speeds for everyday tasks.

Upgrade from mechanical hard drives

Replacing a traditional spinning disk with this 3D TLC SSD typically improves system startup, application loading and backup times. Sustained sequential reads reach 400 MB/s and writes hold at 400 MB/s, while maximum sequential reads hit 500 MB/s and writes 400 MB/s. The jump is worth it when faster boot and responsiveness matter more than raw capacity. Compatibility spans any operating system that supports the SATA protocol.
