Axiom C550n 500 GB 2.5" SATA SSD

The Axiom C550n is a 500 GB internal solid-state drive built for desktop and embedded systems that need reliable SATA storage. It uses a Silicon Motion SM2258 controller with 3D TLC NAND to deliver consistent performance in a standard 2.5-inch form factor.

Capacity and headroom

At 500 GB the drive holds an operating system, core applications and a working set of files for typical office or light industrial workloads. Heavy media libraries or large game collections will exceed the available space and require additional storage.

SATA 6 Gb/s interface

The drive connects through a native SATA 6 Gb/s interface, so it fits any system with a standard SATA data and power port. Compatibility depends entirely on the presence of that interface.

Questions about this item

Will the C550n 500 GB SATA SSD fit in the same 2.5-inch bay as my older mechanical drive?

Yes, the drive uses the standard 2.5-inch form factor with a SATA connector, so it installs directly into any notebook or desktop bay that currently holds a 2.5-inch hard drive.

How can I verify the C550n is operating correctly once installed?

The built-in temperature sensor and S.M.A.R.T. attributes report drive health and temperature to the OS or monitoring software, confirming the SSD is functioning as intended.

Does the C550n package include a mounting bracket or adapter for a 3.5-inch desktop bay?

The drive ships as a bare 2.5-inch unit; a 2.5-to-3.5-inch bracket or adapter must be purchased separately if your desktop chassis only accepts 3.5-inch drives.
