Axiom

Axiom C550n Series 1TB SATA SSD

SKU CH-XZQZ-WPC5X

A SATA 6Gb/s SSD with Silicon Motion SM2258 controller and 3D TLC NAND for faster boot, load and backup times

  • 1TB capacity stores large files and applications
  • SATA 6Gb/s interface delivers fast data transfer speeds
  • 3D TLC NAND with SM2258 controller ensures reliable performance
  • TRIM, Wear Leveling and LDPC ECC protect data integrity
  • DevSleep support reduces power consumption for longer battery life

Axiom C550n Series 1TB SATA SSD

The Axiom C550n Series 1TB SSD is a 6 Gb/s SATA drive built with 3D TLC NAND and a Silicon Motion SM2258 controller. It targets cost-effective upgrades for PCs, Ultrabooks, tablets and embedded systems where low power draw and small form factors matter. TAA compliance makes it eligible for government procurement.

Suits SATA-only upgrades and embedded deployments

This drive fits buyers replacing a spinning hard disk in a SATA-equipped laptop, desktop or industrial appliance and who need DevSleep support for longer battery life or lower cooling costs. It is not for platforms that lack a SATA interface or that require a PCIe-attached drive.

550 MB/s sequential speed

The headline transfer rate of 550 MB/s determines whether the drive meets the throughput needs of a given workload. Systems that demand higher sequential bandwidth should evaluate faster interfaces.

Questions about this item

How do I install the 2.5-inch SATA SSD and what step is often missed?

Connect the SATA data and power cables, secure the drive in a 2.5-inch bay, then enable AHCI mode in the BIOS so the Silicon Motion SM2258 controller can use TRIM and NCQ properly.

What maintenance or replacement will the 3D TLC NAND need over time?

The drive handles wear levelling, static data refresh and LDPC ECC internally; no user maintenance is required, but the NAND will eventually reach its program/erase limit and the SSD must be replaced.

What limit appears first during sustained heavy writes on this SATA 6Gb/s SSD?

The SLC cache fills and write speed drops toward the native 3D TLC NAND rate while the SM2258 controller manages thermal throttling via the built-in temperature sensor.
