  • Form Factor2.5"
  • Capacity2TB
  • InterfaceSATA III
  • CacheNo DRAM (SLC)
  • Faster boot and application response with 520 MB/s sequential read

  • Extended laptop battery life from low power consumption
  • Works in older systems with SATA II backward compatibility

Capacity and interface

This Centon S1-S3A-2T is a 2TB internal solid-state drive in the 2.5 inch form factor with a SATA III interface. It is designed to replace a mechanical hard drive in laptops or desktops and deliver faster boot and application load times.

Suitable uses and limits

The drive suits anyone upgrading an older SATA-based system who wants lower power draw and silent operation without moving parts. It is less appropriate for platforms that only provide M.2 PCIe slots or for workloads needing sustained write throughput beyond the SLC cache.

Sequential speed rating

Sequential read reaches 520 MB/s and sequential write reaches 490 MB/s over the SATA III link, so those figures determine whether the drive meets the performance target for a given upgrade.

Questions about this item

Should I pick the 2TB SATA III version or a smaller capacity?

The 2TB model gives you the full 520 MB/s read and 490 MB/s write speeds in a 2.5 form factor; smaller capacities may have lower write performance.

What do the 520 MB/s read and 490 MB/s write figures mean once the drive is installed in my laptop?

Those are sequential speeds measured on a SATA III link; real-world boot and app launches will feel much faster than a hard drive but will not exceed those numbers.

The drive uses SATA III — what does that cap in practice?

SATA III limits the drive to its rated 520 MB/s read and 490 MB/s write; it also works in older SATA II slots at reduced throughput.
