Centon 1TB 2.5" SATA internal SSD

The Centon Electronics S1S3A1T is a 1TB internal solid-state drive built for the 2.5-inch form factor. It connects through the SATA interface to serve as primary or secondary storage in compatible laptops and desktops.

DRAM-less design with SLC cache

This drive uses a DRAM-less controller backed by an SLC caching scheme, making it suitable for everyday computing and older systems that only accept SATA drives. Buyers who want sustained write speeds for heavy workloads or a drive with a dedicated DRAM cache should look elsewhere.

SATA III interface

The single specification that determines fit is the SATA III connection; the drive will only work in systems that provide a standard 2.5-inch SATA bay or an appropriate adapter.

Questions about this item

How long will the SLC cache on this Centon S1S3A1T last before it needs replacement?

The drive uses an SLC cache without DRAM, so the cache itself is part of the NAND flash and does not require separate replacement during the drive's normal lifespan.

What limits sustained write speeds on this 1TB SATA SSD once the SLC cache fills?

After the SLC cache is exhausted, write performance drops to the native TLC NAND speed, which becomes the bottleneck during large continuous transfers.

How much heat and power does this 2.5-inch SATA drive produce when running all day?

As a SATA SSD with no moving parts, it generates minimal heat and draws low power, typically staying well within standard 2.5-inch drive thermal limits during continuous operation.
