Transcend SSD220S 480GB SATA III drive

The Transcend SSD220S is a 2.5 inch internal solid state drive with 480GB capacity. It connects through a standard SATA III interface and uses TLC flash memory managed by an SM2256KAB controller. This drive suits desktop or laptop owners replacing a mechanical hard disk for faster boot and application load times.

Silent low power operation with DevSleep

The SSD runs silently because it has no moving parts and draws minimal power in normal use. DevSleep support lets the drive enter an ultra low power state when idle, extending battery life on portable systems. Operating temperature ranges from 0°C to 70°C, so it handles typical workloads without thermal throttling.

Upgrade from a 2.5 inch hard disk

Replacing a 2.5 inch hard drive with this SSD removes mechanical latency and vibration sensitivity. Sequential reads reach 550 MBps and writes reach 450 MBps, while random 4KB performance hits 80,000 IOPS read and write. The jump is worth it when faster system responsiveness and silent operation matter more than maximum capacity.

Questions about this item

How do I install the 2.5" SATA SSD into my laptop or desktop, and what step is often missed?

Mount the drive in a 2.5" bay or caddy, connect the SATA data and power cables, then enable AHCI mode in BIOS before installing the operating system.

What maintenance will the 480GB TLC drive need over its lifetime?

The controller manages wear levelling and TRIM automatically; keep free space available and run occasional S.M.A.R.T. checks to monitor health.

What limit appears first during sustained heavy writes on this SATA III drive?

Sequential write speed is rated up to 450 MBps; the SLC cache will fill and speeds will drop to native TLC rates once that buffer is exhausted.
