256 GB SATA M.2 2280 SSD

The Transcend 830S is a 256 GB internal solid-state drive built for the M.2 2280 slot and the SATA 600 interface. It targets personal, gaming and business systems that need a straightforward storage upgrade. The drive includes a DRAM cache and a Transcend controller.

Sustained write behaviour

Sequential write speed reaches 400 MB/s while the drive can read at up to 560 MB/s. Because the interface is SATA rather than PCIe, throughput stays consistent within the 600 MB/s bus limit during long transfers. The DRAM cache helps maintain performance when the workload extends beyond a quick burst.

Upgrade path from hard drives

This SSD replaces a 2.5-inch SATA hard drive or an older low-capacity SATA M.2 module in laptops and desktops. The jump is worth it when the system supports M.2 2280 and the user wants faster boot times, quicker application loads and silent operation without changing the storage protocol.

  • 256 MB DRAM cache improves random access responsiveness

Questions about this item

Does the 560 MB/s SATA 600 interface keep the Transcend 830S cool and quiet during all-day workloads?

With no moving parts and a low-profile M.2 2280 design, the drive runs silently and produces minimal heat under sustained SATA 600 throughput.

What must my motherboard provide for the TS256GMTS830S to be recognised and bootable?

A standard M.2 2280 slot wired to the chipset SATA 600 controller and UEFI firmware that supports SATA M.2 boot devices.

Will the 256 GB Transcend 830S work alongside an older 2.5-inch SATA SSD on the same controller?

Yes, each SATA device negotiates independently at up to 600 MB/s, so the 830S and a legacy drive share the bus without conflict.
