Transcend 830S 128 GB M.2 2280 SATA SSD

This internal solid-state drive uses 3D NAND and a Transcend controller to deliver up to 560 MBps sequential read and 380 MBps sequential write over a SATA III interface. It fits the M.2 2280 slot and measures 3.1" deep, .9" wide and .1" high.

Suits SATA-only laptops

The SATA protocol limits throughput to the 600 MBps ceiling, so workloads that demand PCIe bandwidth will not benefit. Builders who require higher capacities or faster sequential speeds should select a larger or PCIe-based model instead.

Drops into any M.2 2280 key-M

No PCIe lanes are consumed, leaving them free for a graphics card or additional storage. The 128 unknown_modifier cache and DRAM-less design keep power draw low, while the 560 MBps read ceiling matches the SATA III link speed.

Questions about this item

Does my motherboard need an M.2 slot that supports SATA to use this 830S 128 GB drive?

Yes, the drive uses the M.2 2280 form factor with a SATA connector, so the slot must provide SATA signalling.

Will this SATA 830S work in the same M.2 socket where I previously used a SATA M.2 drive?

Yes, any M.2 2280 socket wired for SATA will accept this drive; it shares the same physical and electrical interface.

How can I confirm the 830S is delivering its rated 560 MBps read and 380 MBps write after installation?

Run a sequential benchmark tool such as CrystalDiskMark and compare the results to the 560 MBps read and 380 MBps write specifications.
