This 64GB mSATA SSD has very fast (sequential) read speeds with notably slower writes. The 64GB size I bought is convenient for replacing small system drives or other embedded purposes, but will be on the small side for most modern storage purposes. I used mine in a MSI Cubi mini-PC, where it has been running 24/7 for the past six months. Despite the low-end system (and presumably low-end controller), this Transcend clocked sequential read-speeds well above 450MB/s.
The mSATA format itself is obsoleted by the M.2 (and U.2) format; given the choice, go with the newer formats. M.2 will generally cost no more than mSATA, offer a greater range of sizes, and M.2 interfaces often accommodate non-SATA drives as well.
Here's how FreeBSD 11 saw the drive in my Cubi:
ada1: <TS64GMSA370 O1225G> ACS-2 ATA SATA 3.x device
ada1: 600.000MB/s transfers (SATA 3.x, UDMA6, PIO 1024bytes)
ada1: Command Queueing enabled
ada1: 61057MB (125045424 512 byte sectors)
I usually think of Transcend as a removable media manufacturer, but I suppose it's not a big leap from flash-based media to flash-based SSD products. I've been pleased with this unit's performance and would buy again.
