Transcend MSA372M 32GB mSATA SATA III Internal SSD, MLC NAND with DDR3 Cache, for Industrial & Embedded PCs

Transcend MSA372M 32GB is an mSATA (SATA III 6Gb/s) SSD with MLC NAND and a DDR3 DRAM cache, built for industrial PCs, thin clients, POS terminals and older laptops that use the small mSATA card slot.

mSATA is the card-style SATA format that preceded M.2: a 50.8 x 29.85 mm board that plugs into a dedicated mini-PCIe-shaped socket but talks SATA. It is common in embedded boards, kiosks, network appliances and 2011–2015 notebooks. Transcend now lists the MSA372M under its embedded solutions, with MLC flash, a 2,500,000-hour MTBF and features aimed at long, stable service — Corner Bond for shock, anti-sulfur and Power Shield against sudden power loss.

At 32GB this is a boot or firmware drive for a lean OS (embedded Windows, Linux, thin-client images), not general-purpose storage. Transcend publishes performance and TBW only for the family's largest capacities, so no speed figure is given here for 32GB.

• Transcend MSA372M 32GB mSATA SSD (Transcend does not list accessories)

• Fits only an mSATA socket — check that your board or laptop manual says mSATA (not M.2 or mini-PCIe Wi-Fi).
• Standard temperature version (0–70 °C); for −40 to 85 °C environments the wide-temperature MSA372I is the matching part.
• Supports DevSleep for very low standby power in mobile and embedded devices.
• Power Shield helps protect data during sudden power loss — useful in kiosks and machines that get switched off at the wall.

• M.2 slots of any kind — mSATA and M.2 are different, incompatible connectors.
• Mini-PCIe slots meant for Wi-Fi or WWAN cards, even though they look identical.
• 2.5-inch SATA bays, unless you use an mSATA to 2.5" adapter.
• Desktop-class storage needs: 32GB is for a lean OS or firmware image only.
