2.5-Inch SATA vs. mSATA
Comparing 2 standards across 5 specifications. 5 key differences identified.
The 2.5-inch SATA SSD shares its physical footprint (100mm x 70mm) with laptop hard drives, making it a drop-in upgrade. SATA III limits it to a real-world maximum around 550-600 MB/s regardless of how fast the drive's flash memory could otherwise go.
mSATA (Mini-SATA) packed a SATA interface into the same physical card size as Mini PCIe, standardized in 2011 -- but despite sharing its connector and outline with Mini PCIe, it's electrically incompatible, carrying SATA signal lines instead of PCIe lines. M.2 has now largely superseded it.
