Side-by-Side Comparison SSD

mSATA vs. PCIe AIC

Comparing 2 standards across 7 specifications. 7 key differences identified.

Comparing:
mSATA
PCIe AIC

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 M.2 has now largely superseded it.

PCIe Add-in Card (AIC) SSDs, commonly called HHHL (Half-Height, Half-Length), plug directly into a PCIe expansion slot like a graphics card rather than using M.2 or U.2 connectors -- trading compactness for the far greater power delivery and cooling surface area a full expansion card provides.
