SSD
2.5-Inch SATA vs. PCIe AIC
Comparing 2 standards across 6 specifications. 6 key differences identified.
Comparing:
2.5-Inch SATA
PCIe AIC
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.
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.
