Intro
A Solid State Drive (SSD) is a hard drive that uses flash memory chips instead of magnetic disks.
Interfaces
Form Factors 1
2.5” SATA
Similar shape as the traditional HDD and connects to the same SATA cables.
mSATA
A miniature version of the SATA SSD designed for smaller form factor systems.
M.2
A small stick-shaped module that fits into an M.2 slot on the motherboard, avaiable as both NVMe (fast) and SATA (slow)
Quote
The M.2 SSD form factor emerged as storage for ultrathin computing devices; it is generally considered to be an eventual replacement for mSATA. An mSATA device supports any iteration of SATA but is not compatible with the M.2 connector. Conversely, an M.2 SSD supports SATA, USB 3.0 and PCIe 3.0
