SATA
SATA is the Acronym for Serial Advanced Technology Attachment
A storage interface standard introduced in 2003 to replace the older parallel ATA cables. It connects SSDs and hard drives to the motherboard using a thin, 7-pin data cable and a separate power cable. Common versions:
- SATA I → 1.5 Gbit/s
- SATA II → 3 Gbit/s
- SATA III → 6 Gbit/s (still the most common today)
SATA is the classic way most consumer SSDs and HDDs have been connected for the last 20 years. It’s reliable and universal, but its maximum speed of ~550–600 MB/s is now a bottleneck for modern high-performance SSDs.
