Often abbreviated
SATA
or
S-ATA
, an evolution of the
Parallel ATA
physical storage
interface
. Serial ATA is a
serial link -- a single cable with a minimum of four wires creates a point-to-point connection between devices. Transfer rates for Serial ATA begin at 150
MBps
. One of the main design advantages of Serial ATA is that the thinner serial cables facilitate more efficient airflow inside a
form factor
and also allow for smaller
chassis
designs. In contrast,
IDE
cables used in parallel ATA systems are bulkier than Serial ATA cables and can only extend to 40cm long, while Serial ATA cables can extend up to one meter.
