| Short for SerialATA, SATA 1.0 was first released in August 2001
and is a replacement for the Parallel ATA interface used in IBM
compatible computers. SerialATA is capable of delivering 1.5Gbps
(150MBps) of performance to each drive
within a disk array, offers backwards compatibility for existing
ATA and ATAPI devices, and offers a thin, small cable solution as
seen in the picture to the left. This cable helps make a much easier
cable routing and offers better airflow in the computer when
compared to the earlier ribbon cables used with ATA drives. |

In addition to being an internal solution SATA also supports
external drives through External SATA more commonly known
as eSATA. eSATA offers many more advantages when compared
to to other solutions, for example it is
hot-swappable, supports faster
transfer speeds and no bottleneck issues when compared with
other popular external solutions such as
USB and Firewire, and
supports disk drive technologies such as
S.M.A.R.T..
Unfortunately however eSATA does have some disadvantages such
as not distributing power through the cable like USB, which
means drives will require an external power source and it only
supports a maximum cable lengths of up to 2
m. Because of these disadvantages
don't plan on eSATA becoming the only external solution for
computers.
