Serial ATA is basically a
replacement for IDE which we have been using now for about 20 years. IDE
and EIDE were developed for desktop machines mostly, to allow them to
have high data capacity and data rates to the internal storage systems.
They did a superb job, lets face it with Apple & co coming round to the
idea from SCSI because of the fantastic value for money. IDE has used
ATA (Advanced Technology Architecture) in it's parallel form (PATA) and
the SATA systems are using the serial form.
SCSI disks will be
seen as too expensive for smaller servers with the advent of
Serial ATA (SATA) brings
easier installations because the cables are smaller and there is no
longer any requirement for Master/Slave configuration.
As well as this the data
rates are faster and the communication the disk makes with the interface
has been improved. Data rates for SATA are 300 and 600 MB/sec at both
the disk and interface.
connector - significantly smaller.
About Serial ATA
Industry leaders including Intel, Seagate, Maxtor, Dell, APT
Technologies designed Serial ATA. This group is known as the Serial ATA
working group and includes over 80 companies. This innovative interface
is designed to overcome the limitations of Parallel ATA and replace it
which it is doing as we speak.
Serial ATA offers consumers
a new level of interface scalable performance, flexibility, and cost
efficiency. Industry leaders designed Serial ATA with customer
convenience in mind by ensuring 100% software compatibility, flexible
thin cables, hot plug connectors, and improved data reliability and
With a maximum external
(burst) data transfer speed of 300 MB per second, Serial ATA improves
hard drive performance to keep pace with increasing data intensive
environments such as audio/video, consumer electronics and entry-level
servers. The new drives appearing Q4 2005 SATA-II drives allow transfer
speeds of 600 MB per second.
So is there a reason not to
make the move over to SATA. If you don't care about speed and want a
cheap option, IDE will be cheaper for a time.
SCSI is no longer
adequately outrunning SATA to be worthwhile so.....
....No - Get one!
