Not necessarily.  SATA is faster than any parallel IDE interface.  It is
almost, but not quite, as fast as fast, wide SCSI (SCSI-3).  It's easier
to cable up than SCSI and the cables can be longer.

However, the drives currently are more expensive than IDE, but generally
less than equivalent SCSI drives.  IDE is SCSI, stripped-down to save
money.  ATA is essentially SCSI commands sent over IDE interfaces.  SATA
is a higher performance form of ATA.

Personally, except for server systems, I see very little benefit of SATA
over IDE.  And since you can only have two SATA drives per controller
(just like IDE), I don't think it's that great for servers, either.  For
most servers, you want something more beefy than a software RAID 1, more
like a hardware RAID 4, RAID 5, or RAID 10 and they all still require
SCSI.

I find it funny that the hard drive makers are parallelling the
MSDOS/Windows fiasco of a development cycle.  When Microsoft essentially
stole CP/M to create MSDOS, network code was already in the product (I
know...I was one of the authors).  Microsoft ripped it out, and now has
spent the last 15 years trying to put back in stable network code.  The
IDE/ATA/SATA makers are attempting to get back to the speeds and
flexibility that SCSI had 15 years ago and they abandoned.
