[dba-Tech] Software Firewalls

Hi Mark

The major advantage is that SATA is two-way while ATA is one-way,
either read or write. That's why ATA is no-no for heavy loaded servers
while SATA is useful (low price) though still not as fast as SCSI.

SATA does give a "theoretical" boost in two ways.  First is the
current
SATA/150 spec vs. the P-ATA/133 spec.  Second is the dedicated channel
vs. a
possible conflict with a second IDE device in the typical master/slave
setup.

But, having noticed a considerable improvement in performance when I
moved
to a drive with a 8MB cache when they first came out, I can't wait to
see
the performance gains in both my new Raptor (10k rpm) and my new
Maxtor
(16MB cache).

>From what I've read and tests that I've seen, SATA in itself doesn't
really
give a performance improvement. The improvement in SATA come from the
10,000
RPM drives used currently only on the WD Raptors (37Gb and 74 Gb)
AFAIK.
SATA 2 may be a different story, but I haven't seen any SATA2 drives on
the
market or SATA2 tests yet.
