I would agree with many of your points save one. HW RAID (not including Promise IDE stuff because that's not a true HW controller in the same sense that a Compaq SMART Array Controller is) is always going to be faster. There is no way, for instance, SW RAID could compete with say a 6400 w/256MB Cache Module.
You really should look at http://spamaps.org/raidtests.php
This only applies to the promise IDE controller. You would have to make simular tests against a SCSI controller for comparison. SCSI disks are generally faster (and more reliable) all around than IDE, although IDE has made some strides lately.
Maybe you should have actually followed the link instead of blindly assuming what it contained.
Allow me to quote the page:
Hardware: Tyan S2466-N4M AMD760MPX Chipset Motherboard 2x AMD Athlon MP1900+ CPU 512MB Crucial ECC Registered PC2100 DDR RAM running at 266Mhz. Single Maxtor 80GB HDD using onboard PATA for OS. 3ware Escalade 8506-8 SATA RAID Card 4x WDC250GB 7200rpm SATA HDDs
I did follow the link but the fingers overroad what the brain was thinking. Yes it is a 3ware controller, not a promise controller but the rest remains the same. SCSI is generally better and faster then SATA. Why do you think SCSI drives have a 5 year warranty and most IDE have one? because they are of better quality. And yes anything get break on day one. And you can always buy SCSI drives that are faster then even the fastest SATA drives. -- Ken Schneider unix user since 1989 linux user since 1994 SuSE user since 1998 (5.2) * PLEASE only reply to the list *
