thank you very much for your time answering my questions !! ^_^
so now I understand SATA has advantage over IDE HDDs. but how about SCSI hard drives ?
SCSI HDDs have 10k RPM. does that make a whole lot of difference compare with SATA's 7200 RPM ? (33% faster ? or it has some other way to do the math).
if I am going to get a SCSI HDD, all I have to do is go get a "SCSI adapter". right ? btw, I have a P4P800-VM motherboard.
thank you

Well to have a SCSI HDD you have to have a SCSI controller and your HDD Data Transfer rate would also depend on SCSI controller capabilties.Secondly, SATA has many variants like SATA 1,SATA 2 and now SATA 3 is also out ....I guess.And SATA drives have much higher data transfer rate than SCSI.

SCSI HDD differ from IDE/SATA drives because they are dual-headed. This means they have the ability to read/write at the same time.
One of the items you need to look at is price difference. A 500G SATA is about $175. A $500 SCSI is around $750.
Granted SCSI is almost always server grade, but depending on what you are doing you will find that SATA and especially SATA 2 is more than enough performance for you.

I have tried installing both SATA and SCSI on my desktop and run some benchmark, the performance is roughly the same,
60-70 Mbps. (i dont know, probably my setting is not that optimal)
but with the price difference, it's more worthwhile getting SATA drives rather than SCSI drives.
Some recent studies even reveals that SATA drives are quite reliable to be deployed in enterprise level. imagine: 1 SCSI you can get 4 SATA, you can have raid 5 configuration.

Yes SCSI is designed for servers. They are much faster, though the reliablity to SATA has been questioned.
You'll need a SCSI controller to get it to work. The price of the hardware is not cheap. I don't really recommend it. For the cost, you can buy SATA drives and do your own RAID system and that should work fine.

SCSI is better and more expansive in terms of performance and requirement; but more expensive as well.
