Is the only difference between SATA and UltraATA/133/100 that SATA has transfer rates up to 150 MB/sec. and thiner chords; and that UltraATA has transfer rates of 100 or 133 MB/sec. To me 17 MB/sec. isnt that big a deal. Whats the real world differnce in speed, ive heard that theyre pretty much the same?

"ive heard that they're pretty much the same" Yeah a 7200rpm drive can get up to only about 70MB/sec, so in fact 100 is the same as 133 since in neither case does the full speed get used. Cached data does go at the full 100 or 133, but they both seems instantaneous.

They are planning to come out with SATA 300 very soon, I would wait a little while before purchasing in SATA drives I use 2 160gb IDE HDD at 133, 8mb buffer, 7200rpm and everything runs very fast I think once SATA 300 comes out then you will see a difference http://www.overclockersclub.com/?read=8255814 ________________________ MSI KT8 NEO Athlon 64 3200+ @ 2.0ghz 1.0 GB DDR PC3200 2X 160 GB HDD Hightech Excalibur Radeon 9800 Pro Iceq 128mb ( Core 425 MHz and Memory 380 MHz )

"I use 2 160gb IDE HDD at 133" Zero I hope that's Raid0. That is the fastest. The only thing that matters for now is the spinning disk. Raid0 for 7200rpm should be called 7200rpmddr, or 14400. 10k and 15k cost too much.

i have 1 raptor right now and it's pretty damn fast, next month i will get 1 more and run raid right now: norton anti virus scan 5-6 min defrag 5-6 min install ME 11 min install xp 21 min encode 4.3 gig mpeg-2 file into dvd format 12.5 min use drive image 7 back up/recovery: 7 min to reformat 26 of my 36 gigs 3 min to get into the recovery environment 17 min to restore hard drive with another raptor, i can expect my times to be nearly cut in half Abit NF7-s 2500+ @ 3200+ 512 Corsair XMS PC3200 128 meg Radeon 9800 Pro 36 GIG WD Raptor SATA 3+ Mbps cable connection

No don't run them in raid, thought if I run them in raid wouldn't I loose 160gb I use my main for XP and all my programs and put all my junk on the other drive Never done Raid before so wouldn't be 100% sure how to set it up properly without loosing data on my main drive Could give it a go though and see what the speed increase is How do I do it johnoh Thanks ________________________ MSI KT8 NEO FIS2R Athlon 64 3200+ @ 2.0ghz 1.0 GB DDR PC3200 2X 160 GB HDD Hightech Excalibur Radeon 9800 Pro Iceq 128mb ( Core 425 MHz and Memory 380 MHz )

Explains the Pros and Cons in both Raid0/1. http://www.madshrimps.be/?action=getarticle&articID=69 I only use Raid0 for video and audio editing.
