SATA & SATA II

Angel.of.Death · 11-04-2006, 06:46 AM

Im building a new comp, and i have a question.

My new mobo is compatible with SATA II. If I use my old SATA hardrives with my new motherboard, will SATA II be enabled?

Yes, they are compatible with each other.

OK so SATA I / SATA II doesnt depend on the HDD itself, but the mobo its connected to...

Ok i see... Thanks for all your help

Well, the HDD has a part in it too but you can mix and match them with no harmful effects. You wont have 3Gbps peak transfer rates unless both components are capable of pushing that much data. Realistically, you aren't going to use the full 1.5Gbps even with Raptors.

So are you trying to say that SATA - II is a marketing scam?

Thanks for all your help

Also, what would you need to reach that peak?

Sort of. You can't touch the max transfer speed of the specification but there's a bit more to SATA II than just the transfer speed.

If you wanted to get 3Gbps off a single drive you'd need such a fast spindle speed the drive would have a very small capacity. You can do it with RAID arrays but that's across multiple drives and so you have even more bandwidth available.

I had the same question a few months ago...

SATA 3.0Gb/s backwards compatible

Thanks a lot for all your help guys...

I've come to the conclusion that I dont need to buy a new HDD... Ill just use my 2 120GB's in a RAID 0 config.

BTW, Whats the max bandwidth you can achieve with RAID 0 ?

**Cromewell** · 11-05-2006, 02:24 AM

It depends how many drives you put in it. Have a look at http://www.computerforum.com/70401-post3.html

Thanks.

Will 3.0Gbps be achievable with 2 or 3 drives in RAID 0? I plan to use 2 x 120GB's now and chuck another one in when I need it...
