Sata I and Sata III

What is the difference between SATA I and SATA III?

I supposed you mean SATA1 vs SATAII.

SATA II mainly double the data troughput but it still backward compatible with SATA1.
(1,5 Gbit/s vs 3 Gbit/s)

no sata 1 and sata 3, so can i use sata 1 devices with either sata2 or sata3?

SATA III is simply the next generation of the SATA interface --> with a data rate of 600 MB/s

It is backwards compatible with SATA I and SATA II ==> so as you've suggested, you can use a SATA I device with either SATA II or SATA III controllers; and you can use a SATA III device with any SATA controller.

Don't be misled by the higher interface speeds, however ==> remember that all modern hard drives ... whether 7200 rpm, 10,000 rpm, or even 15,000 rpm ... have sustained transfer rates well below the interface rates of any of the SATA controllers; so the higher SATA interface speeds make very little difference in actual performance.   The only time there's ANY real life difference is in transfers to/from the disk's buffer ... which is a very small percentage of actual disk I/O.
ok, the real question is that i have a sata 1 raid card but 2 sata 3 drives i run them through windows 2000 server and i get a blue screen do you know why this is happening?
Most SATA II and SATA III drives hae a speed-limiting jumper that limits the interface speed to 150MB/s (SATA I speeds).   This is often needed to work with SATA I controllers ==> even though the specification says they SHOULD be fully backwards compatible, the simple fact is they often are not without this jumper.

Assuming your drives have this jumper, try that and see if it resolves your issue.

where would i need to situate the jumper in order for this to work?
What's the make/model of your drives?
western digital 300GB, we have no jumpers on these drives
Your controller may require the drives be jumpered for spread spectrum clocking.   There are two different ways WD drives are jumpered for Spread Spectrum ==> you should look up your exact drive model on WD's web site to be sure you've jumpered it correctly [or post the model # and I'll look it up for you].
WD3200AAKS is the hdd number and the raid card is an adaptech 1210sa
Well ... first of all, that's not a SATA III drive;  it's a SATA II drive :-)

But I suspect you still need to enable Spread Spectrum clocking.   You either have to add a jumper or remove a jumper to do this => depending on what the default setting is for your drive.   See the jumper settings here to determine which you have to do:

ok, i have tried what i was told on the site and have put the jumpers in the right place but it still blues screens
