sata150/sata300

ja det burte ikke være noget problem

Are the new SATA-II / SATA3.0 drives 100% compatible with all SATA150 controllers?
I understand the speed would be slower and NCQ wont work, but performance aside, do the drives always work?

Yes.  In the same way that you can use ATA/133 drives with ATA/100 or ATA/66 controllers, the newer and faster drives are backwards compatible.  They will, of course, operate only as fast as the controller will permit.

This should help:

Both the harddrives and motherboards are backwards-compatible.

A thing to note:  Alot of drive manufacturers are actually shipping SATAII drives with the firmware limiting them to 150Mbps.  Check with the manufacturer if you get a drive as it may require a firmware upgrade to take advantage of SATAII speeds.  They do this to maintian backward compatability as some 150 controllers wont work with drives that have the SATA II firmware for some reason. 

Read this bit on toms hardware....  Trying to find a link.

What dumpsterdivingdave says is true - I have an Hitachi 160GB that needed to be flashed with their utility to make it work as SATA II, and the Samsung drives I got recently have a jumper to force them into SATA I mode.

So..If I understand this correctly, SATAII drives are more compatible with SATA150 than they are with their own controllers!?

I ask because as a small systems builder, I would rather stock SATA300 drives, since the price is the same, but these will need to be compatible with older SATA system boards for warranty purposes.

This will not be a problem with Samsung drives, since they have a jumper for compatability.  I suspect as time goes on, this will become a non-issue, like ATA100 versus ATA133 drives.  The actual difference in performance will be minimal, since the drive buffers will empty out in less than a second, and then the maximum sustained transfer rate will be around 70MB/sec, which is much less than the 1.5Gbit/sec burst rate of SATA I.

I would stock the SATA II as when put in a raid combo equal the performance of the WD Raptor drives, and can sometimes out-perform them.  SATA 150 was the first step, (kinda a test phase to see if the industry would accept it well) and since it did, SATA II came right behind.  All new MOBO's support SATA II, so that's what I would stock.
