Serial ATA

[Johnny Lingo]

If a mobo is compatible with an ATA 100 hard drive I can still use a serial
ATA 150 hard drive right? It is my understanding that it will just run at
the 100 and not get to 150. Is this correct???

Disregard, I have already answered my own question
Thanks!

As with the majority of Hardware, one generally finds it true in that a new version is backwards compatible.

Before you buy a SATA Hard Drive and plug it into your SATA100 controller, why bother spending the extra money for 150, if you're only getting 100 performance.

Truth is that you probably won't get 150 MB/s ever. Just a note, SATA
requires a totally different interface. Check and make sure your
motherboard supports SATA or you will have to buy a SATA PCI Card.
Also, SATA drives usually perform at DMA Mode 5 (ATA100) and offer a max
of DMA Mode 6 (ATA133) when used as a single drive. RAID is a different
story

If your mobo has a SATA controller it will run the SATA

drive at 150 and the ide drive at 100. The only
exception I know of is with certain Promise SATA
controllers that allow an SATA drive and a 133 drive to
be setup in a RAID configuration in which case it
defaults to the slower 133. If you have to use an add-in
controller for an SATA drive, keep in mind it will have
to share the pci bus with other devices so you may not
see much benefit. That said you can still use an add-in
card with an SATA drive as a way of future-proofing for
when you have a dedicated SATA controller.

ATA drives are parallel bus - SATA is Serial ATA

SATA drive on an ATA bus will not work.

Actually, it will, but it takes a special convertor like this one:

I see no point in crippling it like that though. All of these higher
speeds can only be reached in RAID configuration, so I don't see why
everyone is so gung-ho on SATA over PATA. I'm waiting for SATA300 and a
nice 10K RPM Drive. Get two and I'll be happy
