Will a SATA-150 Drive work with a UDMA 33-66-133 Mobo?

I think I am missing something in how to check compatibility on this.

The Mobo has SATA connections, but this is my first build so I figure I'm bound to mess something up.

Post what motherboard it is and the rest of your specs.

If a motherboard has SATA ports, I'm sure it would support SATA drives. Otherwise that would be pretty stupid, no?
The UDMA ratings probably refer to the IDE port on the board.

MSI P965 Neo-F Intel Socket 775 ATX Motherboard

Yeah I think its for the IDE, but like I said this is my first build.

The UDMA rates are under the IDE, but I saw nothing on the details about SATA. Just an arrow on the diagram to the SATA ports.

I research pretty well, but I'm not exactly an IT.

Thanks for the help.

SATA 150 is technically UDMA 7. The BIOS is going to identify the UDMA mode of every SATA drive as UDMA 5. Do not worry, this is normal. There is nothing you can do about it.

As long as it works as a 300GB HDD and not a slug that is fine.

I guess I'm Intel Inside Idiot Outside.

Thanks.

Nah you're not, its better to ask a question than have it blow up later.
Plus now you can answer the question when the next person asks. :)

Hhmmm...I have a new Seagate Barracuda SATA 3.0 in one machine and a Hitachi SATA 3.0 in another and bios ID's them both as UDMA 6. Now, on both these builds I did NOT attempt to install any drivers beofre installing Windows and everything seemed to work OK. BTW...the Seagate is VERY quiet...no weird clicking noises.

However, they both benchmark as a drive index 76 MB/s and I have an older, ATA drive that benches at 67 MB/s in Sisoft.

So are my SATA's operating correctly?

SATA 3.0 means 3.0 Gbps. Which translated means 300MB/s (SATA has some overhead).

Any HDD you find will not exceed 80-90MB/s. UDMA5 is 100MB/s. 6 and 7 are who knows what (i'm too lazy to look beyond a quick google search).

If you don't have any problems, your HDD's seem fine.

UDMA 6 is 133MB/s, and UDMA 7 is 150MB/s. UDMA 8 (not sure if this is an official standard or not) would be 300MB/s.

Ahh excellent, thanks prophecy!
Good to know.. All the charts I found topped out at UDMA 5... I guess they haven't been updated.

Even newer BIOS'es will report SATA drives as running in UDMA 5 or 6. It's just the way it works. The charts probably have been updated.
