My SATA drive shows up as UDMA5

I bought a maxtor 250gb 7200RPM 8mb cache SATA drive and ghosted my winxp image to it flawlessly from an older 40gb HD. The drive is connected to my onboard SATA connection on my Asus P4P800 deluxe mobo. My issue is that the drive shows up as being an UDMA5 drive. Now, if i remember correctly, isnt that like ata/100 speed? I have a couple of other drives (Non SATA) in my system that is a mix of ata/100 and ata/133 and they show up as such. So why is my SATA which is supposed to be ata/150 not showing up as so? Thanks.
 
UDMA ratings are irrelevant in SATA. Remember UDMA6 is a fake rating that Maxtor (and someone else?) made up. UDMA5 is the hightest official rating in the industry.

Many SATA controllers show a UDMA rating on their controllers/drives for cosmetic purposes only.

Besides, UDMA5 will only limit you if you're running RAID0/5 over several drives.
