Serial ata drive only at udma 5?

[Spydc]

I have a dell dimension 4600 with a 120GB Seagate serial ata drive and all windows updates....Window's device manager reports the drive as running at udma 5 (ata100 speed) and the hdtach benchmark is showing burst rates of a drive that is set at ata100. I thought that serial ata drives were ata150.... I would think that at the very least the burst rate will be similar to a ata133 drive, but it is not Any suggestions?

Does that drive use a PATA-SATA converter chip? My Raptor does and gets bursts of ~95MB\s. It's no big deal, sustained transfers are what matters most.

i'm not familiar with the pata-sata converter chip so i'm not really sure to tell u the truth.

Same thing here, with a Maxtor and A7N8X dlx, Aida32 reports at Udma5, ata100. Aida says drive is capable of Udma6.
