SCSI HDD Transfer Rates Much Less Than IDE (?!?!)

[natewildes]

I've been using a 7200RPM 200GB IDE Maxtor for the last year+, and it works great. I managed to scavenge two SCSI Cheetah's (one 4.5gb and one 9.1gb, both running at 10Krpm) and a PCI SCSI controller card.
Here's what HDTune came up with for each drive:

As you can see, access time is much better on the Cheetah, but the transfer rates are AWFUL in comparison. Any thoughts as to what's causing this? Could the PCI card be limiting it?

Probably the card, The cheetahs are OLD too.

but old enough to give me under 20mb/sec transfer rates? good grief :(

If it were the card, the transfer rate would be a lot flatter. But yes, the drives are that old to have a transfer rate like that, even though they're 10K.
