PIO Modes?

[gwilks98]

I was reading that a PIO mode 4 is capable of transfering data at 16.6 MB/s. I looked in my BIOS settings a lo and behold, I have a PIO of 4 for my hard drive. Here's where the question fits in:
I'm using an ATA100 hard drive on a CUSL2 mobo, so shouldn't I be getting a max transfer rate of 100 MB/s, and not 16.6?

ATA100 is the theoretical burst rate you'll get from the hard drive. A more consistent transfer rate is about 35 megs with the latest hard drives like IBM's 75GXP series of hard drives.

A couple of good CUSL2 sites with tips:

I should have read further....

ATA100 refers to direct memory access. PIO refers to transfer rates to the CPU itself...


Oh well.

Thanks for the tip anywho..
