View Full Version : PIO Modes?
11-03-2000, 12:45 PM
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...
Thanks for the tip anywho..
