ATA hard drive question

[XModem]

I have an Athlon 1.4 on a Gigabyte GA-7DXR board. This board has 4 IDE
connectors.

IDE 1 and IDE 2 Supports PIO mode 3, 4 UDMA 33 /
ATA 66 / ATA100 IDE & ATAPI CD-ROM

IDE 3 and IDE 4 Compatible with Raid, Ultra ATA100,
Ultra ATA66, Ultra ATA33, EIDE

Will I notice an improvement installing my new WD 160 GB drive on IDE3 vs.
IDE1? Is there much of a difference between regular ATA and Ultra ATA?

TIA.

There is no regular ATA vs Ultra ATA, they merely worded it
differently and both support UDMA, ATA33/66/100. IDE1 and 2
also support PIO mode and ATAPI, so an optical drive for
example would need be on 1 or 2.

The difference appears to be that the 3rd & 4th are provided
by a discrete controller sitting on the PCI bus. That makes
any devices connected to these 3rd or 4th, slower. Leave
the drive connected to 1 or 2 if the performance matters.
It may easily not matter if only store, rather than work
with common files such as video or music playback which have
playback requirements of a data rate still lower than the
performance would be.

Just what I was looking for. Thanks a bunch.
