Differences between Abit KR7A-Raid, KR7A-133, KR7A-133R?

[PyroChang]

What the hell are the differences between these three mobos? All three of them use the same KT266a chipset?

Thnx

the KR7A Raid vs KR7A 133/KR7A133-Raid is a different southbridge chip that now incorporates ATA133 on IDE1&2 for the KR7A133 (which has a nonraid and raid version) ... the KR7A the southbridge chip only has ata100( the HPT controller on the raid version allows ATA133 on IDE3 &4..or of course raid)

KR7A....has only ATA100 support on IDE 1 and 2
RAID version allows ATA133 on IDE 3 and 4

KR7A-133 allows for ATA133 support on IDE 1 and 2(no ide 3 and 4 ports need HPT372 controller)
RAID version allows for ATA133 on IDE3 and 4 ..as well as RAID

oops..it was the southbridge hip...northbridge is the KT266A chip

Thanx nealh

The ATA 133 is really of no gain over ATA100

Wasn't the same thing said about AT100? & ATA66?

Yep. Current Hard Drive technology is limited that we don't need all this bandwidth unless you're using more than one device and of course, ATR shouldn't even be considered foir that because it's not a multi-tasking interface. ATA/66 is faster than ATA/33 on the latest drives

I agree you will see no difference with ata100 and ata133...I have a maxtor dx740 on ide 3 and Maxtor ata100 on ide 4 and there is no noticable performance difference....both 7200 rpm drives
