KR7A Raid & KR7A 133 RAID differences??

[Dexion]

I'm looking to replace my current motherboard with either the KR7A RAID or the KR7A 133 Raid. What I'm struggling to understand is the difference between the 2. I know for a fact that it is 2 seperate models from the Abit mobo lineup. Looking at the specifications are a bit skimpy and I can barely see any difference at all. Is this new KR7A 133 raid a marketing gimmick?

KR7A RAID Specifications
Notice the skimpier specs here. Note HPT372 controller at UDMA 100.


<< Four channels of Bus Master IDE Ports supporting up to 8 Ultra DMA 33/66/100/133( RAID 0 /1/0+1). >>




KR7A 133 RAID Specifications
Pretty much the same specs with little or no difference. The HPT372 Controller is now with UDMA 133.


<< Two Channels of Bus Master IDE Ports supporting up to four Ultra DMA 33/66/100/133 >>




<< Two Channels of Bus Master IDE Ports supporting up to four Ultra DMA 33/66//100/133 (RAID 0/1/10) >>



Enlighten me as to why the 133 version costs on average $20-$30 more?

nobody wants to comment? Is my question that stupid?

Here appears to be the difference. The boards use different Southbridges- KR7A Raid uses 8233 while the KR7A-Raid133 uses the 8233A. The "A" is probably an improved version with better potential for ATA133.

I also believe the KR7A-Raid133 can use ATA133 on all IDE channels while the non133 version only has ATA133 capability on the HPT controller (IDE 3 & 4).
