JimEckleberry, I'm not sure what you mean by "CitrixEngineer, since the data bus currently isn't even maxxing out the Ultra ATA/66 spec yet you don't have to worry about the 133 spec. The problem will be fixed before you need it."
I have seen benchmarks showing data burst rates in excess of the ATA/66 spec on existing ATA/100 boards (as one might expect).
Of course, for Sustained Transfer Rates, you are quite right - 40MB/s is about the best that the fastest that IDE can manage.
The 266a is proven to be slower for disk transfer than the 266 or even the old 133 Via chips. Even the Intel chipset beats it hands down. This chipset even slows down SCSI. Look at the benchmarks at
This is not to detract from the excellent performance in other areas of the 266a chipset, however - just to point out that it is not yet the top dog that it undoubtledly will become.
I would not touch a board with this chipset, beacuse, IMO, disk performance is absolutely key to a stable, fast system.
Quote "it is not clear whether new drivers will be enough, or whether it will need a redesign of the chipsets." (from The Register).
BrZ - you've got a Radeon 8500? >envy<
