At any rate, my point is this: I attached this drive (unformatted so I didn't benchmark anything) to my Father's IWill XP333-R system (which uses ATA/133 standard IDE connectors and features 2 ATA/133 RAID connectors) powered up the system and sure enough, the RAID Administrator and RAID BIOS say "ATA 133Mbytes/Sec" I shut down the PC, connected to the regular IDE connectors (non-RAID, ATA/133 ALi connectors, and sure enough) BIOS says, "ATA133" as well.
EDIT: You're not going to see ATA/133 using an ATA/100 "limited" controller, you have to use an ATA/133 controller. Also, if you're wondering, I used the IWill-provided "ATA/133" IDE cables. Although, from visual inspection they look just the same as ATA/66,ATA/100 cables, but just to be sure... LOL

I hope you realize that for the most part, ATA133 is a marketing gimmick. As well as ATA100. The theoretical transfer rates will never be reached. Heck, ATA33 is enough speed for the drives out on the market today. However, the faster "rates" indicated are usually accomplished through the faster rotational speeds, and better read/write speeds accomplished through faster mechanical parts in the drive. If you are going to go out and buy an ATA133, just realize that it really does not offer much more performance than an ATA100, let alone an ATA66 drive. It just all depends on what's on the inside of the drive. Those of you who are dropping the $ for an ATA100 or 133 card really shouldn't have to. If the drive specifies ATA100 or 133, it's going to read/write just as fast on an ATA66 controller.
