Will I see a difference between ATA100 and ATA66? Is ATA100 worth the extra cost?

I have an IGM 75GXP 7200rpm hard drive and I want to get either a Promise Ultra66 or Ultra100 controller card for it. There is a compatibility problem with the HPT controller on my BE6-2 and I can only run it in UDMA 2 mode or else it will lock up. So, will I see a difference with my hard drive and is the Ultra100 card worth $26 more? Please share any experiences or suggestions that you may have. TIA
 
If your only goal is to run that 75gxp as fast as possible then get the ata/66. That ibm can make use of its bandwidth. But ata/100 is overkill for all ide drives currently out and expected in the near future. We'll need ata/100 eventually but it's gonna be a long while.
 
Ultra ATA\100 drives at 7200 rpm drives are currently available. One online site that sells them is:
http://www.mpipc.com/

I know this is only one site, but if they sell them then others are most likely selling them as well.

I wouldn't bother

ATA66 is not as usefull as people hype it up to be in the first place, much less ATA100
 
Probably not, get the ATA66 promise controller so you can run it in mode 4, and get what you paid for.
 
current hard drives (ide) have just started to max out ata/33 so the extra bandwidth of ata/66 can be usefull....

currently no hard drive will max ata/66, so it is up to you whether you want a ata-100 controller card..
depending on when you plan to upgrade your motherboard next , eventually they will come with ata/100 controllers biult in anyway 🙂
 
Not sure if ATA-100 is also known as the "Serial ATA" spec, but if so, the reason for the new interface (when ATA-66 seems to offer plenty of headroom now) is the trend towards serialized bus models within computers. The advantage is lower pin count and less susceptibility to interference. Also, the 2-4 pin cables are a lot easier to route and organize than the ugly ribbon cables we have now. 🙂
