Local store is selling DiamondMax PLus 15g UltraAta100s for $154CAN.
i was planning to purchase quantum fb lm but the prices here have went up.

anyhow, to the real question, is there a big performance difference between ata 66 and ata100?

Yeppers,

The ATA100 is potentially %50 faster than the ATA66. It follows that the ATA66 is twice as fast as ATA33.

ATA100 will support 100, 66 and 33 drives. I recommend the ATA100 controller.

I put a IBM deskstar 7200-15 ata100 on an A7V for a buddy, very fast drive, only cost 100$ I have a 5400 66 WD on the same board, no comparison...

It's the RPMs that make that drive faster.

In answer to your question, NO. You won't see much, if any, difference in speed between ATA-100 and ATA-66. Truth is, current technology doesn't even take full advantage of ATA-66.

Yep, RPM Vs. Burst Rate, you're going to see more of a difference on RPM! You won't see much of a difference on UDMA-66 Vs. UDMA-100.

Go for the fastest RPM drive you can afford, incase of IDE, that would be 7,200RPM, for SCSI that would be 15,000RPM. Best bang for the bucks, get an IDE 7,200rpm drive, SCSI drives are just too pricy!

I'm with OuT and NDC.

Not even then fastest IDE hard drive can sustain even 33MB/second. Get yourself a fast RPM hard drive.

Think of the ATA/100 bus as the road and the HDD as the car; putting a Yugo on a racetrack that is built for speed won't make the Yugo go any faster. http://sysopt.earthweb.com/forum/wink.gif

No where near 66mb/s, but only a bit over 33mb/s. The average doesn't say anything because only the first 8gb are benchmarked.

ATA100 won't be necessary for quite some time.

The Ultra ATA/33/66/100 drives never even nearly covers the avaiable bandwidth. But as the speed it goes at increases at proportion.
