Performance difference between ATA 66 and ATA 100...

Some people say that there is not difference. Is this true?

It's true and it's not true.

It's true because no current drives can transfer data from the platters at 66MB/sec (the fastest are around 40MB/sec).

It's not true because ATA 100 drives can transfer data from the drive cache at 100MB/sec.

In actual use there is no significant difference between the two.

In fact, there isn't much difference between ATA 33 and ATA 66 but it's much larger than the difference between ATA 66 and ATA 100.

By the time faster ATA-100 harddrives come out with higher transfer rates then the current models we probably have ATA-133 round the corner ,nothing stays top in speed for long.

Agree, I don't think anybody can feel the difference between the two. I'm using both now and benchmarked both with the IBM scoring a little higher.

There is currently no difference between 66 and 100. There is a very small difference between 33 and 66.

NO IDE drive can currently peak the 66MB/s sustained transfer rate
however, they CAN peak the 66MB/s when transferring from HD cache

i would say the performance difference overall is less than 3%
not sth you should worry about

I used HD Tach on ATA100 hardrives on ATA100 & ATA66 controller.
MIN MAX & Average where the same, only the burst was greater 56mb/s compared to off the scale at 80mb/s.
