Is there a noticable differance between ATA100 and ATA66?

[mikef208]

I have heard that the peak transfer rate is only 44MB/sec anyway, so would you notice the differance of the two? What if they were in raid0?

 

[Blayze]

doubt that would notice the difference in real world enviroment, but in benchmarks ATA100 would probably show up to be faster.

Well, you might if you were doing large file transfers and you were comparing a 5400rpm ATA66 to a 7200rpm ATA100.

 

[Pariah]

No difference at all. If you are RAID'ing, the drives should be on seperate channels which results in the same "no" answer.

I recently upgraded and havnt been able to tell a differance on the other hand I can say I have ATA100

 

[bjc112]

NOPE! !

 

[ragiepew]

you have to realize that today's drives, and tomorrows as well, cannot fill the entire bus so like everyone says... the answer is no. IDE drives currently top out at about ~40MB/s in sustained transfer rates and unless you have two of these (and on the same channel, something you should avoid if you can) you would still be under the 100MB/s spec... although you will be over the 66MB/s spec... but then again, when will you ever be using both drives @ the same time? Anyway, you shouldnt notice a difference unless you place both drives on the same channel and RAID them or something (something that will use both drives simultaneously(SP?)) and if you plan it right (ie. placing drives on different channels) you can avoid that problem as well.

No.

Take the analogy this way. Take the speed of your hard drive as how fast you can cycle, and the ATA speed as the speed limit.

If you can only cycle at 44km/h, raising the speed limit from 66km/h to 100km/h is not going to make any difference, is it?

I was under the impression that raiding improve hard disk performance in 0+1 mode as each hard disk will be accessed for a different part of data.
Hence if you raid it is like opening filling your gas tank with two pumps at the same time, it necessarily fills up faster. twice as fast in fact.

But maybe I'm wrong

ATA100,ATA66 and are burst speeds. Doesn't mean you'll be transfering at 100 or 66 MBs/sec. The part that really counts is the speed of the HD.

Well the reason i am asking is cause i don't use anywhere near enough of my 2x30gig Maxtors, ATA100, 7200RPM. So I was thinking of trading one of them for a couple of 15gig ATA66 7200RPM, just wanted to know if I would notice the differance, but I didn't think so. thanks
