Which drive would be faster for copying files a 7200 RPM ATA 66 or a 5400 ATA 100?

Thanks,

Heh, what do you personally think about it, Clovis?

Post, we'll do the "search"... :wink:

The 7200 would be the faster disk due to rpms. Data transfer on the ATA100 wouldn't make up for the rpms gain.

<font color=blue>The 7200Rpm ATA66 drive is going to be faster because the seek time (latency) is going to be better.</font color=blue>

<font color=green>With the ATA100 Hard drive you aren't going to get much better then ATA66 transfers.</font color=green>

What's with you and the colors all of a sudden, Lars?

The question is, what kind of files? Large ones, small ones. Blue ones, yellow ones.

Here is a comparison of Seek Times between the two drives <A HREF="http://www.seagate.com/cda/products/discsales/desktop/" target="_new">7200 ATA-66/5400 ATA-100</A>. This is just my opinion the the 7200 rpm (8.2 seek) would be faster, but the 5400 rpm (8.9 seek) would be quieter, practically thinking.

I compared the 20 GB HDD's 7200/66-vs-54/100 as reference.

it'll depend entirely on the specific drives. 7200 rpm will have a faster seek time for sure, but if you're copying big contiguous files, you need squential read speed, and there are some decent 5400rpm drives out there now.

I don't think either will sustain even 66 MB/sec - seagate's new cheetah 15000rpm drive pushes out about 50MB/sec over scsi... (www.linuxhardware.org)

probably the 7200 rpm drive will be faster overall, as it can get to the files (or fragments) faster, but for pre-cached files, the 5400/100 will be able to burst them faster.

I just compared a couple of drives on Seagates site, and an older 7200/66 had an avg transfer rate of 30MB/sec, while a newer 5400/100 scored 14.5MB/sec.

I'd go for the 7200rpm.

It seems to make it stand out, don't you think? I think it looks good. But I can stop, I was just being weird.

It doesn't bother me, except for the fact that your posts stand out more than mine :) 

I just never saw a reason that you started doing it. No big deal.
