This is interesting, I know SCSI does not have this limit, since there is a 181GB Cuda http://macgurus.com/infopop/emoticons/icon_smile.gif

<BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR>With capacities that double roughly every 12 months, hard drives have a long history of outgrowing other technologies around them. Many of the roadblocks in capacity have had to do with limitations in the operating system or the PC's low-level basic input/output system (BIOS) software, which prevented the systems from recognizing drives larger than a certain size. But the latest capacity snag results from the ATA standard for locating information on a hard drive. Using a 28-bit addressing system, today's ATA interface can track up to 137.4GB.

Drafts for the latest ATA standard, version 6, include a proposal to increase the addressing system from 28 bits to 48 bits. That will increase the maximum possible hard drive capacity more than a millionfold from 137.4GB to 144 petabytes (a petabyte equals 1 million gigabytes).<HR></BLOCKQUOTE>

I can not count that high http://macgurus.com/infopop/emoticons/icon_redface.gif

Hey, what do SCSI drives use internally?

Huh...I wish I had the desire and courage to admit to the world that I wanted to record the entire Seinfeld series on a hard drive. I wish I had that kinda time on my hands to pick a TV show to record every episode of. http://macgurus.com/infopop/emoticons/icon_biggrin.gif

I do like the point about the speed and capacity of today's machines being more than the average user can actually use.

I would be more than interested in a SCSI drive employing Seagate's new SoftSonic (http://www.seagate.com/cda/newsinfo/newsroom/releases/article/0,,1156,00.html) technology.

it doesn't seem to be listed on the seagate web page, but the barracuda iv (the drive dsm's link refers to) has the following serial numbers, according to this online seller: www.alstarshop.com (http://www.alstarshop.com) (hope this isnt a conflict of interest)

ST360021A 60GB $159
ST380021A 80GB $195

Both are 7200 rpm ata/100s. should be more than sufficient to saturate my beige g3 ata/33 channels. rather cheap too. hmmmm....
