400GB drive. So?
Thursday, Mar 11, 2004
A lot of tech blogs are linking to news of Toshiba's new 400GB hard disk drive.

So what?

Maybe living in internet time has jaded me, but back in 1995 I got a 1 gig drive for $700 and frankly I thought it was the shiznit. A few years later drives bloomed so large that I could take the 'the' and 'zni' out of my former opinion, because 1 gig was suddenly very old hat.

Since then, and well before, hard drive sizes have followed Moore's Curve (not Moore's Law, since that has to do with transistors on a microchip, but the curve is the same). Hard drive capacities at a given price point double every 12 months.

It's been true since I got my 5meg (yeah, meg) serial drive for my Mac 128K in 1985, and it was true until over two years ago, when 200 gig drives were mainstream.

Some time in the last two years, however, Moore seems to be slacking off, and what's more, nobody seems to be talking about it. So why the buzz over a 400 gig, 7200rpm drive? There are already plenty of 7200rpm drives out there (heck, there are 10,000rpm drives at Fry's), and 400 megs is just incremental over the 300gig drives on sale all over the place.

Where's my terabyte drive?
