Will these be as fast as SSD's?

At sequential transfers, for that data density, sure.
Random access still has the seek problem, though. In fact, positioning your head to a track that's 10nm wide might be difficult... I'm guessing tracks will be wider than that.

great, i'll be able to fit my pr0n collection onto two or three drives!
Re: News - Hitachi develops tech required to build 24GB HDDs
Hmm, maybe I'll hold off replacing my 3 1.5Tb drives in my RAID array ;) 3x24Tb (48Tb RAID5) sounds good to me ;)

The rebuild times would be crazy with drives that big. RAID6, RAIDZ2 or even RAID1 across three drives would be a little bit safer.
Minor nitpick: Tb != TB.
Re: News - Hitachi develops tech required to build 24GB HDDs
Definitely RAID-6/Z2 for disks that large. Chances of an unrecoverable read error on another disk during a resilver would be too high for my liking otherwise.

I believe on disks that large with current unrecoverable bit error rates for consumer HDD's, an unrecoverable error on restore is actually more likely than not!

This'll be a nice stop-gap between now and holographic (if and when). (Reminds me a bit of Red-Eye.)
