OK I see the need for new long acronym-ed technologies to step in and help lengthen the life of the thick silver platter.

So how is this fundamentally different from when we moved from 1Gb to 4Gb hard disks back over a decade ago? hard disks have hit about 1Tb now havent they, so why is 4Tb in one HDD such a difficult thing requiring new double TLAs?

I don't remember it taking a good two years to achieve that leap. But then I could be wrong.

Or is it that the old spinny disks days are numbered due to flash RAMs much higher rate of capacity climb. I know they're only on 64Gb commercially now but have been climbing really quickly since around 2000 up from a lowly 16Mb!!

Thanks Tony.

Begs the question why there arent 5 1/4 inch hard disk drives specifically for PCs around then, but I would imagine that physically increasing drive sizes results in diminishing returns of performance, efficiency, and even capacity.

I was just surprised that Hitachi reckon it'll be a whole two years delay given development was quicker in the past.

Strange that the BBC reported the same story, different angle, but said they'd arrive in 2011, go figure!

...we need to get rid of hard drives altogether.

I mean, c'mon. You open up the case of an ordinary desktop computer, and what do you see inside? Miracles of solid-state electronics, with circuits etched into silicon so small that quantum effects become a real engineering headache for the folks who design them...and then this big, whirring, spinning piece of antique Victorian clockwork.

It's appalling and embarrassing, really. Spinning disks of magnetic media? We need to chuck the clockwork already and move on to solid-state mass storage.

Solid state is sweet, but it's expensive as all hell. And, with fabs at or near capacity, just increasing demand isn't going to lower prices for a while at least. I'm all for solid state, but not if it's going to cost me like $2000 to get a TB of storage...

With the advent of holographic memory, this is purely a "We can do this, just watch us!" scenario?

I thought they were dealing with holo-memory for the future? With a possible (theoretical without error correction) 4Gb per millimeter, surely "it's the future!" (Garlic Bread anyone?)

Paris, Paris, Paris!... ahem..

to bring this up but WTF apparently in the US they are deciding whether to block imports of the top hdd manufacturers because of a patent being used without permission in the fabrication process anyway the one thats not being mentioned is Hitachi and all I have seen for the last couple of days are Hitachi commercials if they do block Seagate Western Digital it might mean cheap hdd

s for all outside the USA. I didn't make this up it's been in Ars Technica and on the USITC site.
