Why SSDs Won't Replace Hard Drives

storagedude writes "Flash drive capacities have been expanding dramatically in recent years, but this article says that's about to change, in part because of the limits of current lithography technology. Meanwhile, disk drive densities will continue to grow, which the author says will mean many years before solid state drives replace hard drives — if they ever do. From the article: 'The bottom line is that there are limits to how small things can get with current technology. Flash densities are going to have data density growth problems, just as other storage technologies have had over the last 30 years. This should surprise no one. And the lithography problem for flash doesn't end there. Jeff Layton, Enterprise Technologist for HPC at Dell, notes that as lithography gets smaller, NAND has more and more troubles — the voltages don't decrease, so the probability of causing an accidental data corruption of a neighboring NAND goes up. "So at some point, you just can't reduce the size and hope to not have data corruption," notes Layton.'"

Why solid science reports won't replace churnalism

[A beautiful mind]

"Science reporting organizations have been expanding dramatically in recent years, but this article says that's about to change, in part because of the limits of current literacy education. Meanwhile, tabloid reporting will continue to grow, which the author says will mean many years before solid science reporting replaces sensationalism -- if they ever do. From the article: 'The bottom line is that there are limits to how smart things can get with current society. Universities are going to have student density growth problems, just as other societies have had over the last 30 years. This should surprise no one. And the literacy problem for journalism doesn't end there. Buff Clayton, Editor in chief for The Onion at Delaware, notes that as literacy gets smaller, science reporting has more and more troubles -- the bullshit PR releases don't decrease, so the probability of causing accidental sensationalism goes up. "So at some point, you just can't reduce the literacy and hope to not have reader confusion," notes Clayton.'"

Yes, but have you forgotten Isaac Asimov's corollary?

"When, however, the lay public rallies round an idea that is denounced by distinguished but elderly scientists and supports that idea with great fervor and emotion -- the distinguished but elderly scientists are then, after all, probably right".

Meant for someone else, but not for me.

Seek time? You're also forgetting the controller electronics too.

if you think 16TB is enough for the average home user you either severely overestimate or underestimate homeusers.

i don't know which, actually.
