The title doesn't make sense.

Nonetheless, the technology is interesting.

But beyond use in enterprise server rooms, I don't see a need for this at the consumer level.

Are consumers really this impatient?]]>Jan 15th 2009 1:17PMhttp://www.engadget.com/2009/01/15/laser-hard-drives-boast-1tbits-s-access-time-doesnt-exist-yet/http://www.engadget.com/2009/01/15/laser-hard-drives-boast-1tbits-s-access-time-doesnt-exist-yet/

If it eliminates the spinning disc, or something spinning, would it not be considered similar to an ssd?]]>Jan 15th 2009 1:18PMhttp://www.engadget.com/2009/01/15/laser-hard-drives-boast-1tbits-s-access-time-doesnt-exist-yet/http://www.engadget.com/2009/01/15/laser-hard-drives-boast-1tbits-s-access-time-doesnt-exist-yet/Jan 15th 2009 1:25PMhttp://www.engadget.com/2009/01/15/laser-hard-drives-boast-1tbits-s-access-time-doesnt-exist-yet/http://www.engadget.com/2009/01/15/laser-hard-drives-boast-1tbits-s-access-time-doesnt-exist-yet/
Also, I seriously doubt it will have the same data density as CD. A higher density will allow it to read more data at the same physical speed. It is what they did with hdds, dvds, hd-dvds and blu-ray.

from the article :
"This future type of magnetic/optical hybrid will not only potentially be thousands of times faster than any existing magnetic storage technology, it could also remove the need for the rotating disk (platter) used by every hard drive since the original IBM 305 RAMAC in the mid 1950s."

Honest mistake when you write like a banshee on fire.

I wish everyone would get on the same page here and stop using bits, i have no way to relate to bits for speed... when I think of hard drive speeds, its in MB/s, and when i think of internet speeds, its in KB/s.

So, lets go to google, type in "1 terabit to megabytes"
we get 1 terabit = 131 072 megabytes

Sounds fun for me.]]>Jan 15th 2009 1:23PMhttp://www.engadget.com/2009/01/15/laser-hard-drives-boast-1tbits-s-access-time-doesnt-exist-yet/http://www.engadget.com/2009/01/15/laser-hard-drives-boast-1tbits-s-access-time-doesnt-exist-yet/
And for the bits thing... Just divide by 10.

Bytes are not that much more fun anyway:

Of course by the time this increases the speed of the last thing (HDD) the other items will also probably grow in speed.

>And who needs instant erasure and reset?

See above. As for large amounts of data trash, well, super computers for instance. There are computational processes that produce immense amounts of intermediate data and the ability to erase it in a glimpse after the process has ended can be extremely valuable if time and/or money play a role (which they usually do with large-scale systems).

>Flicking the switch is actually the most frequent reason for data corruption. Do not flick the switch, it will make all the evil spirits come.

In normal operation, yes. When a crash occurs, however, the CPU is halted and no disk operation can take place.]]>Jan 15th 2009 3:31PM
