And it takes 3 weeks to seek from one end of the tape to the other...
[QUOTE=S31-Syntax;52532387]And it takes 3 weeks to seek from one end of the tape to the other...[/QUOTE] About 2 minutes, actually.
[QUOTE=Paul-Simon;52532398]About 2 minutes, actually.[/QUOTE] That is really impressive for a data tape, especially considering the capacity.
[QUOTE=S31-Syntax;52532405]That is really impressive for a data tape, especially considering the capacity.[/QUOTE] And while it's hardly "expedient" compared to hard disk and solid state memory, 330TB on something twice as small as your average hard drive is still very impressive.
[QUOTE=S31-Syntax;52532405]That is really impressive for a data tape, especially considering the capacity.[/QUOTE] Yeah, remember that the real big news here is [I]data density[/I], and not really [I]total storage.[/I] They could've made a tape drive with this capacity 10, 20 or 30 years ago, but it would have been physically massive and have seek times of days and weeks.

They crammed several hundred TBs into something the size of an ipod hard drive, its really damn impressive stuff.

[QUOTE=Asgard;52533192]Truer than ever[/QUOTE] Hell, get a carrier pigeon to carry one of those babies and you'll beat the transfer speeds of most American ISPs.
[QUOTE=Paul-Simon;52532398]About 2 minutes, actually.[/QUOTE] So 2.75 TB/s? Christ that's impressive as long as the computer reading it can buffer all of that.
[QUOTE=Sombrero;52537532]So 2.75 TB/s? Christ that's impressive as long as the computer reading it can buffer all of that.[/QUOTE] Seeking is not the same as reading - 2 minutes is just the time to go from end to end. The equivalent hard drive action would just be it flinging its head from the outer rim to the inside.
Well at least it postpone's LTO's death for 7 more years.
What's the average life expectency on this type of storage though? :s:
