Now that we have a jumping point to get more than
2 TB in a single drive, what is the next limit of
capacity in hard drives?
Thanks,
Lynn

16 exabytes
That's the NTFS theoretical limit (not a lower limit that may be imposed
within the Windows). You never mentioned a file system. exFAT and
other file systems have different limits.

There will be a LBA48 linit at 1EB, assuming 4096k sectors.
It affects (S)ATA deives.
SCSI (and hence USB storage) is good for 64ZB with 4K sectors.
The latter is also the limit on GPT with 4k sectors.
Other limits are pure filesystem-limits, but given the stupidity
we have seen from Microsoft in the past, they doubtlessly
have some other limits in there somewhere.

Well, we will never need a drive capacity of
16 billion gigabytes. Right?

Right?
Well, if the sales folks have their way, all of us just must have
in-cloud storage of, ahem, unlimited capacity (providing we can fork
out the money for all of it).
As what was once sci-fi is being researched (started 10 years ago):
holographic storage. See:
http://www.colossalstorage.net/3d_holo.htm
http://en.wikipedia.org/wiki/Holographic_data_storage
So big, really big, file systems may be needed and not that many years
from now (well, in maybe a decade).

I may never live long enough to need 16 billion Gigabytes of disk space,
but maybe in a generation or two....
My first computer (an Osborne 1) had 64K of RAM and two 92K floppy
drives, and when I saw an outboard 5MB hard-drive box for it I thought,
"If only I could afford one of those, I'd never need to buy any more
floppies"!!!
Whatever you consider to be a reasonable amount of storage, somebody
will come up with programs that need twice as much. Think of Parkinson's
Law, rewritten for computing: "Programs and their data expand to fill
completely the space available for their storage."

Not for any current applications, that is for sure. I mean, what
do ordinary people evenneed 3TB for, if not video? And you
can already get a few 100 hours in good wuality on one.
But I am sure the industry will find some content for that
in the time of our children (or later).

The NSA can always use more storage... They'll juste rotate the
captures less frequently.

Are you talking about hardware-technology limits?
3.5" drives are at a plateau of approx 4 TB.
If HAMR gets off the ground, we could at least double that.
Maybe 10 x eventually, so 40 TB drives.
Hopefully, SATA transfer rates also double, quadruple by then.

And the reputed holographic storage devices
starting at 10 PB.

You mean those we have kept hearing about for the last 20 years
or so? I don't think they will materialize this century...

Yes and Maybe.

500 GB per cartridge. The drive is $50,000
but holds 15 cartridges. Read/Write rate of
20 MBps.
No Petabytes. Bummer.
