Hard Drives larger than the Seagate 750GB ?

I have several Maxtor 500 GB sata 2 drives, and poised to buy a Seagate
750GB

My question is this, are there any standalone non raid hard drives in the 1
Terabyte range that will hit US shores anytime soon?

Are there any online timlines for when one might see a Petabyte Hard drive.

Damn, I remember back in 1997 paying $400 for a 4 GB hard drive and back in
1995 paying about $200 for a 1.2 GB hard drive

Thnx

I remember paying $3000 for a 10 MB (yes, MegaByte) drive.

That might take a while. The technology used in the 750GB drives is
quite new and I don't think they can actually add more platters.

Not anytime soon. An there is a problem: Transfer rates are not
keeping up. Example: I have some older 80GB maxtors. Theu give
me an average 30MB/s r/w rate (or so), i.e. 45 min to read or
write the whole disk. Recent 500GB drives I have give me about
60MB/s r/w rate (whole disk, not just the fast area at the start),
i.e. 2 1/2 h to read or write the whole disk. If this rate keeps up,
then the petabyte disk will have a r/w rate of about 1GB/s, i.e.
will take about 12 days to be read or written completely just once.

Seems to me data density is not the only problem here....

Why do we need bigger hard disks? Because hard disks tend to fill up
too fast. As least with those, we know that they'll take at least
12 days to fill up.

Well, we may be able to get a 1.2 TB hard drive for $200 in 2007 or
2008, i.e. 12 or 13 years later. That's a long time.
If the same curve stays, we may be able to get a 1 PB hard drive at a
decent price around 2020.

However, AFAIK, in those 12 years, the technology didn't change much
-- a bit is still represented the same way, only smaller, allowing for
more bits to be stored on one square inch.
A year ago, they managed to make a little change (storing the bits
vertically instead of horizontally), that may allow hard drives to get
past the TB line. But I doubt that this technology will allow more
than a few terabytes in a 3"1/2 hard drive.
