It's likely to stay that way for at least the next six months.

If you actually need a terabyte of storage for a PC, you'll be sorely
tempted to set up something called a RAID-0. That's two or more hard
disks connected to a controller, emulating a single, larger hard disk.
After all, if you've already filled 1TB, filling a second one isn't
that difficult.

Any standard SATA chip on a motherboard will do this, but most of them
don't support RAID-0 larger than 2099GB (2^41 bytes). Nor, in fact,
does Windows XP or Vista. The inability to "double up" hard disks like
this would, in my opinion, make a 1.25TB hard disk *less* useful than
a 1.00TB one.

WTF are you babbling on about?

The whole point of RAID-0 is that it fragments data across two drives to
allow faster data access - it's nothing to do with making two drives appear
as one (yes, that is a side-effect, but who needs a single 1TB one instead
of two 500Gb ones?) .In practise the gains are pretty small, and only of use
to a tiny minority of users, and the huge drawback is that if one drive
fails, you lose *all* your data.

Much more relevent for the average user is RAID-1, which duplicates the data
on both drives, meaning if one fails, you can carry on as if nothing
happened - though that does involve buying twice the storage space you need.
