Which is not necessarily true.

Referring to http://www.heise.de/newsticker/meldung/83173 (German only,
sorry)

different manufacturers offer 32GByte (or more) Solidstate disks with a
SATA interface as a replacement for a HDD (albeit currently at a high
price). Transfer rates are reported to be more than 60 MByte/s and 32
MByte/s (Read/Write) with seek times of the order of .1ms (and an energy
consumption of much less than 1W).

The MTTF is reported to be much more than a million hours which puts it
at least into the same league than standard hard drives (they use a
special file system to spread the usage of blocks throughout the medium).

I'm not advocating that this will be the ultimate solution nor that it
is completely sane, however, using fragile hard disks is not sane either
 ;).

Cheers

Carsten
