Especialy with seagate, i have bad experiences. Most of our
harddrives are malfunktioning within less then 4 years (24/7)!
But other brands are not much better ...
The problem with FlashROMs is that they can be re-written about
10000 times (some companies guaranty 100000 cycles).
Even if the FlashDiskDrive uses a special algorithm similar
to that of the WORM (Write once read multiple)-technique, so
that you can have about 1.000.000 cycles:
If every 10 seconds something is written to it, then the
livetime will be less then 2 weeks!
Consequently, Flasdisk are only for "static", ruggedized applications.
(i.e. routers, /tmp is mounted on a RamDisk and Configuration
is only saved on admins desire).
