I think I reached the limit on my ivoge flash drive in about year... now
the first part of the drive is unreadable
thus rendering it useless.... I should have gone for a 2.5" HD usb
enclosure... a little too late hehehe

not quite. quoting from your reference:

According to Toshiba, the inventor of Flash memory and one of the top
suppliers of Flash memory chips, "the 10,000 cycles of MLC
[Multi-Level Cell] NAND is more than sufficient for a wide range of
consumer applications, from storing documents to digital photos. For
example, if a 256-MB MLC NAND Flash-based card can typically store 250
pictures from a 4-megapixel camera (a conservative estimate), its
10,000 write/erase cycles, combined with wear-leveling algorithms in
the controller, will enable the user to store and/or view
approximately 2.5 million pictures within the expected useful life of
the card."
For USB flash drives, Toshiba calculated that a 10,000 write cycle
endurance would enable customers to "completely write and erase the
entire contents once per day for 27 years, well beyond the life of the
hardware."

the study was for devices which does not write that frequently. put
that kind of storage for something like a browser cache, or a mail
spool (or anything that writes small files frequently) and you might
hit the limit pretty quickly. unless i misunderstood the gist of this
thread. :D
ciao!
