not quite. quoting from your reference: <quote> 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." </quote> 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! <snip> > > [0] > http://www.kingston.com/digitalmedia/beintheknow.asp?show=fe > http://www.sandisk.com/pdf/oem/WPaperWearLevelv1.0.pdf <snip> -- "Programming, an artform that fights back" Anuerin G.
