1. Comment - Samsung Builds Flash Based Disk Drive

   (May 24, 2005 - 4:24 PM)

   If the filesystem and/or the flash drive's firmware is designed carefully, and distributes writes evenly across all of the flash disk's blocks, then its life can be extended enough that it is for all practical purposes infinite.
   
   However, if one were to treat a flash drive as a normal hard drive, frequently overwriting certain blocks that had often-modified files, one could "burn out" parts of the disk long before the manufacturer's specs.
   
   I'm guessing modern flash drives dynamically remap physical blocks to logical blocks based on frequency of writes to the logical block. (Where the drives store THIS information is another matter entirely ... perhaps they have an onboard SRAM and battery for this purpose.)
