>From section 14.17.2 of the FAQ: "Write fatigue": Much has been written about the finite number of times an individual flash cell can be rewritten before failure. Practically speaking, however, there are many ways a flash device can fail, write fatigue is just one of them. Modern flash devices will verify writes, and in the event of failure, will automatically remap the failed sectors with one of the many spare sectors. Most users with most flash devices will not have to worry about "write fatigue". You would probably experience more down time due to failure of "clever" tricks done to avoid writing to the flash drive than you will by just using the drives as read-write media.
