* In some cases, somewhat longer lifetime – Flash storage typically has a data lifetime on the order of 10 years before degradation. If data is periodically refreshed, it can store data indefinitely. Flash drives have limited endurance (typically, 100,000–300,000 write cycles), which, if a single block is written once per second, leads to failure in a few days at most. However, all flash drives employ a technique known as wear levelling, where writes are smoothly distributed over all blocks. This means that if one write occurs per second, and n is the number of writes before failure and m is the number of blocks on the disk, failure no longer occurs in n seconds, but in (n*m) seconds. Given that blocks are typically on the order of 1kb and an 8 GB disk will have 8,388,608 blocks (8*1024*1024*1024 / 1024), assuming only 100,000 write cycles this gives about 26,600 years before failure; remember also this is with one write per second for that entire time. In consumer level devices you can expect the drives data storage component to last roughly 10 years in normal use.

pretty awesome, only can wonder what seagate and WD have up their sleeve.
