Doesn flash memory have a limited lifetime compared to DRAM?
If used in exactly the same ways, flash memory does have a shorter lifetime than DRAM. Gear6 Web Cache employs a number of techniques to address this issue. Internal caches within Gear6 Web Cache limit the number of times that flash access is required. Writing objects across flash boundaries is minimized. Gear6 Web Cache also constantly monitors both DRAM and flash memory in all cache modules, removing form service any blocks where failures have occurred, and proactively deactivating those where failures appear imminent or likely.
