Jack, Most modern flash devices have cells that are writable at least 10 times that - 100,000 cycles is the minimum you will find. Better devices have even higher cycle counts.
DOM products have FLASH in them - Nobody said anything about DRAM. If they had DRAM they would have to be continuously powered. Products like Disk on Module that are designed as hard drive replacements usually have better wear leveling capability than standard USB "thumb drives", as the directory meta data update issue is well known. SSDs take this to another level by "over provisioning" which means including more capacity than is advertised so that they will have enough spare capacity to make it to their rated lifetime. For applications where fast access is required nothing can beat a FLASH based device. Part of the equation there involves unit life; if you use a FLASH based device in an environment with lots of writes then you expect to be replacing it on an accelerated schedule. The write and read throughput is far above what a conventional spinning disk can provide, although the capacities are far smaller.
