Flash Hard Drives

[Earle Beason]

    There are several companies that make solid state hard drives, I was 
able to play around the samples, they seem to respond quicker then the 
disc hard drives.

     I had a concern on the sustainability of memory over the lifespan 
of the device, most flash chips I am aware of have a read/write life 
span of 100,000 cycles. I am just wondering how long will it actually 
last before their is a failure

     I notice that that if I had something programed on to the flash 
hard drive to perform a specific function at a certain time every day,  
then deleted the program. It some how remained in the memory and 
continued to execute the specific function. Anybody have a clue on what 
might cause it? Bear in mind, the program is no longer visible the "LS" 
command
