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

Most flash controllers do have a reserve of blocks for bad block management so even if a block suffers a failure you might not notice as it will be remapped. I would think that though an individual block might have a life span of 100,000 writes (which is the low end of current hardware as I understand) it will be a very long time until the device runs out of reserve blocks.
