Don't know how long the drive would last. You somehow need to figure out how many GB of data will be written in one day.
With that info maybe someone (not me, I'm not that knowledgeable
) can extrapolate how long the drive will last.
Most consumer level SSD (including the Intel 320) use MLC NAND. Whatever drive you decide to buy should have SLC NAND, which have higher P/E cycles than MLC NAND, and will last longer.
