Flash memories are available with two different kinds of memory density: SLC (Single-Level Cell) and MLC (Multiple-Level Cell). It can be manufactured under two different technologies, NAND and NOR. The type used on all devices listed above is NAND, and therefore you can see some manufacturers calling flash memory as “NAND”. NOR technology allows running program code and is basically used on cell phones.
It will depend on the number of write/erase cycles the person performs a day. If we assume that an average person will write 50 GB per day every day, a 64 GB MLC drive would last 35 years (64 GB x 10,000 / 50 GB / 365 days) and a 64 GB SLC drive would last 350 years (64 GB x 100,000 / 50 GB / 365 days). Of course for MLC-based SSD's with a maximum write/erase cycle lower than 10,000, you will need to adjust the math.
depending on the application you will write way more than 50 GB per day (for example servers), drastically lowering the life-span of the unit. That is why for the enterprise environment (i.e., servers) the kind of SSD that must be used is the SLC. So SLC-based units are classified as enterprise class, while MLC-based units are classified as consumer class

The difference between stupidity and genius is that genius has its limits.
