Do Solid State Drives Slow Down Over Time?

Do Solid State Drives Slow Down Over Time?: "a SSD uses no moving parts, compared to the electro-mechanical disks used by traditional hard drives. As a result, they start up more quickly, not requiring any spin-up, use less power, are quieter and more rugged, and—most importantly—are faster.

SSDs can utilize either DRAM volatile or NAND non-volatile memory, that is, memory that either requires or does not require power to retain data. For example, a popular non-volatile SSD drive is simply a flash or jump drive, which can be connected and disconnected from power—i.e., a computer—without losing its data.

So what's the catch? Unlike hard drives, SSDs require that the old data be erased before new data is written over it, instead of just writing over the old information. This doubling of wear leads to some serious issues:"
