Curse of SSD

"The problem with an SSD is [that] data is written in blocks. A block may be 256KB: 256 * 1000 * 8 binary digits. To change even ONE of these digits, you must rewrite the ENTIRE block. That is to say, your OS sees 1 bit being written, but the SSD wear is equivalent to 256KB being written: a 2.048 MILLION fold difference." From here
