"If I'm writing 10GB a day to AC*** 050-555 Exam a 120GB SSD, it will last over 10 years," Geiser said.
Unlike hard disk drives, all SSDs slow down after initial use because once a sufficient amount of data has been written to 050-555 Exam them, the processor in the drive begins to move data around -- a function known as the read-modify-erase-write (erase-write) cycle. So each time new data is written to the SSD, data must first be marked for deletion before new data can be written. Over time, the cells or transistors in NAND flash wear out due to 050-555 Exam the erase-write cycle.
SSD makers have increased the sophistication of error correction and 'wear leveling' software, which works to more evenly spread data 050-555 Exam writes across a drive so as to not "wear out" any block of cells more quickly than another. But, eventually they all wear out.
The SSD controller and the firmware is where error correction code (ECC) and wear-leveling take place.
