![]() Trim and garbage collection can work together to improve SSD performance and endurance by freeing up used blocks. The read-modify-write cycle also causes write amplification, which hurts the SSD's overall endurance. The read-modify-write cycle hurts the SSD's overall performance because it must now do three operations instead of a single operation. ![]() In order to write new data to used blocks, the SSD is forced to perform a read-modify-write cycle. Over time, most of the empty blocks will become used blocks that contain user data. ![]() When your SSD is fresh out of the box, all of the NAND blocks are empty so the SSD can write new data to the empty blocks in a single operation. ![]() Trim and garbage collection are technologies that modern SSDs incorporate to improve both their performance and endurance. ![]()
