TRIM
Made of millions of NAND flash cells, SSD can be written into groups called pages in 4K size generally, but
can only be erased in larger groups called blocks of 128 pages or 512KB. These stipulations are partially the
source of many performance issues. Until an address gets used again, the SSD has to keep track of every
last bit of data that’s written on it. The ATA-TRIM instruction tilts the balance in favor of the SSD. TRIM
addresses a major part of the performance degradation issue over time that plagues all SSDs. A TRIM
enabled drive running an OS with TRIM support will stay closer to its peak performance over time.
