As the system adds files to the SSD, it reads the status of the NAND cells if it already has a data or it is already in an erased state. So, if we take this thought further - a brand new SSD has all its cells in erased state. Thus, a cell is "available" to store data if it is only in an erased state. Before data is written, it needs to perform an erase procedure on the cell. Data are stored on individual NAND cells. Although the comment is just in passing and majority of our System Engineers had ignored this statement since we are using Flash Arrays, the Engineer in me has made me to investigate the TRIM function.Īn SSD (Solid State Drive) is comprised of Flash Memory based on a NAND component. It has come to my attention when one of the NoSQL vendors - Couchbase - suggested to turn on the TRIM function in Linux for the internal SSDs as they claim it benefits the write speed of Couchbase server. Recently, I have been involved on projects related to Big Data covering Hadoop and NoSQL implementations. # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # Accessible filesystems, by reference, are maintained under '/dev/disk' # Created by anaconda on Sun Jul 19 02:29:21 2015

Windows 8 and higher, expands TRIM support on PCIe only for NVMe flash Drives. NOTE: Windows 7 and Windows 2008 R2 supports TRIM only on SATA SSD.
