Extend the life of your SSD drive with fstrim

opensource.com - Wed, 02/12/2020 - 16:02

Over the past decade, solid-state drives (SSD) have brought about a new way of managing storage. SSDs have benefits like silent and cooler operation and a faster interface spec, compared to their elder spinning ancestors. Of course, new technology brings with it new methods of maintenance and management. SSDs have a feature called TRIM. This is essentially a method for reclaiming unused blocks on the device, which may have been previously written, but no longer contain valid data and therefore, can be returned to the general storage pool for reuse.
