- The SSD then evaluates each range, if it is already tagged as trimmed, there is nothing to do. If it is currently tagged as in use, it tags it stale/unallocated. At that point, the garbage collector can start to do it's thing.
Since all that is happening is flags are being updated for the benefit of the garbage collector, it is extremely fast and it really doesn't add any wear and tear to run fstrim nightly.
It in fact prevents wear, since it lets the firmware spread the writes better. That's the whole reason I always include the discard whenever dealing with flash-like storage. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
