does consolidate free space on SSD help?

[snadge]

I have PerfectDisk 12 setup to defrag my HDD. it has an SSD optimize function which it says consolidates free space and helps speed up write performance? im sure this doesnt help as SSD's read and write same speeds if the file is fragmented across the drive or not = so I fail to see how large amounts of contigous space on an SSD could be beneficial

anyone?

I don't think this has to do with defragmentation, but how a SSD uses free space on the drive. Before new data on a SSD can be written to a block any old data needs to be erased first, unlike HDD's which can just overwrite on top of the old data, which so say can result in performance loss. Consolidating the free space can reduce the amount of data that needs to be erased. Probably more useful for older SSD's without trimm/gc or those in a raid config where the trim command does not get passed on.
