And on the particular SSD vendor (really the firmware), when it receives the (SATA) TRIM, or the (SAS) UNMAP command. Some of the firmware implementations can actually perform quite badly when told to reclaim (especially) large chunks, and they go into extended GC operations. These performance issues are more likely to manifest themselves in commodity SSDs than the enterprise ones, but, as always, YMWV.
