XP and SSD's are fine, all current generation SSD's have GC (garbage collection) imbedded in the firmware, GC is the process of relocating existing data to new locations and allowing the surrounding invalid data to be erased. Flash memory is divided into blocks, and blocks are divided in pages. Data can be written directly into an empty page, but only whole blocks can be erased.
The advantage of the TRIM command is it enables the SSDs GC to disregard the invalid data and not move it, saves rewriting the invalid data. This reduces the number of erase cycles on the flash memory. The SSD doesnt need to immediately delete or GC these locations, just mark them as no longer valid.
