mam nadzieję, że o to chodzi i było by świetnie. Ale trzeba by było to sprawdzić fizycznie.
z opisu wynika, że trim/wiper robi coś takiego - zbiera dane z “pustych” i “wykasowanych” miejsc, zbiera to w jeden plik i kasuje, dzięki czemu oczyszcza i przyspiesza działanie SSD
tu po angielsku, ale myślę, ze zrozumiale

TRIM is an upcoming drive controller command meant to inform a solid state drive (SSD) of free space, so that the drive may be preemptively defragmented to increase performance.[1]
SSD defragmentation is a very different process, with different causes, than a spindle HDD defragmentation. Regular defragmentation tools do not work with SSD as they are meant to solve different issues with the storage of data. The root cause of the issue is that SSD drives cannot actually modify data without first deleting it. Furthermore, SSDs can write 4kb blocks at a time, but only delete 512kb blocks, often requiring a read-erase-modify-write cycle instead of just a write operation. To avoid unnecessary work and slowdowns, spindle drives are only informed of data having been erased when they are told to modify the contents of the sectors containing it, not when the user actually deletes the data. On the other hand, preemptively erasing unused SSD blocks allows new data to be written without having to read, erase and modify existing data, greatly improving speed. By informing the controller of “free space”, data can be erased in preparation for future writes.
TRIM has already been implemented in Windows 7 release candidate, but until solid state drives are updated with firmware that can understand the command, it will simply be ignored.
Some drives (such as the Gskill Falcon and the OCZ Vertex) have a specialized tool called wiper.exe that claims to use TRIM on demand. However, it is actually a specialized defragmentation tool for SSDs (regular defragmentation tools do not work on SSDs).[2] It simply clears unused space, while TRIM actually informs the controller about unused space, allowing the controller to continuously manage resources for best performance.
