Recompressing .bsa archives (The Elder Scrolls 5: Skyrim)

Hi all!
As far as I know, using BSAopt to perestat archives of Skyrim, to save space on the drive, but I did not understand - whether it will adversely affect the game itself? Climb angloyazychnyj forums, because in Russian I have not found any information, and on some forums they say that nothing bad will happen and you can easily compress, while others cause crashes. Who to believe?

I need to peresdat them because I'm going to move the game to SSD, which free space is left exactly half (64 GB to 128), but afraid that there will be departures. Whether the departures from recompress archives? There are those who have experimented with compression?

Thanks in advance!
