IMHO, it puts no more wear on the drive than playing. I've ripped >1000 SACDs on my 103 and 105 and they are both still going strong. Besides, I have no need to "save" them because all I do with them is rip. I play only from the files.
If you rip it once, or play it twice, what do you think puts more "wear" on the player.
The Sony cost me $30 and I just prefer to use that to rip SACD since I read somewhere that the ripping process puts extra wear on the players. I only use my Oppos for blu-ray movie playback at this point, now that I've ripped nearly my entire collection of SACD, DVD-A and blu-ray, so I won't be playing any of those audio discs anymore. My 103 and 203 are still considered to be great blu-ray players so I like to use it as minimally as possible.
