TimeMachine encryption performance: Synology's vs. Mac OS X's

A quick experiment to see what is faster to encrypt a TimeMachine network volume: using Synology's folder encryption or OS X's automatic TM encryption. Copying a directory with 1200 files and directories in it (source files and compilation products), about 125 MB in total: Unencrypted: 86 sec Synology's encryption: 90 sec OS X's encryption: 10 sec So, not much to discuss about it: OS X's encryption wins. Notes: This was done by the verily scientific method of trying a couple of times and counting seconds aloud. At the beginning I was thinking about doing it in some scripted, repeatable, strict way to control for things like caching and blah blah. But, a 1:9 difference? That's convincing enough for me, kthxbai. I simulated OS X's TM encryption by creating an encrypted disk image (AES 256 bit, sparsebundle) in an unencrypted folder in the Synology's server. This might not be the same than the real TM encryption, since that seems to be done by F
