I upgraded my macbook pro to an ssd drive. Now when I run backups they take much longer. I don't understand why? I am backing up from a 960 GB ssd to a 2 TB ioSafe drive, using Smart Update. With the old 1 TB disk backups typically took about 40 minutes. Now a backup takes over 3 hours!

Right now I have had a backup running for almost 3 hours. It reports (in round numbers) 1,600,000 of 2,600,000 files, 106,000 files copied, effective copy speed 73 MB/s, 676 GB evaluated 718 GB already up to date, 14.5 GB copied.

I would have expected backup performance to be blazingly fast, since reading the ssd should be fast and very little actually has to be copied...

Seems likely the destination is what's slow here, actually.
