Backups *slower* with ssd?

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...
