Like to hear some feedback from you guys..
I still use encfs for that. It seems to be some performance hit, but thats to be expected for FUSE filesystems. I´d like to migrate to ecryptfs. I am not to sure about block based approach on SSDs, but then I heard dm-crypt can pass-through trim requests - although there is a blog that this has its own share of issues somewhere. So for dm-crypt there are others to advice better than I. But I do recommend switching reiserfs 3 to ext4 for example. Now if you use reiser4, but I wouldn´t recommend this either. Not primarily cause of the fame of reiserfs 3 being a data eater - I never seen reiserfs corrupting data myself, however I did not use it for long. But: 1) ReiserFS 3 is not actively developed anymore. Reiser 4 is unlikely to become a part of the official Linux kernel IMHO. 2) ReiserFS 3 has high mount times on large partitions. 3) ReiserFS 3 AFAIK does not distinguish between data structures of *different* ReiserFS filesystems. So when you have a ReiserFS fs that carries a virtual machine image file with ReiserFS in the guest as well, it may well be, that a fsck on the host will mix up the filesystems altogether and break more than it repairs. I also think that performance wise it doesn´t make sense to use ReiserFS 3 anymore.
