I&#x27;ve been using BK&#x2F;BAM for my photos, it&#x27;s got 56GB of data in there and works great.  I cheat because I added a way to check things out that uses hardlinks instead copies and I can check out the whole tree in 6 seconds.  Doing the copy takes a lot longer: 9+ minutes.  Hardlinks rock.<p>On the commercial site there is a link to some BAM paper, take a look at that and maybe ask in the forum or irc if this gets lost.
