Berkeley DB Family

I'm looking at using a server-grade solid-state-drive from Mtron as the primary BDB database directory. This should give me much better random-read performance, and the log file writing should be really fast.

Two questions:

1) does anyone have any experience with SSDs and BDB?

2) how does BDB do its disk writing, is it typically append-oriented, or is it fairly random-write oriented? This matters, because random-write performance with SSD is fairly slow, where as bulk-serial-writes are very fast on an SSD.
