Well, ram is more expensive per gigabyte than SSDs, particularly if you've got something with a battery attached - the idea would be to use your SSD for buffering 80 gb or so of writes, but then buffer all of bcache's metadata writes in battery backed-up ram, significantly decreasing the number of write IOPS to the SSD, and making it so pretty much all the writes to the SSD are big contiguous writes.
