Writeboost batches number of writes into a log (that is 512KB large) and submits to SSD which maximizes the throughput and the lifetime of the SSD.
Does this mean that dm-writeboost is similar to btier ? If so, this makes me wonder which of these two subsystems would be the best candidate for upstream inclusion. As far as I know btier doesn't split bio's. The source code of btier can be downloaded from http://sourceforge.net/projects/tier/.
