Thank you! Thank the devs more of course ;)

My world depends on writing TBs of data to micro SD cards in difficult environments right at the limit of write speed. These tools are great but our devices are linux (embedded), so this really is a huge help.

For anyone else out there who needs high performance out of an SD card... fstrim is your friend. Seriously, nothing comes close. Run it regularly when not under load.
