The ada(4) driver now supports BIO_DELETE. For SSDs this uses TRIM feature of DATA SET MANAGEMENT command, as defined by ACS-2 specification working draft. For Compact Flash use CFA ERASE command, same as ad(4) does. This change realizes restoring write speed of SSDs which supports TRIM command by doing newfs -E /dev/ada1, for example.
If i'm not newfs'ing my partitions, will the write speed be restored after some time ?
Or can i just create a big file to fill empty sectors and then delete it ?
