that's fine.. i think firmware reserve SMALL part of media in non-shingled format as a log to keep small writes, and then in periods of low load it writes it for real. the chance of coalescing multiple writes gets high this way. seems fine for drive that is just used to do backups over net with rsync On Thu, 26 Mar 2015, B.

I understand average random write time would be 5-10 times slower than normal drive because of the need of rewrite few full tracks worth of data, but otherwise will then be compatible and can i use it as usual? >> _______________________________________________ >> freebsd-hackers@freebsd.org mailing list >> http://lists.freebsd.org/mailman/listinfo/freebsd-hackers >> To unsubscribe, send any mail to "freebsd-hackers-unsubscribe@freebsd.org" > >
