Here on my desktop i've a software raid5 which makes 130MB/s too (3 disks). So to saturate the raid i've to put the encryption below the SW raid. Otherwise i'd only get arround 90MB/s. cu, michael -- It's already too late! --------------------------------------------------------------------- dm-crypt mailing list - http://www.saout.de/misc/dm-crypt/ To unsubscribe, e-mail: dm-crypt-unsubscribe@xxxxxxxx For additional commands, e-mail: dm-crypt-help@xxxxxxxx
