I get about 27MB/s from raid 1 (10 is about the same) so hopefully I can up the throughput to the speed of about one disk with sw raid. For kicks I did try raid 5 on it; 6.9MB/s made it hard to resist going to get the hammer, which is still a very attractive option. -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
