Are there any recommended drives? We recently bought the Intel 311 for that purpose. This drive is quite cheap and should perform ok. If you want something better have a look at the 710 line. You should always mirror your ZIL drives. There's a lot of content available on this subject actually. I once read about a tool called zilstat which should help you decide if you do actually need a SSD. NFS and db's are the usual usecases. cherio, Leon
