I still don't "like" how the ATTO graphs look for my Perc 6i.... I mean, for all the other ones posted here -the LSI, 3Ware and even that adaptec (despite is Raid 0-ness, lol grinder)- all have steadily increasing read/write #s as the data size moves up. But on my ATTO graph I get some drop offs for writing at 128k, 4Mb and 8Mb. I guess I don't understand enough about how the raid cards works (and sorry that i keep straying further and further off topic jdrom17) but i really want to understand the inconsistencies here. Any help guys?
