OK. Thanks for answers.
So i need LSI Megaraid series card for my needs? 9240-4i is the entry line. That should be able to give me the sequentials what i am looking for?
Im really dissapointed about lack of information on LSI 9211 series raid cards. I mean, why do they even make those HBA cards at sata3 if they are not even close to the sata3 speed requiements. And there is ZERO information about the limitation on their page.
Honestly. I starting to look some other brand now. This is discrace for LSI.
Silly me. I should have asked here, before i bought it. All info i found in forums and other pages suggested that 9211-4i is up to its task with 4x c300. Now i know, it clearly isnt!!!
