Hi All, After the woeful performance of my DroboFS (even with Jumbo Frame support) I am looking to convert an old PC into a Thunderbolt enabled raid server or DAS (or JBOD) and access it directly from my Sandybridge iMac via the Thunderbolt connection. I would then use the Drobo to back the server up. The 18TB Pegasus R6 is not available here in Australia and even if it was - it would be out of my budget. I would not be running the PC in target disc mode (I had considered making it a Hackintosh but also want the PC for 3d Studio Max work). What I need to know is - do I need a specific disc configuration of the raid on the server to not suffer bottlenecks or performance issues when accessing it directly from the iMac via the Thunderbolt connection? ie: a specific raid level, a dedicated raid controller rather than using motherboard raid control, chipsets, etc. The mobo I was considering is the Gigabyte Z77X-UP5 TH. Yeah, I know this is more a PC focused question and this is a Mac forum - but what better than to make subservient slaves of the PC's to the Mac rulers. I just don't want to spend my hard earned on a Thunderbolt enabled PC server if I can't connect at those speeds over the Thunderbolt connection directly from the iMac. Thanks for any assistance in advance.
