I've been looking for a decent Thunderbolt based solution for my Mac mini server. I prefer a rack mountable solution. Organised from least to the most expensive, I've got the following candidates found: 4 bay 1U Thunderbolt Enc w/RAID - PC-PitStop Thunderbolt | USB3.0 | eSATA 1U rackmount 5x Drives HW Raid with LCD and DirectAir OWC Mercury Rack Pro + La Cie Thunderbolt adapter Netstor Rackmount 16-Bay My questions are: When using server grade HDD's are any of the above decent solutions? It is hard to find (independent) information on the net. Anybody have experience (good or bad) with the vendors? Other than the OWC, I don't know any of them. Are there alternatives I've not find? Remark Since it the above is to host shares managed with the OS X server, it is not an option to use a NAS solution.
