I've been researching storage devices, and have decided to go with an eSATA unit with hardware RAID-5 built-in, mainly because the Mac Pro doesn't have enough PCIe slots to add a RAID card. I already need an eSATA card for a Red Station, so I might as well use one of those ports. I know that this greatly limits the choices, because most large RAIDs use an external controller, but I've found a few options:
Glyph ForteRAID $1000
OWC Mercury Rack Pro $1720
Sans Digital EliteRAID ER104UT+ $1820
Sans Digital EliteRAID ER208UT+ $2720EDIT: new contender G-TECH G-Speed Q $1600These prices include buying bare enterprise drives (4x3TB Ultrastars). The large Sans Digital would give me 4 empty bays to upgrade later...not sure if I need that. Other than that, I'm stumped as to why the Glyph unit is so cheap! I keep thinking it must have some major drawback, but what is it? It could be the drives; it does not specify whether they are enterprise drives, but I would almost assume that they are on a product like this. Or could it be a lousy controller? It's Oxford 936. One obvious downside is the Glyph isn't rackable, but that's a minor thing. Also, the Glyph Manager software doesn't work over eSATA (wtf?!) so you have to plug in USB to check system health or change RAID modes. OWC claims 300MB/s max (in RAID-0). Sans Digital claims only 200MB/s. Glyph claims 230MB/s. It seems like the only thing going for Sans Digital is its really nice monitoring interfaces. I'm leaning toward the OWC Mercury...Can anyone offer tips from experience with any of these units?Thanks.
