Hi I've got a 2010 Mac Pro and way too much data that I need a better way to store. It's basically all photos (RAW) and videos (compressed). Currently I'm using two internal 2TB mirror RAID arrays, but those are filling up so I need a new system. I'm considering several options: external raid enclosure via eSATA, external NAS enclosure, Linux file server, or an internal solution like the transintl DX4 that lets you mount SSDs below your drive sleds. Part of the reason I'm considering the DX4, and if suppose why some of this is so complicated, is that I also want to upgrade my primary drive to SSDs in a RAID-0 stripe configuration. I already backup my main volume to both a superduper clone and a time machine drive. Out of all the storage options I've listed the only one I've actually tried is the Linux file server. I built a server a while ago to attempt to use for this purpose. It works pretty well, and it can certainly grow to the desired capacity, but I dont think it's the right way to go. The server's motherboard died about a month ago, and while I didn't lose any data, I did learn that I don't like playing sysadmin while my data is on the line. Currently everything on the server is mirrored elsewhere, so maybe this is the right solution to use as a backup a volume for whatever my primary storage device is. So basically I am looking for advice from anyone who has used some of these mass storage devices to help me figure out what would set suit my needs. So what are my needs? I'm a developer my day and a photographer by night. I need a fast volume for doing current work (scratch) with Aperture and Xcode, and a massive storage volume for keeping my older projects and pictures. I use Aperture in a referenced library configuration, so the library itself lives on my main drive (hopefully an SSD soon) and the RAW files live on the RAID. If I get a large enough stripped SSD then I would probably keep working files there and move them off to the RAID after editing. So performance on the storage system should be good but it doesnt need to be outstanding. Anything over 90MB/s is probably fine. I'm also looking for any advice on SSDs, on the DX4, and even any stories from people using Aperture in situations like these. This is a pretty complicated problem I think, because it will also need to include a backup or archival system. We all know that RAID != backup. Anyways, thanks for reading. Merry Christmas and let me know if you can help.
