external RAID solutions for 4k
Hey everyone. First time, medium time.
I've seen a few forum topics similar to this but I wanted to put forward my hypothetical setup and see what others thought. I'm currently on a cheese grater Mac with JBOD as my storage setup. I'm going to be buying a maxed out 5k iMac soon, which means I'll finally be forced to start from scratch with storage instead of juggling disks all the time and archiving constantly.
My clients are mostly non-profits, with a few corporate clients here and there. None of them have asked for 4k delivery yet, but I know it will happen someday, and editing in 4k is just around the corner for me. I'm currently shooting with a C100 and GH4 and editing in Premiere. Projects are generally short documentary in style and I'm not doing any 3D fx or compositing. Some motion graphics in AE and color grading, but that's about it.
My goal is to have at least 6 TB available for active projects on a RAID 5 for redundancy. I want a RAID 0 setup for my backup drive with more space than that so that Time Machine can keep versions of my project folders. I've deleted an entire interview before by accident and my auto-backup deleted it as well since it wasn't versioned. I'll archive on SATA disks using a dual bay enclosure (already owned).
I'm pretty confident about the above criteria (although open to other suggestions), it's just the specific products and features that I'm unsure of. Below is what I'm currently considering, specifically:
Active projects in RAID 5: Promise Technology 8TB Pegasus2 R4 Thunderbolt 2 RAID Storage Array (http://www.bhphotovideo.com/c/product/1013099-REG/promise_technology_p2r...) - This would give me 6TB to work with in a hardware-controlled (I hear that's important?) RAID 5 and 4 bays which should improve speed. My main question is, forgetting about the importance of redundancy, will I notice a speed difference between a Thunderbolt 2 4-bay hardware-controlled RAID 5 and a USB 3 2-bay Raid 0 working at the level I am right now? Again, I recognize the other benefits to the Pegasus R4, but it's so pricey for such a small amount of space, especially if I'm not going to notice a speed difference working at my level.
Time Machine backup drive in RAID 0: WD My Book Duo 12TB (2 x 6TB) Two-Bay USB 3.0 RAID Array (http://www.bhphotovideo.com/c/product/1053138-REG/wd_wdblwe0120jch_nesn_...) - If I get a larger active projects drive, this will also have to grow. But if I stick with 6 TB of usable storage, is 12TB a good size to be happy with using Time Machine for several years? Also, I'm assuming there is no benefit to having a Thunderbolt 2 RAID as my backup drive.
With all that being said, the things I most want to avoid are defective enclosures and setups that have a tendency to disconnect the drives at random. For this reason I have not looked very hard at OWC's solutions, although their pricing is much more appealing for larger amounts of storage.
Any thoughts are welcome. Thanks!
