I have a great suggestion for you to look into. I wouldn't suggest RAID 1 either because what you gain in speed, you lose in protection. Why back up only to lose it all- right?
Look at Drobo. a tad expensive but fast, protected, hot swappable, gives you notice when a drive will fail, if a drive fails, all data is saved on other disks. When you fill up the drives, replace with bigger ones. If you max out Drobo (possible, but with capacious drives, hard to imagine at this point) you can daisy chain them. There are a good number to choose from.
I have been using mine a couple of years and love it. It is easy to set up. Additionally, you can start with two drives and add more when you get more $$. It is a lot easier than the setup you describe (I have tried NAS before and they can be a pain to set up and keep up). I am on Mac's and no problem.
I would finally suggest that you keep your Macbook clean and simple. Just keep your programs on there and keep you pics etc. on the Drobo. With fast drives in the Drobo, you shouldn't have a problem doing intensive editing.
Hope this helps.
My set up:
macbook pro (late 2011 model, 16GB ram), Dell U2711 monitor.
Now, as you can imagine, shooting all RAW, making multiple versions of some images in Post...and doing lots of video, editing it...versions after color grading, etc.
Well, I'm eating LOTS of disk space...that's not even keeping in mind, the software I've installed on said computer (aperture, fcpx, plugins, VMware, GIMP...etc, etc).
I'm having a terrible time keeping disk space open. As soon as I finish a project, I just move all the files off to an external single drive I plug into a USB connected drive docking station.
I'm thinking that I need some sort of fairly speedy, maybe dual disk NAS type thing....? Maybe do it RAID 1 (mirrored) there.
I'm trying to fix up a separate computer to build a freeNAS system for large backups, haven't gotten that up and running yet, but I think for right now...I just need a large, fast disk storage system for holding and working on my current few projects.
Does anyone have a suggestion for that?
My macbookpro, has one thunderbolt connector on it...I'd think that would be the way to go, however, I'm using that with a thunderbolt to displayport cable/adapter...to run the Dell U2711 monitor, and I don't think there is a way to chain off that...?
So, likely firewire or sadly, USB2 is about my only option for connecting....
Anyway, does anyone have a suggestion on what I might look towards?
Thanks in advance!!
