Hi, I'm sorry if this has been discussed, it's my first real post and although I found info about all these things everything I find is scattered or littered with misinformation. I'm hoping some people that have experience and knowledge with this might be willing to reply and shed some light for me. I have 4 drives in Mac Pro: 750GB Seagate 7200.11 32MB Cache SATAII (2 days old) 500GB Western Digital SE16 16MB Cache SATAII (1 year old) 500GB Western Digital SE16 16MB Cache SATAII (1 year old) 320GB Western Digital SE16 (Apple Installed, I formatted) (1 week old) I'm a designer- 3D, Graphic, Video/Animation, Web, Architecture: Relevant because that's how I use data, massive numbers of files, versioning, etc. Tons of very large files as well. What I'm trying to achieve: Create the fastest, safest, easiest to manage storage scheme. I'm guessing that RAID 0+1 is my best best. Question: Do I order the Mac Pro RAID card? Are there alternatives that are as good or better? Do I need new drives? I'm kicking myself for not having ordered the server grade drives but in the worst case I can turn these into externals. Considerations Based On My Use: 1. Transferring data between volumes is driving me insane. I find myself needing to reallocate the drives on a regular basis as space becomes scarce. The speed of the transfer is ok (SATA2, 300MB/s; I get about 50-60mb/s I estimate)but I would love for it to be faster. 2. This scenario presents a nightmare if an organization scheme is not followed exactly at all times. Because similar data has to be spread across volumes there is no reasonable way of maintaining order (aside from diligent use of Version Cue/Subversion or <ghasp> a pen and paper catalog; neither is human-proof). Anyone who's used illustrator a great deal can probably empathize on how awful it is to sift through (drawing1.ai, drawing2.ai, drawing3.ai, drawing4.ai, drawing5.ai .... drawing137.ai) This exponentially worse when you have multiple volumes to deal with. I don't like dedicating volumes to content because then when one fills up it's another problem of finding somewhere to move stuff. 3. Additionally, there's no nice way to use time machine or spotlight on this kind of setup. They just don't seem to like it and spotlight often hangs while indexing or just "forgets" certain locations. It also tends to find Font Suitcases and go nuts with them. Yes, I could private these folders, but again, that just impedes the organization functionality. RAID redundancy is attractive but mirroring would reduce me to less space than I want. Striping+Parity Checking sounds really great though! I could keep a carbon copy of the OS on an external just in case of a disaster where I couldn't boot. 4. WTF is wrong with spotlight. It breaks every Mac I've owned. I'm sure it's my files but .... wtf. The preferences are so lean and using mdutil is just as bad. Is there another brute force file finding tool that is better, more cohesive, than easyfind? Any help is very much appreciated. Thank you for reading!
