A few questions about RAIDs in a Mac Pro tower: I am interested in using the Mac Pro RAID card to stripe three internal 1TB SATA drives in a RAID 5 configuration. Has anyone done this and used it for HD video playback? I know RAID 0 provides the best performance but I would like the protection from disk failure and I'm wondering if RAID 5 is fast enough to use for editing purposes in Final Cut. Also, does anyone know how much actual storage would be available from the 3TB after the RAID 5 was configured? Last question - although I know it's not recommended, has anyone ever striped all four drive bays together and run the Mac OS from the RAID? I'm thinking four 1TB drives striped together in a RAID 5 configuration would provide the maximum storage and maximum protection possible in a single tower. But obviously if there's a potential for major problems with this setup then it's not worth it. Just curious if anyone has done it and what their experience has been. Thanks!
If you stripe 3 of your internal drives under RAID 5, say if you have 1TB each. Instead of getting 3 TB, you will end up something close to 2 TB for you to use .
Using 3 regular sata drives under RAID 5 will let you edit 4 streams of ProRes HQ according to apple's site. I think if you want to do 10 bit uncompressed HD, you will need to use 4 drives which like you said it's not recommended.
Caldigit has a similar products call caldigit raid card which they claims to have external ports to connect more drives(more speed?). Maybe you can call them up or check out their website. http://www.caldigit.com
Thanks for the helpful feedback. Not only were my suspicions confirmed but the CalDigit RAID Card is a great tip. I was only looking at the Mac RAID card and HighPoint RocketRAID. I'll wait until the CalDigit card ships in June before reconfiguring my current - and woefully small - Huge RAID array. Thanks again!
