I need a storage solution that needs speed and reliability. Even my internal HDD has a hard time keeping up with video files I produce. I have a 17" MBP and have started other threads in my search, but as I learn more questions develop. I've decided on eSATA and to get a eSATA express card (for greatest speed). But I don't have money for a fancy setup. RAID 5 looks like it would be ideal since I get the most storage for the price of the drives (i.e. 3x 1TB drives would give me 2TB whereas I would need 4 with RAID 0+1). But I haven't found a way to get RAID 5 with a MBP (or with any Mac for that matter, for some reason I can't find any info on how to even do RAID 5 or if it is or isn't possible with a MBP) or if this RAID setup is even affordable to me. The other affordable option for me that I've thought about is getting a dual eSata enclosure or dock (with 2x eSata ports) and set up 2 drives RAID 0. Then with another 'cheap' setup (USB2.0 even) I could schedule backups for the RAID 0 setup. That way the cheaper backup drive won't slow down the RAID system and I won't need a larger 0+1 setup. I know the cost of the drives are a given. It's the enclosures I feel I can do more affordable. A drive like this (or this if I was hotswappable craziness) I could stripe then just find the cheapest solution for the backup. Ideally I would like to not have to rewrite the entire backup every occurrence but only rewrite what has changed. Do you have recommendations as to software to do this? If this idea is garbage and no one has a suggestion for RAID 5 I think I'm just going to have to toss the stripping idea and just mirror.
