I'm starting a new computer assembly, and this time I'm thinking of doing things different. Probably my main problem is that I use my computer for several things: personal matters, video files for home use and video editing. Both the second and third applications have particular demands. For video home HDDs have to be large, but I use them most of the time at night, to watch things. For video editing, HDDs have to be reasonably fast and probably this time I will use them in RAID. The problem is internal space, as I end up with at least 5 HDDs and the DVD to fill up all my SATA connectors, even if my present case (Antec P180) would need some arrangement to put them all inside. All this generates internal heat and probably stresses the supply, so I'm thinking of putting the home video files outside the case, and even going for 2.5" HDDs, housed in separate cases, USB 3 interfaced and powered through USB too. The latter is important. I believe poor external supplies have damaged some of the HDDs I used in the past, as they broke shortly after using them with such adapters. Housing the HDDs on an external box, holding 4 or 6 of them, might be an option. But those are quite expensive where I live (Rio de Janeiro, Brazil), and also seem to have not so reliable PS too. So those are the variables for my arrangement. Which path would you advise me on going through?
