Hi all! I'm looking to get a RAID storage for my Time Machine Backup and/or Basic Storage. I was close to purchasing 4.0TB OWC Mercury Elite Pro Qx2, but I began having second thoughts. Is a RAID storage worth getting if I plan on using it for Time Machine backups? or am I better off with NAS? I did try a NAS for a bit (a DiskStation 411j with x2 1.0TB Western Digital Green Caviar HDD - WD10EADS), but it was extremely slow accessing it and creating my time machine backup. It said it would take at least a month to complete a full backup. The NAS was also connected to directly to my AirPort Extreme. I do like the versatility of a NAS, but it seems like I'm having a hassle setting it up already. Therefore, I forgo this solution. However, I did see people having plenty success with it. Maybe I have a slow performing Hard Drive installed. Should I give it a second chance? So, I thought it would be great to open this topic here to get some feedback based on my situation. Any thoughts? Thanks all!
