I would greatly appreciate assistance in choosing the best storage product for me. ** I own a iMac with a 2TB hard drive ** I am looking for more storage space plus backup ** I am presently using 3 external drives - 2TB Airport Time Capsule, 2TB WD drive and 1.5TB LaCie drive ** I do a Time Machine backup of only data files to the Time Capsule; a full backup of my internal hard drive to the other 2TB drive using a 3rd party program - this drive is bootable; the 1.5TB drive stores my videos, no backup done of these files ** I have about 1TB in music files and almost 1.5TB in video files ** There are 2 immediate issues - a) I will soon run out of space on my LaCie for video files and, b) the video files are not being backed up. ** A future issue to consider is I might sell my iMac with 2TB storage and use MacBook Air with much less storage space available internally. ** I would like 1 backup of every file, 2 backups of my music files which I consider invalulable and might as well kill myself if I lost them, haha. Any suggestions appreciated. I was pondering the My Cloud EX or an NAS, but I have no need to access the files from another computer or device. I like the idea of having RAID, not that I'm all that familiar with it. Thank you.
