I am looking for ideas, personal experience, and advice on what other users are planning to do once they hit the 16TB limit. Without taking into account the recent issue WD had with its servers what are users doing with respect to the future of your “Personal Cloud”. Are you staying with WD, or looking elsewhere? I know for me personally I would say that with the current rate of data being put on my EX4 16TB unit I expect to hit the cap within the next 2-3 years (quicker if my 15 users take advantage of their free space I gave them in their share, but its unlikely they will). While 2-3 years leaves a lot of room for new breakthroughs by both WD and other companies along with changes in the firmware I was just looking for ideas since as of today if I were to invest in additional large scale(3TB+) USB devices to expand via the 2 ports on the device those share are public and thats a huge no no since my users cant have write access except for this own share folder.
Also, what is the rough time frame to move to a new device with respect to drive failures. I know with a laptop its every few years. How often do you move to new NAS devices?
