A NAS allows up to 4 * 4 TB, with the legendary Synology utilities that ask for? Installation is very simple, perfect safety since a hard disk can fail without damage and finally has everything at hand without a fight with the waltz hard drives! Without obviously depend internet access to its data. Only downside: the slow generation of thumbnails of your photos, but after all, we do it only once. NB: My choice was not economic, son, student in computer science, has the model 411 (for 3 years so) that rotates like a clock! one of the 4 discs that dropped last year, I have seen firsthand the system's security: replaced with a new, repair request at night and in the morning, all the green lights without loss of data!
