I currently have a Qnap 410, two of the drives needed replacing so I have just invested in 4 x 2gb drives... ..during the process of copying the files and replacing the drives my 410 has become pretty temperamental, & I think it has reached the end of its life.. I found the qnap pretty high maintenance and wanted something with more plug and play functionality...I was looking at synology, but I understand they have had some recent malware problems with users having their data encrypted and held to ransom. My ideal solution would be 3 2xtb drives in raid 1 (mirrored, and maybe a spare) It need to be accessible on my local network (I do not want it to be accessible from outs tide my local network)..but I would do a raid 5 and hot spare if needed. I will back up anther copy monthly and keep off site...its mostly just photo's but they have a high sentimental value to me, so I want to ensure there is a lot of redundancy. Any suggestions?
