Sorry if these questions have been asked / answered before, but I'm still deciding on what to do as a replacement for my current setup as well as trying to determine if I can reuse the current drives I have. My current Synology NAS has four WD Red 3TB drives, is around 4 years old, has been trouble free thus far, but we're running out of space. It's mainly used for media storage, photos and time machine backups. Our photos are also stored on Amazon. I'm hoping that I can set up a unRAID application server to take advantage of the various functions with an array of three to four 4TB drives, migrate the data and then add the four 3TB drives from the Synology to the array, after formatting / clearing them. Based on what I've read thus far, this seems to be a possible migration path; however, since the drives are approximately 4 years old, I'm curious as to the community's thoughts on reusing these older drives or should I just starting with six 4TB drives and call it a day. Is it possible to create a second array with these older drives and use them for less important data?
Thanks in advance for your help...
