Until now my data backup efforts have just been using a 1TB external HDD to back up my PC's HDD, which is also 1TB. I also have a 256GB SSD which is not backed up, as SSDs are invincible amirite? PC's HDD is now pretty old, since 2011 I think. My HDD data is a mixture of videos, photos and music. SSD content is just programs and games. So it's about time I upgraded my backup approach to this decade, and seems like a NAS is a good way to do this. The benefits of being able to have access to all my files on the go, and also stream directly to Plex on my TV would be nice too. Wife's mac hasn't had a backup in a while either. My initial thoughts are a 2 bay NAS with 2TB in each bay, which gives me room for all of my current data plus more, and ability to have a RAID setup for extra performance and failure proofing. Regarding plex and video streaming, I keep reading about transcoding and hardware acceleration, but still can't work out if I need it. I never had any problems using direct play with my plex server just set up on my PC's hard drive and playing directly from there. So would I be OK with basically any remotely up to date NAS? Or do I need to worry about being able to video transcode? e.g. the Synology DS218Play chipset won't work with plex directly I don't think, whereas the DS218+ can. But is that just a transcoding thing and do I need to worry about it?
