Anyone here with a NAS at home? I've had mine since 2012 or so, a Synology DS411j with 4x3tb drives in it. It has served me well, the hard drives are still in good shape, according to the SMART tests, but they have over 25k hours of usages. Which is a lot! I'm dreading having to replace them

The world of OS and apps available for this kind of product has greatly changed since, now you can run PLEX, torrent clients, vpn clients and stuff. My old NAS only has 128mb of ram in it, so it's kinda hard on it. This does not accept file transfers speed/ hard drive access, it's only slow for all those cool new apps.
Still, I bought myself an external bluray drive, and i'm going to start dumping all my bluray to the NAS. I only have 3TB left on it, and considering I have about 250 blurays. Back when I first got the NAS, I had a started a similar process with my dvds, but it turned out to be a lot of work, and frankly, my old self made dvd rips are kinda crap to look at. I mean; they're alright but they all look like netflix movies.
So basically I'm going to start dumping my blurays to mkv and don't do any kind of compression. I want my shit to be future proof. These days, they have NAS with hardware transcoding.. I might just get one, and use it to store the movies. The other stuff is gonna go on the old one. It's kind a pretty damn expensive investment to make

, I'm aiming for a 4 bays one with perhaps 6tb drives. we'll see
I also got one of those Western Digital Ultra Passport the other day, the 4TB model. I remember when usb drives started, my first drive being 32MB

I bought it to make a backup of the most important data on the NAS, I mean, it's on raid5 and everything, but like I said, the drives are getting old so it wont hurt to have an external backup.
So what do you guys have?
