I rewatch things all the time. If I’m doing side work at night and just want something on the background I’ll put on a movie or show that I’ve seen before. Beyond that, hard drives are cheap! I have a single 18 TB disk in my main computer that runs Plex. It lets me and my kids watch content from anywhere with an Internet connection. 18 TB hard drives are about $300.

A single terabyte can hold at least 500 hours of 1080p video. A few terabytes is plenty to keep a large library of rewatchable content AND download new stuff frequently (and delete it when you need room)

After 4tb dlof data I started to get weirded out by running too big disks. Resilvering might take ages. So long that raid2 might be mandatory. I haven't calculated the right risk factor but I still only use 4tb disks

  Eh I recently switched to two 14tb disks of different manufacturers. One is usually in standby and once a week I do a rsync to it. Btrfs on both for checksums. Good enough for me, I assume it's way more likely that a PSU failure fries them all, in which case no variant of raid would have helped anyways. For important stuff I have an off-site Backup, but that's only around 800gb anyways and growing a few gb per year.

  A rebuild of a 160tb raid 6 array of 12 18tb disks for me takes around 3.3 days.

> Beyond that, hard drives are cheap! I have a single 18 TB disk Fair warning: It is very dangerous to make statements like this in a public forum like this. You run the risk of someone spotting it and making a seemingly-innocent reply along the lines of, "Oh, you should at LEAST have TWO disks set up as a mirror so you don't lose all your movies when (not if, but when) the disk dies." And then someone else will say, "LOL u noob, RAID not a backup!" Another participant will assure you that no data is safe unless it's stored at on at least a 5-disk ZFS array. And then someone else will jump in to point out that even ZFS is not safe if you're not running ECC memory. And course you can't just have ONE of these ECC-enabled 5-disk ZFS-breathing monsters, because every component ASIDE from the disks is a single point of failure, so you'd better have TWO just to be safe. Which means you'll need a UPS because sudden power loses are _awesome_ if you like having your platters scribbled all over by a browned-out disk controller. And what exactly is your disaster recovery plan in the event of a fire or flood, gotta have some infra running in good health off-site in case something like that happens. And so on. Of course if you dig far enough into these admonitions and suggestions, the good news is that you won't have the time to watch any of those movies.

  My only fear is that your absolutely fantastic comment is too far down the tree to get the attention it deserves.

  Thank god I have an ECC memory stick and a mirrored/striped 4-disk ZFS array. Weight off my shoulders!
