If you're only storing a few Terabytes of data, I'd buy a 2-bay NAS and two 8TB disks -- or wait awhile and buy two 10TB disks. Depending on your workload, you could even buy two 8TB external drives, hook one up to your router and periodically sync it's contents to the other drive kept in cold storage.

It's useful if you want to rip multiple discs in a row and not babysit the process. The issue would be minor if you have a fast drive and all discs rip consistently quick, but that's usually not the case. Some people are stuck with slow external/laptop drives, some discs have mastering errors/damage, some discs are SL while others are DL, and sometimes the drive just rips at half speed because... who knows why. A notification system can save a lot of time and mental accounting. Put disc in, start rip, do something else, disc pops out, "Oh, rip's done," put new disc in, start rip... ad infinitum. If you aren't interested then no problem. It's just an idea I thought might be useful.

Would it be possible to add auto-eject via a BASH script or similar? It's one of those MakeMKV requests that has been on the back-burner for years.

Dual channel helps parity checks on server with many disks (12+), if I’m remembering correctly got an increase of about 10 to 15% on an Intel server and a little more on AMD. Do you think it depends on disk number or total bandwidth? In other words, would 1x 8TB drive see the same benefit as 2x 4TB drives? Dual channel seem like it would help my anemic CPU deal with the I/O of parity operations, but you're the first evidence I've seen. If you remember from the other thread, I'm the guy hoping to jam 16TB drives into an N40L.

i would be surprised if that was enough RAM for cache-dirs to be effective with that number of files. Yeah, I haven't seen conclusive evidence either way. My understanding is that it was a bigger deal when UnRAID was 32-bit and cache_dirs had to stay in the low_mem split. I've seen an estimate on this forum that each file entry probably takes no more than 256 bytes of memory or ~250MB per million files, which should comfortably fit now that cache_dirs has access to the entire system memory. Dynamix File Integrity Plugin is still a major question mark for me. Other than CPU load, I haven't seen anyone mention resource usage. This is slightly off topic, but I've also never seen evidence whether dual channel memory actually makes a difference in UnRAID or any of its plugins.

How much memory does this plugin use? I'm trying to estimate my memory requirements on a new build so I don't overbuy. Would 2GB be sufficient if the only other plug-ins used are system utilities and cache_dirs? Does the memory requirement grow with array size? If so, then how much for ~75TB and ~1 million files.
