Hello,
I'm am just getting started using unRaid and have some questions about the Cache drive. I was reading through the Wiki pages when I came across this last paragraph, which kind of spooked me: '
Amount of data
The final consideration in choosing a cache drive is to think about the amount of data you expect to pass through it. If you write ~10 GBs per day, then any drive 10 GB or larger will do (a 30 GB SSD may be a good fit in this case). If you write 100 GB in one day every few weeks, then you will want a cache drive that is larger than 100 GB. If you attempt a data transfer that is larger than the size of your cache drive, the transfer will fail.
I know this is a little outdated, but my concern it that I will be going from a video server that runs and stores my Plex media (1 to 1 BluRay rips) to a new tower running unRaid. My library is running a little over 5TB in size and my concern is that if I try to copy all of that over and it's larger than the cache drive, will the copy fail and possibly lose what I'm copying over or will it just copy to the data pool and by-pass the cache drive? Thanks for any help. I'm sure I'll have plenty more questions.
