I have a very high end system. It includes an i9 9900k, maximus xi extreme, 32GB corsair ddr4 3200. The drives are 2x10tb IronWolf Pro drives.
If I transfer from my SSD (Samsung 970pro) to one of these drives while someone is watching a movie then it will pause almost completely. IT will unpause occasion for a second here and there.
If I transfer a 4k movie file between them then the movie playing on my appletv will pause or halt again.
I added in 2x 10tb Barracuda Pro’s. If I transfer files between any of the 5 drives the movie will halt. Even if the movie is playing from a completely seperate drives to ones with the files being transferred.
This is driving me nuts. The only thing I can think of is those transfers run at 100% utilization.
I expected more from these components.
Anyone else experience something similar.
Your copy operation is monopolizing the available bandwidth of the hard drive, since your ssd can deliver the data even faster than the mechanical drive can write them. A you need to remember that the read/write head of a classical hard drive can only be at one position at a time. So if it has to both read a file for plex and write a file due to your copy process, it will probably halt the ‘read’ operation since the write process has a higher priority.
There are no good solutions.
Some ppl recommend to use robocopy instead of the normal copy (but that is a command line tool).
You could try to set the computer to behave as “server” (which will prioritize “background” tasks more than “foreground” actions).
Or simply wait with large file (larger than ~50% of your RAM) operations until Plex is idle.
I figured. I just wish that the system would split the resources. These drives can do 250mb r/w and a 4k movie only use 11mb to play. It would be nice if the file moving process dropped to 80% or something rather than running full bore.
Thanks for taking the time to reply!
