November 6, 20232 yr I've been using Unraid for about a year and a half now. My use is nothing exotic, just as a backup destination for several computers on my local network. My array is currently 2 16 TB parity drives and 3 data drives (14, 14, 16). SATA interface. Parity check takes about 50 hours for that array. The speed is about 85 Mbytes/sec. Is that about what you would expect? Also, the array is about 75% full. Any guidance on how full it can get before it would be a good idea to add an additional data drive?

November 6, 20232 yr Author I've attached the diagnostics file, and the summary of the parity check that just completed. tower-diagnostics-20231106-0949.zip Edited November 6, 20232 yr by tomc
November 6, 20232 yr Community Expert Solution You are using a controller with a SATA port multiplier, and 4 of the disks are sharing the same SATA port, so bandwidth is affected a lot, see here:
November 6, 20232 yr Author Thanks. I will look into better interface options. What I have now works, but from that thread on recommended controllers it looks like it could be a lot faster. Tom
