August 26, 20241 yr Hello - I recently updated my CPU/MB/RAM/GPU when my son built himself a new PC. Unfortunately I don't have the old specs, but the new specs are: MB: ASUSTeK COMPUTER INC. - PRIME B550M-A RAM: 32GB (4x8GB) DDR4 CPU: AMD Ryzen 5 2600 Six-Core Processor GPU: NVIDIA GeForce RTX 3060 None of the drives have changed (I replaced a bad cache drive since the HW upgrade, but nothing has changed with the speed of the parity check. The drives are a single 6TB parity drive, and 4 drives in the array (2x 6TB and 2x 4TB = 20TB) with a 500GB SSD Cache drive. Currently the parity check is running at <60 MB/sec, and will take ~30 hours at the current pace. Before the HW change, it would run ~110 MB/sec and finish 14-15 hours.

Any advice greatly appreciated. tower-diagnostics-20240826-1508.zip
August 26, 20241 yr Community Expert Solution You have a controller with a SATA port multiplier, and it's using the same port for all connected disks, since there's an extra board port, connect one disk there and try connecting the other two to to different main ports.
August 26, 20241 yr Author Unfortunately the board only has 4 SATA ports, so I will move 1 to the open port (I had an unused cable I removed and didn't think to move one from controller). Is it better to have specific drives connected directly to the board vs. not?
September 1, 20241 yr Author This worked wonders....2 completed checks since moving 1 SATA cable directly to the board have been more than 2x quicker. Thank you so much @JorgeB.
