Thanks for the info. I wasn't aware of needing to pre-clear first. Anyway I've done that now and the graph looks the same as the Parity drive, so all good.

Hi I just built my first Unraid box and installed this DiskSpeed Docker container to test out the 3 new drives i purchased and installed. I did my first test of each drive and the results are below. From other images ive seen in this forum, the parity drive looks to be about right in regards to speed and the slow drop off in speed. Disk1/DIsk2 however look quite different and im just wondering if that's normal? The 3 drives are all WD Red 4TB (WD40EFAX) The parity drive is plugged into a SATA 6.0Gb/s port Disk1/Disk 2 are plugged into SATA 3.0Gb/s ports The motherboard is an Asus H81M-E Also when i complete the test on Disk1/Disk2 the following note is displayed "Bandwidth was capped on drive Disk 1 (sdd)" So does it look like there is an issue with the drives or am i doing something wrong? Thanks for any help.
