Hello!
Please help me understand the strange behavior of the hard disk when working through the H240 controller. I have two SATA 4TB hard drives: HGST HUS726T4TALE6L4 and Toshiba HDWQ140UZSVA. Both are connected to the H240 controller and configured as RAID 0 volumes, consisting of one disk. The first one always works at maximum speed (about 200 MB / s). The second reads at maximum speed, but writes at about 75 MB / s. At the same time, if you connect it directly to the motherboard, then it writes at its normal speed of about 200 MB / s. Why it happens? Is this some kind of controller incompatibility with the HGST drive?
I have swapped the SATA connectors, but the speed of the HGST drive is still slow. I've deleted volumes and recreated them to no avail. Please, help!
My controller's firmware version is 7.00 and driver version is 8.0.4.0. Current Power Mode is "Max Performance", controller temperature is 86┬░C.
Solved! Go to Solution.

SolutionI ran some more tests, and it turned out that the problem is not in the hard disk, and not in the controller. The problem is in bugged Windows 10, which in some situations cuts the speed when copying. I have installed Hyper-V 2012 R2 on a test machine and all my disks in the controller are writing at maximum speed. The question is closed.
