I have two hard drives, both are 220MB/s write tested. However when copying huge files (no fragmentation) from one hard drive (external, usb3.2typeA on motherboard IO panel, 10Gb/s) to the other (internal, sata3, 6Gb/s) the speed is only around 110MB/s. I also noticed that in task manager, their usages are throttling between 30% to 70%, and an interesting fact is that despite throttling, the sum of their usages is always 100%. I suspect they're sharing some kind of bandwidth. Is there any way to let both hard drives reach 100% usage and 220MB/s speed?

Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking.– Community BotCommented Aug 13, 2022 at 19:14

If those are Hdd (spinning disks) , they typically use write buffers to speed up short writes. Once the buffer is full, you hit the real speed of the disk: 110MB/s sounds nominal for a consumer hdd. To get a better answer you'll need to provide the exact models of your disks.– 1NNCommented Aug 13, 2022 at 21:36

They are 220MB/s write tested, with content sized 2GB > cache. The models are WD Red Plus and HC550.– engise226Commented Aug 13, 2022 at 21:50
