Thanks for the info. I can't do it with any. Mike.

Hi thanks, I am clicking everywhere yet I get no offline option. I am using W10 Home, not pro or other. Maybe that's an issue ? Mike.

Hello, If I remember correctly in older operating systems, right clicking on a disk in disk management gave the option to offline/online a disk. It doesn't seem to be there in W10. Is there a simple way of doing this for a disk connected by sata. Also would it switch off the power to the disk to stop it spinning, then back on again. Grateful for any advice. Many thanks. Mike.

Thanks SavageNeo, Radium_Angel & Mira Yurizaki for the replies. I think you've confirmed what I suspected, that being it will have to run as it is. I thought I would look into it now instead of finding out later it could have run at a higher level all along. Regards, thanks again. Mike.

Hello, Any advice on this would greatly appreciated. I have read up on this matter as much as I can but my abilities with computers are limited to be honest. I have a small MSI PC on which the Motherboard has one M.2 slot. It came with a M.2 Sata drive which I changed for a M.2 NVMe successfully. The M.2 NVMe drive claims a max speed of over 3000mbs. With CrystalDiskMark my max speed was around 1700mbs on the top line for Read, therefore around half the claimed max speed for this NVMe. With CrystalDiskInfo in the transfer mode section it states - PCIe 2.0 x4 (as current mode) PCIe 3.0 x4 (as supported mode) NVM Express 1.3 It was mentioned to me that PCIe 2.0 x4 might be the problem causing the NVMe to not achieve its max speed and that I should change this to run on PCIe 3.0 x4 I cannot see anything in BIOS for that. I have read something about the M.2 NVMe being put in to an adaptor and placed in a PCIe slot instead of the M.2 slot. I'm sure this PC has just one PCIe and that has the graphics card in it. The PC is very small and wouldn't take anything else inside anyway. The motherboard has MSI B9181 on it, which I can't find much about. I suppose I am asking that if CrsytalDiskInfo states PCIe 3.0 x4 is supported - will this board run the NMVe up to much higher than 1700mbs. Also, how would I do that ie. make PCIe 3.0 x4 the "current mode" instead of PCIe 2.0 x4 ? Will it not do so with the NVMe drive in the M.2 slot ? Many thanks. Mike.
