I couldn't see any mention of M.2 or SATA ports being disabled for whatever reason, in the manual. Any ideas?


Mobo: ASUS Strix Z370-I w/ latest BIOS
CPU: i7-8700k
Storage: 2x Crucial MX300 2TB SATA 2.5 (RAID1 - for file storage)


I can't get any combination of the following to work in the two M.2 slots. Was hoping to have one run Windows 10, and one for a gaming/recording/scratch drive.

1x Crucial MX300 2280SS 1050GB M.2 SATA
1x SAMSUNG 960 PRO M.2 1TB NVMe
1x SAMSUNG 960 PRO M.2 512GB NVMe

I've only managed to have the 512gb detected in the second M.2 slot, when the first M.2 was empty. The two 1TB are only detected in the first M.2 slot; which may just have been due to BIOS settings. Accidentally installed win10 on the 512gb with the incorrect BIOS settings (RAID1 2.5" SSDs not set up beforehand), so I just set those up and then reinstalled win10 on the 1TB crucial M.2 ssd instead.

Seem to have fixed it.

Booted with an M.2 in the second slot and everything else disconnected, using win10 usb. Exited at the drive selection page after entering Win10 serial key; shut down and then reconnected the 1TB with OS installed back into the first M.2 slot. Logged in, reset, logged in again and it showed up in disc management. Formatted it, reset & plugged the 2.5" raid drives, logged in, reset, logged in again - working fine now.

Weird how it took 2 logins and a reset in order to detect the changes. I shut down, replaced the 1tb nvme with the 512 nvme in the second M.2, and when I logged in, the 512gb ssd was listed as being 1tb, until resetting.

Why oh why use raid at all? IT IS NOT A BACKUP, if you are going to do this then have 2 drives, and backup from one to the other.

Raid1 will give you uptime and security from a disk going bad, that's all. You delete a file accidentally, raid1 doesn't help, file gets corrupted, raid1 doesn't help, malware, raid1 doesn't help, cryptoware, raid1 doesn't help. You can reduce the total cost because the backup doesn't need to be fast, put it on a NAS, put it on cheap spinning disks, whatever, but raid1 unless you need 100% uptime and cannot cope with an outage of a couple of hours every 4-5 years whilst you restore from a backup is not the solution you think it is as it will do nothing for you.
