I assume your talking about NVMe's
why would you want to run m.2 in r1 and end up sacrificing 4 sata ports?
Each NVMe you add onto that board will disable 2 sata ports.
So if your board has 6 total, you just lost 4 out of the 6.
Unless you really have nothing better to add to those sata ports.
Hmm. I have an AMD Threadripper cpu/board. With 60 pcie lanes I thought that wasn't going to be an issue. I don't see anything in the MB manual that states the SATA ports will be disabled.
Yes I know RAID-1 is mirroring. I like redundancy in my os. I don't want to turn my computer on one morning to finish a project and have it not boot to the os because the drive died. But with today's drives I assume these new ssd drives are more reliable and don't need to worry as much. As long as you keep a live backup of the os drive.I think you may be confusing RAID-0 for RAID-1. The former doubles space and in some metrics performance but you are better off just getting the next size up in drives. RAID-1 is mirroring and normally does nothing for performance (some controllers can read from both drives but write speed is always equal to one drive). There really is no point for RAID-1 unless it is used in a tiered storage volume or a system that cannot be offline awaiting replacement and reimaging of the failed drives.
Oh, gotcha sorry about that! I would run RAID-1 with SATA but with NVME, just a single should be fine. For whatever reason, even though they run hotter and draw more power, premature failure is exceedingly rare with them. Though since it can happen, running mirrored may still be worth it for your use! Beware of the SATA ports being disabled as aigomorla pointed out.Yes I know RAID-1 is mirroring. I like redundancy in my os.

I ended up just getting a 500gb for OS and 1TB for data. All data ports on my Taichi X399 still function. Since threadripper has enough pci-e lanes nothing is disabled. I can still add a third NVMe drive. Drives work fast and speed test shows 450-500MB/s write times. I can copy a 5GB file to them in a couple seconds. Lol.Oh, gotcha sorry about that!
