I bought one of these Topton trash cans a while ago (or whatever the real manufacturer is). It's the cheaper Intel N100 version. I'm running Windows because I really need Windows software and drivers on it (e.g. decent HDR on display out when using MPV), but the Raid 1 performance is... awful. Locally I get maximum 100 MB/s write, over network when using fastcopy or unencrypted FTP I top out at 75 MB/s (the network is 2.5 GB/s and iperf checks out, although the other devices sadly top out at 1 GB/s). The drives themselves are two identical 7200rpm 18TB Seagates, CrystalDiskMark performance checks out.

Is it just N100 being too weak, or is it specifically Windows being _this_ bad? I don't really want to format the NTFS Raid drive again just to test it on Linux/TrueNAS/whatever because I kinda already copied a ton of data there.
