raid 0 with 2 partitions

[Sebasboy]

hello. i've got a a macbook here running mojave on 2 samsung 850 evo 500gb in raid 0 for 1 tb of data.
i want to have 2 partitions (500gb/500gb) is it possible to do this with a raid?
i'm going to reformat the os anyways so i got the boot disc already here to redo the raid
i've tried partitioning it via the installer but the partition option is greyed out

Yes it can be done but must be from the command line and as I discovered when doing it three will not work for the number of partitions. Apple removed the raid option from the graphical installer a few releases ago. You will need to search for the command to do it, they are out there it was not that hard as I remember it, except the failing of the third I was trying to do. I still use the OS part of it for a backup now I have NVMe to boot from and the large data partition is use all the time.
