There is no problem with having home on a different disk. But why do you want swap on the slower disk? These would benefit from being on the faster disks. Same with all the system binaries.
Personally I would put as much as possible on the faster disk and mount the slower somewhere that the speed matters less. Like for photos/videos in your home dir.
/boot can be anywhere though if you are getting a grub error that suggests the UEFI firmware is finding grubs first stage but grub is having issues after that. Personally I don’t use grub anymore, systemd-boot is far simpler as it does not need to deal with legacy MBR booting.
