I can second that, I don't have Arch installed on a 4k drive but I have an external drive, which I partitioned with fdisk -c -u /dev/sdX and there's no speed drop at all, so you can use this command line without any worries

Some of these 4K drives export their sectors to the OS as 512 byte sectors. If you happen to align your partition incorrectly then, every inode read/write will result in 2 sectors being touched. For drives that export their sectors as 4K units to the OS, there's not a single issue. Just be aware of this fact, I don't know how fdisk aligns stuff these days, but for my SSD I chose to use parted.
