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.
