The ASUS UN65H supports two drives — one M.2 and one 2.5-inch

The UN65H gives you a choice. There’s an M.2 slot (SATA-only, 2280 form factor) alongside a 2.5-inch SATA III bay that accepts both HDDs and SSDs up to 7mm thick. It’s not the fastest NVMe setup, but the flexibility of having two physical drives in a mini PC this small is handy.
