The Dell OptiPlex 7070 SFF fits three drives for up to 6 TB

For a small form factor machine, the 7070 SFF packs surprising storage flexibility. An M.2 slot handles up to 2 TB NVMe, and two 2.5-inch SATA bays each accept another 2 TB. That’s three drives and up to 6 TB total in a chassis that barely takes up desk space.
