3 Things to Know About the QNAP TS-233’s Lack of Expansion

No PCIe slots Regarding the QNAP: The TS-233 has no PCIe slots, so you cannot add any expansion cards like a 10GbE network card or a graphics card.

No external drive bay support You cannot connect external drive bays to this NAS. The two internal bays are the only storage you will ever have.

Limited upgrade path Without PCIe slots, the TS-233 is a fixed configuration. If you need more storage or faster networking later, you must buy a different NAS.
