No internal PCIe slot The TS-464 lacks a PCIe slot, so you cannot install add-on cards like a 10GbE adapter or NVMe cache inside the unit.

USB-only expansion You get two USB 3.2 Gen 2 Type-A ports and one Type-C port, but these are your only way to connect external storage beyond the four drive bays.
