3 Things to Know About the Lenovo ThinkCentre M70q Gen 3 M.2 Slots
Regarding the Lenovo ThinkCentre: 1. The M70q Gen 3 has two M.2 slots, but only one is for storage. The 2280 slot supports NVMe drives. The 2230 slot is reserved exclusively for the wireless card.
Do not assume the second M.2 slot can hold another SSD. It is physically sized for a 2230 module and wired only for Wi-Fi or Bluetooth cards.
If you need more storage, use the 2.5-inch SATA bay instead. The system includes one internal SATA slot for a traditional hard drive or SSD.
