A:Answer Hello there, and thank you for your interest! As this system uses a B660 motherboard, you should refer to your BaseBoard Manufacturer's website for all compatible HDD devices. However, we would recommend using M.2 NVMe SSDs, as they are the fastest form of storage at this time. There should be an extra 2 M.2 NVMe SSD slots on your motherboard that you can use for additional storage. Some of the brands we use for our SSDs are Western Digital, Samsung, PNY and ADATA for reference.
