The nasne with 2TB of storage is a high-performance peripheral for the PS4. - Brand: BUFFALO - Model Name: nasne NS-N100 - Storage Capacity: 2TB Thank you for viewing. I purchased this item new and unused from Amazon about 3 years ago and have been using it, but I am listing it because I purchased another product. My house has a TV and a router that are far apart, making a wired connection impossible. Therefore, I purchased a wireless LAN adapter separately and used it with a wireless connection (also purchased new on Amazon). Therefore, this is a set with the BUFFALO WLI-UTX-AG300. - The B-CAS card is inserted into the main unit. - Instruction manual and warranty are not included. - The TV cable is also not included, so please purchase it separately. There were no particular problems, and I was using it comfortably. Operation has been confirmed. Separate sales are possible, but I would like you to purchase it as a set if possible. Thank you very much. (*^^*)
