This is a well cared for WD MyCloud EX2 NAS with 2 bays for 3.5in hard drives with the original power supply. The NAS allows for apps to be downloaded and run, such as Twonky for video and media serving, Transmission for downloads, etc. If you have a Mac, it can even work as a network Time Machine drive. I'm including a couple of Seagate 2TB hard drives and have reset the unit to factory-defaults.
Everything works great - if you run Mac or Linux, or anything other than Windows 11! With the security changes in how Windows 11 handles SMB/Samba, Win11 will not work with this NAS. For those not using Windows 11, this is a great little NAS. But users exclusively on Windows 11 will need to find something else.
The NAS includes one 10/100/1000 LAN port, and 2 USB 3.0 ports for adding additional drives, setting network-shared printers, etc.
