Synology DiskStation DS220j, 2-bay NAS. Tested and working.
Sold diskless with no power adapter. You'll need a 12V 5A power adapter, about $15 to $20 on Amazon. Check the label on the back to confirm the rating before you buy one.
Specs: Realtek RTD1296 quad-core 1.4 GHz processor, 512 MB DDR4 RAM, 1 gigabit Ethernet, 2 USB 3.0 ports. Holds two 3.5" or 2.5" SATA drives and supports RAID 1 mirroring.
Software: it's supported by current DSM 7 and still gets updates from Synology. That means you can run Synology Photos, Drive, Hyper Backup, Active Backup and the rest of the current apps.
No drives are included. DSM lives on the drives, so it will set up fresh when you add yours. Ships within [1 to 2] business days. Feel free to ask any questions.
