Synology DiskStation DS220+ 2 Bay NAS 10GB RAM and 2x4TB HDs
Upgraded from the base model with 8GB of additional RAM (10GB Total)
Includes two 4TB HGST hard drives. These are the Coolspin model that I think are 5400 RPM. I think I used these hard drives for about 3 years in my desktop.
The reason I'm selling this is that I bought a replacement Synology with more drive bays.
This is a good started NAS. It can replace many of the services from Google (Google Drive, Google Photos). It can backup your computers. It has the ability to run many applications provided by Synology and should be supported by Synology for several more years.
