Synology DiskStation DS220+ 2 Bay NAS (Network Attached Storage) - DS220. 8GB RAM Upgrade, Has a total of 10GB's of RAM. 2x 5TB Hard Drives. Total of 10TB Striped Raid Storage or 5TB / Mirrored. Has ran flawlessly for me this past year, I really love Synology, the OS and the Apps and speed are really great! I have used it for a PLEX Server, SMB Shares, Apache, MySQL, PHP Server for my software development hobby. The only reason I am selling this is because it's time for an upgrade. This is a really nice trouble free NaS System.
