The Synology DS220j replaces a used 4-bay Buffalo LinkStation LS-QVL/E-AP. Slow, bulky and occasionally noisy, I never seemed to be able to get the Buffalo to work in my network properly. It was my first introduction to setting up a home NAS and an important one – software and GUI on the backend matters. In my research for a replacement NAS, it came down to either Synology or QNAP while considering ASUSTOR from time to time.
