Summary: I bought this unit from NCIX on sale in December 2012. Since then, I have had several problems with this product, most notably two major meltdowns that resulted in significant data loss. After about 6 months of use, the unit stopped working. Qnap support was able to remotely diagnose, reconfigure and restore device operation, but the data was lost. There was no explanation, except that this can occasionally happen.
Pros: Cost, features, size.
Cons: Unreliable, limited hard drive compatibility, apps often do not work, dis-assembly required to install drives, print server occasionally stops working.
