[M] Synology DiskStation DS112+ High-Performance 1-bay All-in-1 NAS Server Review
 

The DS112+ from Synology is a full feature-packed NAS like the more expensive versions but does offer only a single bay, meaning that is more suitable for businesses that do not need a huge amount of storage space. However, thanks to the connectivity options (1x eSATA and 2x USB 3.0), we can attach more external storage to it, if needed. The read-write performances of the NAS are good, but these are always influenced by the installed HDD.
