Excerpt: QNap's TS-201 is the cheapest device here to provide easily removable disk trays. It has only two trays, though, and the preinstalled disks are secured by several screws that are difficult to remove. You can configure the disks as a RAID 0 or 1 array. The web-configuration pages are easy to access through UPnP but they're confusingly laid out. You can use the TS-201 to share photos. While it preserves and displays EXIF data, creating albums is tricky.
