The Thecus W4000+ 4-Bay Windows Storage Server is a solidly built product that is well suited to handle the shared storage needs of a small office / home office environment. It does not have all the bells and whistles of plugins and apps available on other NAS servers, but it does run on Windows Storage Server 2012 R2. This interface may be preferred by users in corporate environments, although it may make it less appealing for personal use.
