What channel partners are saying
“I love this little black box. The form factor is great, and the redundant NICs and PSUs go a long way to alleviating my issues with proprietary components I can’t easily replace myself.”Sam WoodDirector, Tentacle Software Limited
“WD Sentinel has been PERFECT for storing raw video footage and for storing all the client backups. I love it. I use it for 2 things. It is domain joined and backs up most of our workstations, and will be backing up a new Windows MultiPoint Server… I also use it as a secondary storage point for archived video footage.Dana EppCEO, Scorpion Software
“The size, tool less ease of service, and the dual/redundant power supplies and network connections make this a real work horse for a small office storage server. The LCD screen is also very handy to check the status of the unit. It’s been running great for me."Kevin RoyaltyManaging Partner, Total Care Computing Consulting, LLC

Most businesses—whether organically or by design—expand to multiple workgroups and branch offices as the organization grows and evolves. It’s a challenge for these different groups and offices to access and share data, and choosing the right storage solution without adversely impacting the entire company can be a daunting and confusing decision.
Traditionally, the task of managing data across workgroups and remote offices has been the domain of large corporations. However, companies of all sizes benefit from utilizing workgroups focused on common business goals. And forward-thinking companies are keen to take advantage of the opportunities provided by branches located closer to bedroom communities and pools of talented people.
The explosion of data, the dramatic rise in file sizes, and the need to access data from anywhere at any time via mobile devices create five unique trends for managing data storage for workgroups and branch offices.
