Western Digital Sentinel DX4200 review
It’s good value but WD’s Sentinel DX4200 fails to impress as a backup appliance

SMBs that want a storage appliance that'll slip easily into their Windows network might find WD's Sentinel DX4200 fits the bill nicely. The brain behind this 4-bay desktop box comes courtesy of Windows Storage Server 2012 R2 (WSS) so anyone familiar with Microsoft's standard server OSes will feel right at home.
It's a significant upgrade over the Sentinel DX4000 which still chugs along with Windows Storage Server 2008 Essentials R2 at the helm. The DX4200 has a more useable 4GB of server-grade DDR3 and although its dual-core 1.7GHz Atom C2338 CPU doesn't offer much of a speed boost, it does support up to 16GB of memory.
You can't buy a diskless appliance as WD only offers it in 8TB or 16TB capacities. We have the latter on review which came with four 4TB WD Se SATA hard disks included.
Another smart feature is the OS is installed on a 500GB SFF SATA drive tucked away in the side of the chassis. You can also fit an identical SFF drive in the carrier on the other side for a fault tolerant mirror.
