Only 3.5in drives are supported, so don't contemplate adding high-speed 2.5in SSDs, and "in order to provide the highest reliability to customers" the Sentinel DX4000 has a rather short list of compatible hard drives. The process of chopping and changing drives couldn't be easier - you'll never be left searching for the screwdriver - but there are a couple of caveats. We're often pleased by the simplest things, so it's no surprise that we're fond of the tool-free drive bays simply open the bay covers and the drives slide out on metal rails.
#WESTERN DIGITAL WD SENTINEL DX4000 PLEX SOFTWARE#
The software will feel familiar to users of Windows machines, and of course integration of Microsoft services such as Windows Domain and Active Directory should prove to be straightforward. Unlike the vast array of Linux-powered alternatives, Western Digital's decision to opt for a Windows-based environment makes the DX4000 an obvious fit for many small-office businesses. Speaking of software, one of the DX4000's primary draws is that it runs Windows Storage Server 2008 R2 Essentials and supports up to 25 clients.
Cooling, meanwhile, is provided by a 92mm fan that, while boisterous and noisy during the initial setup phase, is controlled through software and quietens down to an acceptable level during everyday use. WD includes two external power supplies as part of the 16TB bundle, giving users an out-of-the-box backup should one fail. A mesh front door is easily opened to reveal access to the unit's four spring-loaded, hot-swappable drive bays, and just above that a two-line LCD display provides at-a-glance status information that can prove helpful during setup.Īround the back, the Sentinel DX4000 carries dual Gigabit Ethernet ports with fallover support (but not link aggregation, surprisingly), two USB 3.0 ports for attaching additional storage, and a pair power connectors. This is the same DX4000 chassis that's been doing the rounds since late 2011, but that's no bad thing WD's 206mm x 224mm x 160mm enclosure remains well built and has a real quality feel about it.
