Western Digital is offering up a new line of network storage servers this week for small-to-medium businesses, with the Sentinel DX4000 being the star of the show. The device includes Windows Storage Server 2008 R2 Essentials along with Intel's D525 dual-core Atom CPU. It's designed as a centralized shared storage and automatic server-based backup solution for up to 25 devices (PC and Mac) on the network.

The device ships with capacities of 4TB and 8TB, and it also acts as the on-premise cloud storage for the SMB. The unit ships preconfigured with enterprise-class drives, RAID storage protection, built-in server based backup and recovery software, redundant networking ports and redundant power option. It also offers the ability to connect to a "public cloud" storage provider, and as far as software, WD throws in applications that will allow you to remotely access files and share files with external employees, independent consultants and satellite offices elsewhere in the world.

Pricing, as expected, is tailored for businesses. The 4TB unit is $949.99, while the 8TB unit is $1,449.99.

Good for small businesses. For larger organizations 8TB is not enough...

Cool... I can see this being bought by smaller businesses and some people looking for a very capable home server. Besides, that thing looks cool; and combined with WD's known reliability. It does not disappoint.

Dual PSU inputs and NICs (non-aggregation)! Keen on seeing how their remote software works.


This is a great use for some of the smaller CPU's we have been seeing for a couple of years now. I am sure we will see something of this nature with other mini chips by other manufacturers. I could see one of these or maybe even something a bit smaller (as noted by Taylor above) as a household backup unit.

HP has had their Proliant Micro Server powered by AMD Athlon II Neo N36L Dual core processor out since Q4 2010. The only thing WD has done is specifically taylor their MicroServer to do a specific function and have the software packaged with it to do it.

These little servers are quite nice for development boxes and useful as swing servers for swing migrations, plus they are cheap. The only issue is now the Dell Poweredge T110's prices have come down so much you can get a Sandy -E based Xeon quad core and 8 Gig of RAM with Lots of hard drive space for a little bit more than these MicroServers are selling for. They have their niches and i still like them as Development boxes as they are weak enough to usually warrant getting a server upgrade or new server to use a program instead of trying to turn a dev box into a production box.


For smaller businesses this will be a good choice. But how about the cooling system?


Very happy with mine, which I use at home for backing up my 20-year photo/video collection (1.6Tb) and the Family PC's. Love the high-reliability drives that come with it (I went for the 8Tb version, which gives me 5.4Tb useable space). Very small and quiet. Uses 41 watts according to my UPS. I like the automagic support for UPS via USB too - a requirement for RAID I would say (having lost some data this way once - corrupted by RAID rebuild after power cut). Love too the second power supply support (got one from WD's web site) and the support for teamed NIC's (it only comes with one cable though so I bought a second). I got CrashPlan installed on mine to back it up to the Cloud, too for extra relaibilty. Worth the investment, I would say.
