WD Sentinel

Plug-and-play installation - The easy set up process allows the small business owner or IT consultant to integrate WD Sentinel into your office network like a pro. The administration dashboard quickly guides the user through the set up process including adding users, setting up user access, creating public or private shares, and scheduling backups.

Easy maintenance - Replacing one of the pre-installed drives or adding an additional drive is as easy as changing a light bulb. Just open the door and swap out the drives. WD Sentinel does the rest. It seamlessly migrates the server to the appropriate RAID level and automatically expands the server's storage capacity. Connected users can still access critical business data while the drive is being integrated. No data loss. No down time.

Secure remote access - WD Sentinel is perfect for businesses with employees working in satellite or home offices because you have the security of knowing all your business files are safely stored in one place and remote employees can access them from any computer with an Internet connection. WD Sentinel also performs automatic daily backups so all of the files on all the computers in the network are backed up and protected.

LCD Display panel readily offers critical information - The LCD display panel on the front of the device allows the user to monitor the system status and critical alerts.

Realtime system status through the administration dashboard - View realtime updates for drive, RAID, and network status through WD Sentinel's dashboard, which includes easy-to-use task wizards to help the user set backup schedules, administer user accounts, and manage public and private shares.

A total solution with industry-leading technology partners - We combined hardware and software from industry leaders to deliver a reliable, secure and easy-to-manage storage server designed specifically for small office environments. WD Sentinel features:

  • WD hard drives - Featuring hard drives optimized for reliability, quality and performance.
  • Intel Atom processor - Built with the latest Intel Atom dual core processor inside, WD Sentinel DX4000 can easily handle a small business's day-to-day computing and file storage demands.
  • Windows Storage Server 2008 R2 Essentials - WD Sentinel DX4000 uses the tested Microsoft Windows Storage Server 2008 R2 Essentials operating system to provide the cost effective, reliable, and scalable storage solution a small business needs to quickly and efficiently organize, protect, and share critical business data using the familiar Windows user experience.

Leading-edge performance - With dual Gigabit Ethernet connectivity, WD Sentinel DX4000 delivers read speeds up to 100 MBps through the Gigabit Ethernet interface. That's four times faster than most network drives in this category today. For maximum flexibility there is also a SuperSpeed USB 3.0 port that offers connectivity for additional storage devices and up to 5Gb/s transfer rates.

Compatible with multiple operating systems - WD Sentinel includes the Connector software for Windows XP, Windows Vista, Windows 7, Mac OS X Leopard, Mac OS X Snow Leopard and Mac OS X Lion*. Support for major network file-system protocols enables cross-platform compatibility and file sharing among Windows, Mac and Unix/Linux operating systems.

*May require updating your system with latest MS and WD updates.

Stream digital media anywhere in the network - With the built-in DLNA media server, connected employees can access any shared media libraries on the network rather than maintaining copies on their individual computers. Companies can also stream digital content like videos, music, or digital signage for employees, vendors or clients using remote web access.

Size: 8 TB Verified Purchase
My hobby is photography, and over the last 20 years I've accumulated a large (1.6Tb) catalog of family photos and videos (I've digitised all my slides, negatives and video tapes in order to preserve them). They are hence very precious to me and I am fairly paranoid about losing them to a hard disk failure, so have over the years invested in a series of ever-larger external hard drives to back my collection up to.

Recently I did have a multi-drive solution (Western Digital My Book Mirror Edition 2TB USB 2.0 (WDH2U20000N)) - and it worked great initially (for a year or so) but as time passed the interface (USB 2.) was a bottleneck, it's a point solution (not on the home network - I have to plug it in to any PC I want to back up), and it only holds two hard-drives (my data needs grew too fast for just two drives). I looked at upgrading that to the newest version as of this writing (Western Digital My Book World Edition II - 6 TB (2 x 3 TB) Network Attached Storage - which can be on the home network so I can back up my other family computers too, and is quite capacious at 6Tb - but it's only two drives so if one fails it's toast (unless I configure it to only have 3Tb of space, which is insufficient), and capacity is still limited as it's only two drives (the problem I gradually had with the previous one).

I also looked at plugging external drives like the ones mentioned above into my home router (

Size: 4 TB Vine Customer Review of Free Product ( What's this? )
This is my fourth NAS. The others have been Readynas and Synology. This is also my first Windows-based NAS so part of my review involves a comparison with the Linux based NAS units. Overall I have to say that I'm disappointed. The hardware looks solid and I really like the trayless bays. Makes it easy to slip in a disk and there's no need for additional hardware.

On the downside (although some of the complexity is hidden) this is not an easy device to manage. It's basically Windows on a server with all of the regular Microsoft updates and the ability to install and configure it almost like a Windows box. The Linux based NASs are actually much easier to use and configure because more of the complexity has been hidden away. Here are some of my notes after using the Sentinel DX4000.

Physical - The Good
+ Can connect two power supplies
+ Two Ethernet w/teaming possible (unlike the Readynas Ultra 6+)
+ USB 3.0
+ 2GB RAM. Most of the NASs I've used came with 1 GB standard
+ Intel Atom D525 @1.8. Reasonable compromise between Power and power consumption

Physical - The Bad
- Power brick. Would be nice if the PS was internal.
- Loud fan. Doesn't quiet down on it's own
- Fan won't turn off when it's powered off

Hardware - The Bad
- Only takes expensive WD Enterprise Drives. Would be nice if there was a larger list of compatible drives but that probably would be unreasonable from a NAS manufacturer that's known as a drive manufacturer as well.

Setup - The Bad
- Very long boot time ("Loading OS... Please Wait")
- Must use Windows PC for Setup?
- Windows Server 2008R2 - regular updates etc.

We appreciate your feedback and apologize for the inconvenience you may have experienced with your Western Digital Sentinel DX4000, as this is not the intended experience with the product. The Western Digital Sentinel design incorporates the security and reliability of having the Microsoft Server 2008 R2. This added benefit along with our WD Guardian services provides the user with the assurances that their valuable data is backed up securely. Packed with remote access, easy maintenance, real-time system status, and an LCD display make this unit a great addition to any small business environment. You may learn more about the Sentinel's specification here: http://www.wdc.com/en/products/products.aspx?id=610

To start the setup process, we recommend reading the user manual thoroughly and using our connecting software. You may refer to the following link for the user manual: http://www.wdc.com/wdproducts/library/?id=297&type=25

The drives that are tested and supported to work with the Sentinel are RAID Class drives, which allow for 24x7 uptime and durability. You may refer to the following link for additional information on the specification of the drive found here:

http://store.westerndigital.com/store/wdus/en_US/DisplayAccesoryProductDetailsPage/productID.253980500/parid.59193300/catid.59243100/categoryID.59243300

In the event of a power interruption - (unplanned shut down) The WD Sentinel unit will automatically start a "verification process".

The "initialization process" does two primary tasks:

1. A 100% Verify of the Integrity of the RAID set up & configuration - Power interruptions can cause Data Integrity concerns for a RAID system.

2. Insures that there has been no data corruption as a result of the improper shut down or loss of power - Inadvertent shut downs can cause loss of Customer data. During the "initialization process" a client retains full access to the WD Sentinel & Data Access. The WD Sentinel will operate in degraded mode until the task is completed.

There are a few ways to reduce the likelihood of the WD Sentinel from triggering the Initialization process:

1. Implement a UPS (Uninterruptable Power Supply )in your environment - provides power for a clean shut down.

2. Use the power-restart button within the Dashboard for Clean shutdowns and or restarts.

3. Add a second power cord which is supported by the WD Sentinel (reduces the likelihood of an unplanned power condition).

4. Refer to the QIG Quick Install Guide for step-by-step onboarding instructions - process for a clean installation.

This Western Digial 12TB Sentinel DX4000 raid is the third Western Digital raid I have owned. The first two are WD Sharespace devices and have been humming along without a problem for more than three years.

My first Sentinel would not initialize and I spent two hours on the phone with the tech support guy who finally gave up and told me to return it. Note to engineering: it's a problem when you put the software on the device. If something happens to the device after it leaves the factory (cosmic rays, magnets, whatever) the customer is screwed and you have another return.

The second Sentinel set-up was no problem. After waiting for the thing to initialize (45 minutes) and installing the Windows software, I was ready to go. Or so I thought.

I made dinner and when I came back the device had started initialzing itself again. The front panel on the device said 0.004% had been done. I was shocked because I read about similar problems with the device but didn't think I was in the same boat. Wrong. It's been 24 hours and only about 15% of the drives have been initialized.

I called WD tech support this morning and got the standard line "It's supposed to take a long time to initialize." When I quoted the WD Tech responses on Amazon they escalated me to level 2 support and the guy repeated the mantra, "It's suppose to take a long time to initialize." When I quoted chapter and verse from WD support comments here on this site he put me on hold for 20 minutes and came back and said I must have pulled the plug or powered down improperly. Typical--blame the customer. When I said I had done no such thing and in fact the device and my two Sharespaces were on a UPS, he was sympathetic but continued to insist it must have been user error. I assured him it was not.
