2 out of 5 eggsGetting slower

Pros: Easy management of shares, large space, multiple raid options

Cons: Services such as iTunes server don't work as advertised and transfer speeds started slow and became worse.

Other Thoughts: The transfer speed on this has gotten so slow that my wife and I are thinking about ditching it all together and getting 3TB USB3 drives. It takes almost an entire day to backup one of our pcs.

1 out of 5 eggsDOA

1 out of 5 eggsVery Slow

Pros: Raid 5

Cons: Very slow. There are a lot of discussion groups out there about the slowness of upload to this device. The problem stems from WD not putting a fast enough processor in this system. Yes it has a gigport nic in it, but you can only upload around 10MB/s so that doesn't matter. Trying to transfer over 1 TB will take you about 24 hours.

Other Thoughts: If you are strickly looking for a high storage capability and speed doesn't matter, then this device is for you. However, if you plan on doing a lot of transfers back and forth from this device, look elsewhere.

4 out of 5 eggsWD ShareSpace Initial reactions

Pros: Big....pretty fast....easy setup* .....I needed a lot of extra space on a RAID 5 setup and this does it for a great price.

Cons: Active Directory integration seems pretty mediocre.

Other Thoughts: This is a strange product. It doesn't REALLY feel enterprise, nor does it REALLY feel home. I'd put it in the "home device for people who work in IT" category. Were I a typical home user I'd find setup difficult -- there a few places where a careless user could brick their system.

Without knowing I'd be willing to wager that most of the really negative reviews of this product came from people who stumbled on configuration.

Thing really has no place in a giant business either though.

All that being said, I needed a ton of extra space, RAIDed, and seperate from the rest of our fileserver stuff, and it seems like this will fit the bill nicely.

3 out of 5 eggsConsistent Battle

Pros: This device has one main point for its buyers. It has alot of storage for a decent price.

Cons: I've had to battle with mine to make it work properly for me. First time out of the box it booted up fine, but after a about an hour I noticed it had lost its array. Meh - Whatever it wasn't like I had anything on it. (Although it took almost 24-30 hours if my memory serves me) Now about 2 months later I notices that the System Error light is blinking red while the device is currently working just fine. I log into the device and find out the device has been kicked into "Degraded Mode". I know very little about RAID so I hoped that a reboot may just clear the cashe and fix it. Nope.....Drive 2 is now showing as failed (which I assume caused the degraded mode). I'm very tolerant and still very happy with the device. Its leaps and bounds better then my 2TB HD that I had that crashed and lost everything (sad panda). But, the fact that the device has been fighting so much has me worried what other errors or issues it will bring up in the future.

Other Thoughts: I love this device. But with the amount of issues I've reviewed before and after owning this device it makes me wonder if I should buy another RAID to backup my RAID lol.

Manufacturer Response:

We apologize for the inconvenience this may be causing. RAID is the utilization of one or more disks in order to allow them to behave as one large drive. RAID 5 provides for hardware redundency and is not a backup of your data. We would like to further assist you in resolving any issue you are having with our product, as the behavior you are experiencing it not typical of our device. If you would like to contact us for further support, please visit: http://support.wdc.com/rs/ Copy and paste the URL of this review where indicated and provide the requested information and one of our technical support staff will be contacting you regarding this issue. You may also contact us at 1 (800) 275-4932. In the future, you may also want to consider posting your issues to our WD Community where you can interact with other WD customers. www.community.wdc.com

4 out of 5 eggsNice little home storage device

Pros: Plenty of storage for the home user. Small footprint and low power consumption. Web user interface is fairly easy to use. Provides shell access for more advanced usage outside of the user interface. Runs quiet. Light indicators aren't obnoxiously bright so it's safe to leave on if used in the same room you sleep in.

Cons: Not able to hotswap drives. No easy access to drives. Very slow.

Other Thoughts: This device is essentially an ARM based Linux based storage appliance. Thanks to WD providing shell access, I actually wrote some backup scripts that run from it to back up various other computers at night. I can also do some monitoring on it that you can't do without the shell access.

Despite the fact it has gigabit networking, it can't fully utilize it due to the poor performance of the system and the fact that it is completely software RAID (there is NO raid controller in this device, RAID is managed by Linux mdadm). I have been unable to exceed 10 mb/s while using RAID5 on the device despite the fact that I have confirmed it has a gigabit connection to the switch. It is, however, fast enough for streaming h.264 1080p video.

This is a great little NAS appliance, but I would not use it anywhere except at home with no more than a couple simultaneous users, where it is designed to be used.

2 out of 5 eggsWD slow to fix critical bugs

Pros: Very easy to setup, and configure for a home or small office setup

Cons: This device seems to have a fatal flaw when operating in RAID 5. If power is unexpectedly lost to the device while it is performing a RAID filesystem check (which can take many hours) the RAID configuration is lost and the device believes one or more drives have failed.

Currently the only way to recover from this is by manually rebuilding the RAID array from the command line. WD is aware of the problem, but as of yet, they have not released a firmware update to address this issue.

Other Thoughts: Before the above issue, the only other issue was that the write speed across the network was not very fast. I've seen some complaints about this on WD Community forums, and it may have been addressed in a firmware update, but the updates are not yet available.

Manufacturer Response:

We apologize for the inconvenience you have experience regarding our device. RAID 5 is a format of RAID that allows for data to remain intact should a single drive fail within an enclosure.

5 out of 5 eggsAwesome device

Pros: This device is great for the person that wants to keep their home movies or pictures safe. I personally rip and encode all my personal DVDs and put them on this device. I then stream them to my Mac mini using XBMC and it works flawlessly every time. This is a great device for anyone who wants to back up anything, and the FTP service on the device works like a charm.

Cons: none

5 out of 5 eggsGreat home media server

Pros: I have had this device for about 15 months now without incident. I initially purchased the 2 GB version and added 2 additional WD 1 TB drives without incident. It did take close to 24 hours to switch the raid from 0 to 5 but it has been solid since. I am running gigabit with jumbo frames and I typically get read speeds of 25 MB/s+ and write speeds around 10-20 MB/s depending on the size of the files being transferred. I used the FTP several times and there have been no problems. The ability to setup users is beneficial to secure the box a little bit more. This thing barely makes any sounds.

Cons: Only a single NIC. I have seen some bad reviews about the aftermath of a drive failure and trying to rebuild the RAID array but fortunately I have not experienced this yet. I have been wanting to simulate a drive failure just to know what I'm getting into but with all the data that I now have on this I will have to spend another $200 on hard drives to backup the data in preparation for a test. Hopefully it never gets to that point and I hope I haven't just jinxed myself.

Other Thoughts: This is mainly a media server for 2 PS3s. Twonky is a little flaky when the file extensions aren't avi or mpg. When I transfer mp4 or m4v videos I have to change the file extension and then change it back while it's on the server just so that it will show up when connecting from the PS3. All other file types that are compatible with the PS3 have worked fine. I have streamed multiple videos to both PS3's simultaneously without incident or any lag. For all the things that could go wrong with this product it has been a very reliable piece of my network. Recent SSH access is also a + but i have yet to really do anything other than restart some services when troubleshooting the file extension issue.
