There was a problem filtering reviews right now. Please try again later.
Do yourself a favor, and read the reviews of how horribly slow this monstrosity is. Read every one of them and believe them thoroughly, because they're all true.
Then, read WD's exceptionally pathetic, inadequate, irrelevant response to almost every negative review, where they say to update the firmware. You see it over and over and over, here and in their support forums...
"Update the firmware..." "Update the firmware..." "Update the firmware..."
So what WD is really saying is that all its customers are fools and imbeciles. They think us incapable of any meaningful sentience.
This unit has automatic updates built in to the dashboard default values. The very FIRST thing it does, after installing and connecting, is update the firmware. Then, if you haven't already done so, it REPEATEDLY asks you to update the firmware every time you log on.
My guess is, their response will tell me to update the firmware. Who's taking bets?
Then they will ask me if the power cord is plugged in. (okay, that was a joke)
Then they will ask if I've connected the unit to a router with a gigabit LAN switch, which I have.
Then they will ask if I am using the ethernet cable that came with the unit - which is only a pitiful 2-feet long - which I am.
Then they will ask if... well, you get the picture. Anything to deflect criticism and responsibility from their product with ULTRA SLOW transfer speeds, which usually start in the 2-3mb/s range, and can actually climb as high as 12mb/s. Though that's rare. Transfers of 200gb usually take between 7-10 hours.
And what other people have said about the connection repeatedly dropping? ABSOLUTELY true. During any transfers of even a relatively small size, say, 50gb or more, there is ALWAYS an error that a file cannot be found. So you skip it, and the connection picks back up. Then you have to remember that file in order to copy it again. Try setting your alerts to notify you via email when the connection drops. Sometimes you'll get one every 5 minutes.
This also means that if you start a transfer when you go to bed, the drive will most likely have an error (which in Windows 7 will pause the transfer until you tell it how to proceed), and when you wake up, you've just wasted 8 hours. Congratulations, to both Western Digital and Microsoft, on their numerous contributions to the world's carbon emissions, and soon thereafter, its landfills.
I shouldn't need to heap more misery on top of this horror story, but I may as well give potential buyers the full flavor of what to expect for their thousand or so dollars. You can expect never to be able to multitask. What does that mean? I'll tell you what it means.
Let's say you are copying a file to or from this drive. While that's going, you try to copy, paste, move or rename ANY other file on the drive - you will get an INSTANT crash of both operations. This includes EVEN HAVING ANOTHER WINDOW OPEN for the drive. But that's not all! If this happens, NOT ONLY will you get an error; NOT ONLY will the files involved now be corrupted beyond repair; NOT ONLY will the files involved be fatally locked, meaning you cannot delete or cut or do anything to them; it also means that now you CANNOT perform any function without rebooting the drive! Hope your friends and family weren't using it for anything important.
It's too late now, but I wish I'd sent back this giant disposable paperweight. Western Digital, you should be ashamed for selling such a TOTAL PIECE OF GARBAGE.
Update - Worse than garbage. Much, much worse. Since I am stuck with this @#$!%!# piece of @#$!, and still need more room, I bought a 6tb external to attach to the USB port. Good idea? NOPE!!! This CRASHES the EX4 almost immediately, and makes it COMPLETELY UNUSABLE. You have to - GET THIS - disconnect and reconnect the power cord to be able to use the NAS again! This OF COURSE potentially subjects your data to corruption and the drive to damage. Two more attempts caused the same issue. UNFREAKING BELEIVABLE!
MORE FANTASTIC STUPIDITIES from western digital: You want to use RAID? Good luck with that. RAID does NOT work the way it should. If you try to set up a RAID 0, you are first limited to 16TB. Fine, this is stated in the specs. But if you have more total space on your HDDs, you SHOULD be able to use 16TB worth of RAID 0, and the extra as spanned. Does it work? NOOOOOOOO, it fails every time with a "drive failure". BS. The drives are healthy and fine.
Next, you are limited to using the Public share with: 1) the name "Public"; 2) the size of the first drive in the array. Want to change any of this? TOO BAD!
Next, if you want to use JBOD, you are also limited with these ridiculous "shares" by the size of each drive. Want to change the size of a share? TOO BAD! Want to make a small private share? TOO BAD! Want to choose a different drive for the Public share? TOO BAD!
And what has the DEGENERATE, western digital, done about all this? Not a GDF thing. You can google this issue and see many users have these same problems going back at least 3 years. I am looking into starting a class action law suit. These people should be put permanently out of business.
I buy a lot of high end electronics from Amazon but simply don't have time to write reviews. In this case, given my experience with this product, I feel a responsibility to share what happened in an effort to maybe prevent others from having the same problem.
I am a professional photographer and wanted to have a more stable and bullet-proof solution for backing up many TBs of files than simply backing up to a single, large external hard drive.
After a lot of research, the WD My Cloud EX4 sounded like overkill for my needs, but thought it better to err on the side of safety, since that is the whole point. I ordered the 24TB version thinking that it should be good for a few years (even with some loss of space due to RAID 5 configuration) to justify the large expense.
With four WD Red Drives in the RAID 5 configuration, I knew that with the redundancy, I could lose one of the four drives to a failure and still be okay. The WD Red drives are designed to go 24/7, so I thought this was a great feature (which now appears to be more of a theory than a proven, in my case). I also loved the idea of having all of my data available over an Internet connection, in the home or on the other side of the world.
So I set up the WD My Cloud EX4 and left it in its default configuration for RAID 5. It was fairly straight forward to set up. I set it to copy my main photo files over, with those files on a stand along 5TB drive connect to the WD My Cloud EX4 via the USB port in the back of the latter. The 5TB drive was nearly full, and the folder I was copying over was 3-4 TB. This ran for two days 24-7.
It seemed to have finished today, and I tried to access the WD My Cloud EX4 from my laptop (via Windows Explorer running Windows 8) over my home network, and it showed the folder I copied over to be empty...
I accessed it through the app installed on my laptop that came with the drive, and it showed a "Critical" alert.
When I clicked on the alert, it stated: "Drive failed in Bay 4. Replace the failed drive. Purchase a new drive at: www.wdc.com"
On the physical drive itself, on the LCD panel in front, it stated:
"Drive failed in bay 4"
It also had a red light flashing.
I went back onto my laptop, and then I got a new alert:
"Drive failed in Bay 3. Replace the failed drive. Purchase a new drive at: www.wdc.com"
On the hardware LCD, it now stated:
"Drive failed in bay 3,4"
Now both drives were flashing red...
So the whole point of this device and running RAID 5 is that you can lose any of the four drives and replace it and lose no data.
In my case, one drive failed right after the first, meaning I lose ALL of my data.
I went back to the log, and one failed today at 10:10:45 AM and the other failed at 10:10:46 AM. So within one second, two drive failed.
Thankfully, I just got this device, so I am not so deep into using it that this caused permanent damage. But it is going back to Amazon, and sadly, I don't think I could ever trust a WD product again.
It is too bad, because it seemed like it was going to be an excellent solution for my needs.
I attached a photo of the LCD read out and screencaps of the messages through the WD app to validate my statements in this review (and it should appear as a verified Amazon purchase).
