5 out of 5 eggsAwsome!

This review is from: WD My Book 4TB USB 3.0/USB 2.0 3.5" External Hard Drive WDBFJK0040HBK-NESN

Pros: Work's Very fast when usb 3.0, for best I/O speed!

Cons: the constant parking of the drive heads can annoy you, but it to preserve the life of the drive. when active, alway's fast no prob.
the heads park after what seems 5 or 10 min, this keeps the drive cool and no physical wear to motor in drive and bearing's.

Other Thoughts: over all, I love this device, I have alway's loved WDigital, It is what you would expect from WD!

2 out of 5 eggsDisappointing

This review is from: WD My Book 4TB USB 3.0/USB 2.0 3.5" External Hard Drive WDBFJK0040HBK-NESN

Pros: Looks nice, decent speed for what I needed,

Cons: Dead after 5 months of minimal use as an external drive for a DVR. Haven't submitted a warranty claim yet, hopefully it gets replaced with something more reliable.

1 out of 5 eggs3 Drives, 3 failures

This review is from: WD My Book 4TB USB 3.0/USB 2.0 3.5" External Hard Drive WDBFJK0040HBK-NESN

Pros: A lot of storage for the price; relatively fast

Cons: I've bought 2 of these and they are in rotation as external backup drives to my NAS. Both drives have gone bad, and have been replaced under warranty. Now one of the replacements has failed! I don't care if the warranty is 2 years, the hassle of returning them and having my backups at risk just isn't worth it.

Other Thoughts: Each drive failed within 1 year. Would you trust your data to this solution? Upon faillure, each drive was tested using WD diagnostic utility, and failed SMART tests. Note that my NAS is using a WD Red NAS drive I'm happy with; it's been running no problem. But the MyBooks are trouble...

4 out of 5 eggsSo far so good, but...

This review is from: WD My Book 4TB USB 3.0/USB 2.0 3.5" External Hard Drive WDBFJK0040HBK-NESN

Pros: I've had mine nearly a full year now, it runs 24x7x365 attached to a PC that runs all the time, it's used with a 3rd party backup product that sycs backups to it whenever they happen on other drives, so this one is spinning all of the time. My PC is Win7 64bit, and boots up just fine with this attached to it as a USB 3.0 drive.

Cons: None so far

Other Thoughts: I wanted another one of these, and sometimes NewEgg puts them on sale of has special codes for them, but today I found out that their code, displayed on the page for all of us to see, was only good for people living in a few states, this was not something I anticipated from NewEgg?!?!

5 out of 5 eggsWorks as advertised

This review is from: WD My Book 4TB USB 3.0/USB 2.0 3.5" External Hard Drive WDBFJK0040HBK-NESN

Pros: Works as advertised. High transfer speeds, sleeps when not in use and has storage for days!

I use this to store media and as a secondary backup device. What more can I say? I have yet to have a WD device fail me. I had gone out on a limb and purchased a HD from another manufacturer. That device failed and I am back to WD again. Way to go WD!

Cons: None.

Other Thoughts: WD bundle software is pretty much worthless if you want any kind of custom backup jobs. Not sure why they provide this as the included software other than it is probably cheap or free license to WD. I wouldn't waste my time with it.

Because there are so many other options out there for backup software and are easily obtained, no egg hit here. Not a big deal to me.

1 out of 5 eggsI was living in a fool's paradise!

This review is from: WD My Book 4TB USB 3.0/USB 2.0 3.5" External Hard Drive WDBFJK0040HBK-NESN

Pros: Large capacity storage, but I really know because I got to store 992 gb before everything went kablooey.

Cons: Started flashing format drive after 6 months of use.

Other Thoughts: This isn't my first rodeo with an external hard drive; I've had two previous. The first one failed and I lost almost everything. With my second external, I took extra special care of it and three years later it is still working, but nearing capacity, so I bought the My Book on the recommendation of a computer tech I know, who had turned his nose up at my 2nd external hard drive, which was not a WD. Seven months later the WD My Book is not working, and says I need to format it. After a minor heart attack, I called WD support and was told that I can reformat and the My Book should work fine, of course I lose everything I have stored in the past seven months. I've got an RMA from WD, but after this I cannot seriously consider using the My Book again.

4 out of 5 eggsFree the beast

This review is from: WD My Book 4TB USB 3.0/USB 2.0 3.5" External Hard Drive WDBFJK0040HBK-NESN

Pros: Lots of room
WD Green inside
Works just fine for me.
Cheaper than an bare internal

Cons: Not enough air flow inside the caddy.
caddy not reusable, but I wouldn't anyway.
I removed an egg because while the bare drive is fine the bit encryption makes this drive impossible to restore data if caddy fails, and it will.

Other Thoughts: This drive had mixed reviews when I bought it, but it was really cheap, and I needed a 4TB so I took a chance. I immediately removed mine from the caddy, and formatted it. I have been keeping an eye on mine and haven't received any errors. External caddies are failure prone (heat, power fluctuations), so I am hoping the bare drive is just fine.
