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

Pros: Purchased 12/2/14 Now it is 2/23/15 and this item has quick working. Computer won't load this external hard drive Keeps saying in order to load I have to format the disk. I did that when I first received this and now have programs on it and it wants me to reformat. Even when I gave up and tried to format the computer could not find it. The drive light just start blinking and nothing happens.

Cons: See above

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

Pros: Fast transfer speeds, large amount of storage

Cons: Caution! this is not the same product as WD Mybook live. WD no longer makes the Mybook live, which was a NAS devise. This Mybook is a direct connect device not capable of being an NAS or acting as a media storage/server for a network.

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

Pros: Large amount of space, fast transfer speeds, WD's warranty service

Cons: First one quit on me about a month into use. Started to smell funky and actually started smoking.

Other Thoughts: Western Digital was quick to ship me a new one, sending out the replacement within 24 hours of receiving my faulty drive.

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?!?!
