3 out of 5 eggsKind of Iffy

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

Pros: The thing is huge and I got it on sale for pretty cheap (~ $130). The USB 3 was certainly nice to have as well.

Cons: I can't say I'm too happy with it after all this time. It feels extremely slow. It also occasionally disconnects and quickly reconnects which has caused more than one file transfer to fail for me.

Other Thoughts: I probably wouldn't pay for one at full price, but the thing is still helpful to have. I might buy another one if it was a bit south of $100.

2 out of 5 eggsWD My Book 4TB

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 storage space

Cons: does not work properly with built-in Windows backup application.

Other Thoughts: I would not recommend this external drive for the average consumer, if you only want to use it as a dumping ground then it works ok, but if you want an external drive for everyday backups or as NAS storage get something else.

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.

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.
