With NoTouch Ramp Load technology, the recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit. StableTrac - The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations which enables consistently higher performance.

2 out of 5 eggsHigh Failure Rate

Pros: Good speed
Good performace
Great RMA tool

Cons: High Failure rate
Became very familiar with RMA tool

Other Thoughts: We purchased 16 of these drives in 2013. Of that shipment, 2 of the drives were bad. We RMAed them. Western Digital has a great tool that lets you do advanced RMAs (they send the drive to you first if you give them your credit card) completely online without a phone call. Since 2013 we have RMAed 10 or so of these drives. In the most recent RMA I received two new drives, but one of them was bad. I can only assume this model has a rather faulty part in it. We had a similar experience with a batch of 3 TB Seagate drives a few years back (lookup Backblaze's hard drive realiability ratings). These kinds of things happen, I'm glad we have a solid 5 year warranty and RMA process, but I know I'm going to be replacing a few of these every year and in a couple years we'll have to replace all of the drives before the warranty expires. With Seagates' 2 year warranty we simply had to replace all of the drives around the 3 year mark because they were failing in droves and the warranty was out.

1 out of 5 eggsHigh Failure Rate

Pros: Pros: stores data like any other hard drive when it's working

Cons: I bought 10 of these; 8 in use and 2 are cold spares. I've now RMA'd 6 of them. So 6 out of 8 in use have failed in just over 2 years. I have two other platforms; one with a pool of hitachis and the other with a pool of seagates, and both are rock solid compared with the oft-failing western digitals. I used to be a wd fan, but this bunch of WD4001FAEX drives changed my thinking. To be fair, the warranty turnaround is quick, but it's not great to pay shipping for so many RMA's.

1 out of 5 eggs2 of 2 Failed

Pros: Large, fast, relatively quiet

Cons: Failure rate

Other Thoughts: I bought two of these drives in August of 2013, one to use as a Time Machine backup drive for my laptop, the other to use as a storage drive attached to my media center Mac Mini. Over the past year, the backup drive has become unreadable several times, requiring me to reformat and start from scratch with a fresh backup. The media drive recently failed, and now makes a clicking sound when powered up.

5 out of 5 eggsPleasant surprise

Pros: Big, fast

Cons: very slow to wake up

Other Thoughts: At end of Jan I originally bought a WD BLACK SERIES WD4003FZEX 4TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive. It was DOA. WD quickly sent me a replacement. I just noticed today (ok, sometimes I'm slow) that instead ot the WD4003FZEX, they sent me the much more expensive WD4001FAEX. Hard to beat that for customer service....

1 out of 5 eggsHigh failure rate

Pros: Large drive, fast, reasonable cool

Cons: 4 of 6 drives failed within 3 months, one other within 6 months

Other Thoughts: Purchased these drives for the warranty, and paid accordingly. First drive worked well in NAS. Ordered a second one...wouldn't boot. It was a gift, so past the 30 day window. RMA to WD. Replacement drive DOA. RMA again. Replacement of the replacement failed SMART. RMA for the 4th drive, finally working (for 4 months so far). The initial drive, which prompted the subsequent purchase, started throwing SMART errors at 5 months. RMA to WD. This replacement just died after 3 months. So, of 5 drives I have had in my hands, only one works now. WD initally gave the RMA drives a 6 month warranty, instead of 5 years. I complained and they gave me back the 5 years. Frankly, if I have to RMA every few months, at my shipping cost, it isn't worth it anyway. I am going to RMA the current dead drive, but I won't be putting one of these back in any NAS that I need to use daily.

Manufacturer Response:

Greetings Lotek, please accept our apologies for any inconvenience you may have experienced with the WD Black drives. Given the application you are utilizing these drives for, you may be interested in working with the Red line of drives, which is intended for 24x7 operation in NAS enclosures with up to 5 bays.

Regardless of the reason the drive has failed, we stand behind our warranty and would like the chance to replace your device at no further cost to you, while providing you with a positive resolution to your overall experience. Please contact us by phone or email below and when you speak with our support staff be sure to reference this Newegg review along with your previous WD RMA number.

1 out of 5 eggsIt worked for 6 months

Pros: when it worked it worked great

Cons: After the first six months of installing this drive I had barely used it. Only after six months i started using it and it then broke after some minor use. The first signs of it breaking was that it made a repetitive "clicking" sound, where after that I tried to use data from it, which caused my PC to utterly crash.

Other Thoughts: Now I can't even access the HDD in the BIOS. I am very frustrated and disappointed by the whole thing...

Manufacturer Response:

Greetings, please accept our apologies for any inconvenience you may have experienced. Our drives are rigorously tested to ensure they are in good working condition before they leave our warehouses. We understand your situation and will gladly replace your in-warranty drive directly, so we are able to investigate the cause relating to the products defect.

4 out of 5 eggs*Update* Use for Archive storage only

Pros: -High capacity
-Simple Installation (What SATA isn't?)
-Standard Drive Height (IE: Will fit in any machine)
-Not Overly loud (You can tell when it spins up, but only then)
-It 'tests' fast, but I'm not sure it's as fast as they say it is.

Cons: -Not 1Tb/Platter = Slower access
-Drive likes to power down (conserve power) and/or not Spin-up until needed. (causes a delay when initially accessing of upto 5-8 seconds)

Other Thoughts: So I've had this a number of months now (enough to feel comfortable to have it house my archive data, music, etc) and as an Archive drive it's great. Lots of storage and I'll probably not Need another Archive drive for a while.

I also wanted to use it to house my music, video, and picture archives while allowing access to them without delay. Now there's always a slight spin-up delay when you first boot a disk (from cold boot), but that should be taken care of during the boot. This drive will remain completely spun-down until you first access it. This causes a huge (in relative computer time) delay between "do this" and it actually doing it. The delay is big in Windows, but in Linux it actually causes the OS to almost lock up as it tries to mount the disk. Linux throws an access error, but shortly afterwards I get the window I was waiting on. I'm not sure how Mac OSX handles it as I can't remember at this point if I've tested that yet. Yes, I have (more than) triple boot. ;-)

I haven't done video encoding yet using this drive as a source/destination, but I think I'm going to bypass that, just use my SSD for the encoding, and then throw the file on the 4Tb drive after I've done my editing.

In summary, use this for Archive/Backup purposes Only, not for an everyday use drive.
