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.

BUT...
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.

5 out of 5 eggsImpressive Storage Size, Fairly Low Cost

Pros: Worked right out of the box, 7200RPM disc speed, average transfer speed is over 100MB/s, 5 Year Warranty means that, unlike the other HDD manufacturers out there, WD is actually confident in their quality control and their product

Cons: None so far, but will update if there are any to report

Other Thoughts: Using this for storage, mainly movies and music, no stutter during play back of either. Could be cheaper, but then again, you DO get what you pay for in this world. Was a lifelong Seagate fan.....not anymore, WD has won me over

5 out of 5 eggsGreat Drive

Pros: Great speed, price was great around the holidays got 10 of them for 189 each to help complete 50TB raid for my home theater setup. The drives were OEM but packed in the factory shipping box which had them secured very well. Generally this is what has lead people to having bad experiences since Newegg is know for bad shipping practices with Hard drives. I am guessing since i ordered 10 at a time, that kept them from being wrapped in bubble wrap and loosely shipped in boxes. I have had them up 99% of the time since 12/9 and have done checks on them weekly with no drive going bad or showing issues. Set up in raid 50 crystal mark showed sustained sequential 810MB writes 1085MB reads through lsi mega raid card... So far I have been pleased with black drives. I have owned many over the years and knock on wood have had great experiences with them compared to my luck with other drives. I definitely would buy again but waiting for price to come back down from the current listing.

Cons: They do run warm but i have plenty of cooling for them in my raid enclosure.

5 out of 5 eggsExcellent

Pros: This drive is excellent! I was able to transfer all of my files over without any problems and it has performed at peak since I got it. The backwards compatibility from SATA III to SATA II/SATA I is great as my machine is older but I needed more space. Highly recommend!

Cons: No Cons as of yet, only had it about a month but I don't see any problems down the road.

5 out of 5 eggsBeen Great

Pros: I have 12 Black edition drives (ranging from 1TB to 4TB) and have been very happy with all of them. My advice is to sector scan with the WD software when you first get it to validate the drive. Then for normal operation put a fan blowing on them and they will make you happy! I use these for data storage so the usage is on the lower end but purchased them for the warranty.

Cons: None so far.

Other Thoughts: Food for thought:

4,000,000,000 Bytes converts to 3.61TB within windows.

What happens when we hit 15 TB? Can we finally do away with this misleading marketing scale?

15,000,000,000 Bytes converts to 13.97TB

2 out of 5 eggsDouble Jeapordy for me

Pros: 4TB and 5 year warranty does say quite a bit, however WD offers TWO types of 4TB Black drives. This one has proved to be problematic for me.

Cons: It was loud from the start, and was slooow. As usual, when I get a new drive I run drive maintenance utilities on it. The utilities showed 'no 64mb cache' and rated at only Sata II instead of Sata III. Although I purchased this drive during the holiday shopping season in December, I could've returned it to Newegg, Iron Guarantee and within the standard refund/exchange period. I instead RMA'd it with Western Digital.

I chose to be 'billed' for them to send me a new 4TB drive and then I'd ship back the faulty 4TB drive. This process placed a $300 hold on my Credit Card and the shipping label purchased from Western Digital was under $7 dollars.

I received the replaced drive, ran my utilities and it runs... ok. That's it, merely 'ok'. However it isn't loud nor does it make the 'clunking' and 'groaning' noises the previous drive did. Strangely, it still is not registering any cache on the drive nor is it showing that it is Sata III 6g. It's performance is merely 'ok'. I won't buy again.

Other Thoughts: I'm stunned. I have a WD 640 Black that is just recently showing it's 'age'. I also have Seagate drives in several PC's that are running incredibly well over the last years I've owned them. I run the same Perfect Disk, Spinrite 6.0 and other utilities to maximize the health, performance and longevity of my drives. The 4TB WD Black is my 'poorest' preforming drive.

Pros: Unit was dead on arrival. I could hear the actuators clicking, but it was most definitely toast when I got it. It shipped over

Cons: Awaiting replacement through newegg RMA.

5 out of 5 eggs4TB

Pros: Speed - Benchmarks show ~180MB reads, ~165MB writes (real life performance varies, ofcourse). Games load much faster than the 5400rpm drive I was using. Benchmarked on the onboard Sata 6 ports of my MSI P67A-G45.

Size - It's 4TB?

5 year warranty, which is becoming an endangered species in consumer grade drives.

Cons: About what I expected going from a 5400RPM drive I was using.

Audible over my system fans, which aren't exactly quiet.

Runs a touch warmer

Not exactly a con but a newer version came out right after I got this drive :/ Not worth sending it back in my opinion.

Other Thoughts: Hoping I have better luck with this drive than the past few WD drives I've used, but I've heard good things about the Black line.
