Western Digital 4TB WD Black Performance Internal Hard Drive HDD - 7200 RPM, SATA 6 Gb/s, 256 MB Cache, 3.5 - WD4005FZBX

Needed a much larger drive for my photos and music storage and this fit the task. So far no issues and it is very quiet. Transfer rate was very good, think I did 5TB overnight so not sure how long it took maybe 4-5 hours transferring from other drive as I did it before going to bed.

Ive been gaming on PC for years and after six months can effectively say this one is solid for anything. the r/w speeds are always at steady 7k as advertised. Its very quiet and honestly preforms better than my other samsung ssds.

I have yet to make a full review of the drive. Keep that in mind. That may take another year or two of continuous use. The drive arrived in a timely fashion, and it was no different from installing any regular 3.5 inch HDD. I intend to use it for weekly backups of my computer. Its still expensive to do so with an SSD, but so long as Im not in helium-filled territory, I should be fine.

It works like it should. Booted off of the disk I indicated. Just loud is all.

This review is for the 8 TB black hard drive. I have owned several different brands of hard drives and several different versions of WD’s hard drives over the years, including the greens, reds and purples. I have only have had one failure in that time, which happened to be worked hard, operating on a security camera server for a few years before failing. This is my first black as I wanted a reliable drive for backing up my desktop. These hard drives have a great 5-year warranty, which is one of the big reasons, I purchased this. I connected this drive to my Windows 10 computer with no issues. It took less than a minute to get setup and going. It was pre-formatted, so it was quick to a drive letter and get going. File transfer speeds are fairly speedy for a large size drive. I do think the drives are a bit pricey, but have come down in price over the last couple years. I currently have three of the black drives, this 8TB, a 6 and a 2TB....all have been reliable so far. Overall, other than being slightly pricey, these are great hard drives with good speeds and good warranty that I expect to be reliable over the long term. 4.5 stars

5/23/14 This WD Black 1TB is used as my primary data drive. I use a Kingston SSD as my O.S. / application drive. Win7 volume creation and format went without a hitch. The xfer of ~500GB data from my WD Red drive to this new WD Black drive went smoothly. This new Black drive has much faster read speed and very respectable write speed compared to other 7200rpm SATA drives I have used thus far. I also noticed that when I booted to win7 from it (I loaded a backup boot partition in case my SSD failed) the speed was impressive. No, not nearly as fast as my SSD but much faster than my backup WDSE and WDRed NAS drives which are also 7200RPM SATA3. Ive had Seagate 7200 RPM SATA3 drives which are not quite as nimble. Alas, it was all too good to be true:( My super speedy Black drive started clicking & chunking after appx. 2.5 mos. Hey ... This happens sometimes with hard drives ... ok, no big deal, the drive came with a 3yr. Wd warranty. This is where the fun started: Went to WD website and spent appx. 1/2hr. in RMA process. Very easy. Sent my RMA drive back via UPS label I printed from WD website (very convenient). After appx. 7 days I checked the RMA status on the WD website. WHAT??? The model# I sent them does not match the model# they are sending me. I looked up the model# they were sending me and it was the slower / cheaper Blue hdd with only 1yr warranty. I called WD to confirm. They answered the call after a few min of going thru the phone tree. The person I spoke to was very polite and spoke with no language accent issues. He said they didnt have any Black drives to send so they sent the Blue. I tactfully let him know this was not acceptable and requested a WD Red or SE drive as a replacement. You would think I was asking the United States Congress to agree on something. I have talked to 3 different reps on 3 separate phone calls with no resolution. I have had numerous business dealings with WD in the past. I was in network I.T. for over 20yrs. I have never gone through this much trouble with WD. Politely offering no resolution after hours of my time does not cut it with me. All this over a $90 hdd. Ill update when the issue is finally resolved. UPDATE 5/28/14 I called the corporate WD cust. svc. line this morning. The operator was very helpful and made sure I was connected to a live person, not voice mail. The Customer Service rep was very polite and sympathetic, but most important he resolved the issue within 30 min. The only reason it took even that long was because we were searching for an appropriate replacement drive I would be happy with since they had no (Black) drives to send me. I couldnt believe he actually offered a very generous upgrade for my time and inconvenience, which I of course accepted. I have always thought very highly of WD products. My faith in WD service is restored. I cannot upgrade the stars on my review because I am not receiving a (Black) hdd. I will give WD as a company a very favorable rating and will not hesitate to purchase from WD in the future. Update 5/29/14 My replacement drive arrived today, ahead of schedule. The drive is installed as my primary data drive and is loading as I write this. The drive is everything WD promised. I am a happy camper:) Update 11/25/14 Since my initial review I have added the following Western Digital hard drives to my systems: (2) 4TB SE NAS enterprise class 7200rpm (1) 4TB Green 5400rpm (2) 1TB Velociraptors 10,000 rpm All my W.D. drives are performing well 24x7. I run full Lifeguard diags on them once per week and have had no issues. The point is: Western Digital hard drives, as a whole, perform very well under very demanding conditions. I am chalking up the initial issue I had with the Western Digital service department as a one time fluke. They really did go out of their way to make it right. UPDATE 6/16/16 Since there are quite a few hits / comments on this review I thought I would supply a quick update All my WD drives from 2014 are still running great:) 24 x 7. UPDATE 4/6/18 Since there are quite a few hits / comments on this review I thought I would supply a quick update Green drive failed last month. WD sent replacement with no hassles and quick ship processing All other WD drives from 2014 are still running great:) 24 x 7. Thank you all for your comments. I am happy to have been helpful:)

I transferred about 1TB of large files to this drive so far and am seeing sustained write speeds of 230MB/s, and bursts of 750MB/s for the first few seconds. I am sitting right next to it and I dont hear any noise at all. If there is any, its quieter than my very quiet case fans so I dont notice it. I ran the CrystalDiskMark tests and didnt hear any noise during that either, even thought that reads and writes many small files. See my test results image. Overall, I am very happy since it was about 4x cheaper than a similar sized SSD would have cost, and is about 2x faster than any other hard drive I have owned in the past. It really is super quiet also, so I dont know what other reviews are talking about. Maybe this 6TB version is just that much quieter than the 2TB or 4TB versions people are saying are loud? Or maybe WD just improved them (bought mine Feb 2023).

Great price and good storage. The drive is a little louder than I like. It isnt loud per say, but it is louder than the other components in my computer. You can hear it spin up and it occasionally...clicks...that isnt quite a good description but it is almost like you can hear the head reposition on the drive.

This drive replaces the older WD model: WD6002FZWX. I attempted to buy the older model as a brand new item on eBay, since that is the model I was replacing, and I wanted to replace it with the same make/model. However, the seller sent to me a used item instead. I had to do a return, and then wait around for a refund. Then I went to Amazon to buy the newer model WD6004FZWX - and Im happy with this purchase. The drive from Amazon has zero hours of use, and only 1 turn-on - as checked by my hard disk diagnostic software - so the drive is definitely new. The one from Amazon is quiet, fast, and reliable - and comes with a five year factory warranty, which I verified by going to the Western Digital website, and checking the serial number of my drive with their warranty lookup service. This is a good hard drive for the money - and I should have gone to Amazon first - instead of wasting my time elsewhere, trying to find an older/discontinued drive model as a new item.
