I was astonished about this kind of "HD Black" from Western Digital.We bougth this 1 Gb device around ten years ago (maybe even before) because other cheaper disks were faulty and nearly every year.we had to change and reinstall.At current date we've been using it over 30 thousands "Power on hours" and nearly 2.000 "load cycles" as i do realise by analising disk statistics... also moving it along different desktops/mini servers along last decade!!!Also we keep care of it by using a UPS but certainly this specific disk "was born" with a good DNA!!!We hope all recent and modern WD Black series have the same duration as we're very happy for our experience... while simultaneously crossing fingers

I bought this to convert movie files to folders of tif images. (tif images are basically bit maps that can hold movie color space. They're huge.) It is able to keep up with the image processing program I have that outputs to that. The other hard drive I was using could not keep up and would slow the whole thing down.I'm impressed with the capacity and ability of this drive compared to the price.I'm taking a star off because this drive disappears for about 15 seconds every hour or so. Everything that's using it freezes until it comes back. I doubt that's normal behavior, but since I'm only storing temporary data on it, and it always comes back, so I don't think it needs a replacement.I don't remember if this has RAM or what, but when writing to it, it can take ... MoreI bought this to convert movie files to folders of tif images.

Then it slows down to about 160MB per second, plus or minus 10. For reference, gigabit ethernet caps at 115MB per second. (These are all numbers displayed by Windows OS.)

Pros: I cant tell you much about this actual drive yet...Ask me again in seven yearsI bought this hoping for speed and reliability weighed against price and based on previous experience of three 1TB black drives one of which has run daily for about seven years, another as a clone for back up so not running very often and the third for a Linux distro. But I have to say it is mostly blind faith. You pay a bit more and get a five year warranty which is no real help if you lose all the data, and my very first 1TB Caviar Black expired in less than a year! One just hopes they will expire as it did, with advanced warning rather than suddenly like an ssd! This 4TB is intended to replace a WD Green 2TB files drive that is no longer big enough but has also been running for ... MorePros: I cant tell you much about this actual drive yet...Ask me again in seven yearsI bought this hoping for speed and reliability weighed against price and based on previous experience of three 1TB black drives one of which has run daily for about seven years, another as a clone for back up so not running very often and the third for a Linux distro.

This 4TB is intended to replace a WD Green 2TB files drive that is no longer big enough but has also been running for six odd years as well.

In this review, you will not find a bunch of bench tests and load tests. Just straight up real world feedback from your typical gamer. I was hoping to get 2 years out of this drive with regular gaming etc. I’ll update if it dies for any reason.I took this drive out, hooked it up in my PC (3060, 12400f, 16gb RAM) and did a quick format. Renamed it and started loading games. This was surprisingly quiet, I anticipated it to be a lot louder being a purpose-built gaming HDD. It’s really not much louder than the fans running at 70%. It’s an HDD so you’ll hear it spool up and click etc, but I’ve never had anyone say they can hear it through my mic or anything.Downloading/writing games was quick. I don’t believe server speed can beat out the write speed on this drive. ... MoreIn this review, you will not find a bunch of bench tests and load tests.

It’s an HDD so you’ll hear it spool up and click etc, but I’ve never had anyone say they can hear it through my mic or anything.Downloading/writing games was quick. I don’t believe server speed can beat out the write speed on this drive. I’m running 1.2gbps up and down and I haven’t met a server that can get me a game at 10% of that. So no delays when downloading/writing.In use, it works extremely well. I’m using this for storage but I also play off the HDD. I keep my AAA titles on an SSD (WZ2 etc.) and really only have MSFS2020 as far as heavy load games on this. Honestly, it doesn’t load MSFS any slower than an SSD. Same goes for Snowrunner. They load right up and there are no issues playing through this HDD, and I play MSFS on very high/ultra. Sometimes the GPU struggles but the HDD does not.Overall, I would highly recommend this to any casual-intermediate PC gamer, ESPECIALLY if you plan to play through the HDD. If you’re running a 4090ti and 13900K, maybe put your games on an SSD (you can afford it) but this drive has done everything I’ve asked of it.Again, if anything changes I’ll update but for now, I’m glad I ponied up the extra coin for this drive over a lesser unit.
This is an SMR drive shucked from a cheap external drive. It's a great, very cheap way to fill 2.5 inch 15mm bays with a lot of storage. But know and understand what you are getting and your workload. SMR drives are good at reads and sequential writes, and are very bad at random access writes because they have to re-write a lot of data even if all you do is change a few bytes in the middle of something. Good for media or one-time backups, but bad for incremental backups, lots of small files, or some filesystems like ZFS. They have part of the disk that works in a conventional way and then transfer it to the slower SMR section later on when they can. If you are using it sparingly enough that it can keep up, you won't even notice. But if you are hitting it hard with a ... MoreThis is an SMR drive shucked from a cheap external drive.

Know your workload before you buy.
For Hard Drives, it's kind of difficult to rate until we've had them long term, to see if they're going to fail or not. I've only had mine a few months at the time of this review, but so far, so good!It's been very fast, and mostly quiet as far as these kind of drives go, and was a decent price for the amount of storage. It was easy to install and just what my new system was missing.I use the more expensive Solid State Drives for boot up and some of my main files, but I use this to hold all my general storage. That's worked out great so far, and the game performance on it is pretty nice.It gets very high marks on benchmarks for this type of drive. All will be well as long as it holds up. Only time will tell there.
I bought 2 6TB Black 3.5 inch hard drives directly from WD on March 9 2022. The website tracking is broken, it never showed these shipping, but a week later a small, (flimsy, falling apart, partially broken open) box arrived containing my hard drives. The drives were packed with no cushioning on the top or bottom and the cheap bubble wrap surrounding the drives was popped open. This terrible packing was very disappointing, but I hoped for the best... bad sadly the drives were either defective to start with (and WD knew it which is why the shipped like this) or they were damaged during shipping. One drive would not initialize, the other started but made a loud clanking noise/defective. I do not understand why anyone would pack sensitive electronic equipment like hard ... MoreI bought 2 6TB Black 3.5 inch hard drives directly from WD on March 9 2022.

I do not understand why anyone would pack sensitive electronic equipment like hard drives with no protection, unless they knew they were defective to start with and hoped I would not test them, put them on a shelf for later. I contacted what turned out to be the worst customer service from a large corporation ever. I tried the phone and email and all they ever said was "give us 2-3 day to look in to this". I did that for a week... WD showed they do not care/know the drives were bad to start with forcing me to open a paypal dispute to get my money back. I was stunned when WD had 14 days to reply... but NEVER replied to the dispute. At the end of the time limit paypal closed the case and refunded my money. It took me almost a month to get my money back. WD should be ashamed. I have purchased 20-25 hard drives over time from WD, and I guess I got lucky and worked... but every relationship is good until there is an issue.... then we see what is real..... WD is not real. WD is a terrible company in every department. I am disgusted at WD and I will never do business with Western Digital again.
Ordered WD 500 Gb (WD5000LPLX) Hard Drive 9/6/2018 and started to make noise. www.GoHardDrive.com did replaced HD on 12/5/2018 but with an old manufactured date of 5/13/2015. Now, in 7/2021 started to have many "blue screen of death" with error massage of "Memory Management". Ran check disk surface check and found more than 250 bad sectors. Ran WD own Western Digital Data LifeGuard Diagnostics software and after 1:20 min stopped extended testing with popup message "Too many bad sectors detected" (see photo). Obviously bad hard drive! Went to Newegg Product Order #437802571 of 500 Gb hard drive and said was past returnable. GoHardDrive is no longer listed as seller.

2 of these WD Black HDDs had I/O Device Errors from the beginning. One sounded different after 60 days, with a Current Pending Sector Count of 8, an Uncorrectable Sector Count of 1, and Error Code 7 the next day. The WD Black totally crumbled after 5 weeks, before it could finish erasing once. The physical device WD6003FZBX-00K5WB0 (not the filesystem) could not be recognized without being connected before starting Linux, but prevents booting beyond POST. It was connected while displaying the F12 boot menu (after POST and before Linux), and everything had Input/Output Errors except HDDSuperClone, which has been erasing the HDD at 1530 KB/s for 4 weeks. None of our other disks have ever fallen apart to that extent in under 10 years. Customer reviews strongly reflect ... More2 of these WD Black HDDs had I/O Device Errors from the beginning.

None of our other disks have ever fallen apart to that extent in under 10 years. Customer reviews strongly reflect the increase of I/O Device Errors with Western Digital products.The WD Support website blocks an RMA as "OUT OF REGION", despite being purchased from the official Western Digital Store and never crossing borders. "OUT OF REGION" means the product was originally sold in a different country. Western Digital used to provide Advanced RMAs for free, before requiring expensive deposits and a permanent $25 charge, which is never refunded even after returning the original. The $25 cannot be refunded even when an Advanced RMA is refused outside the customer's control. Western Digital has customers submit the $25 before knowing invasive identity verification is required to continue, with no option to cancel and refund the $25 by the time the customer gets to know.Western Digital uses Styrofoam instead of polyethylene foam because it's slightly cheaper. Styrofoam cushions much more poorly than polyethylene foam, and should never be used for an expensive HDD. Styrofoam is also toxic and nearly impossible to recycle. Polyethylene foam is not much to ask for, as it's also inexpensive plastic. The quality of the Styrofoam accurately represented the product. Western Digital previously used polyethylene foam before becoming a scam company.In August 2021, a bait & switch scam was uncovered with the SN550 Blue SSD. Western Digital neglects severe vulnerabilities in My Cloud OS 3, and says to buy a new WD My Cloud if your existing product cannot be upgraded to OS 5. Instead of providing updates, Western Digital will leave customers vulnerable until later in 2022, when networking functionality will be crippled, with a ransom to purchase a new device with OS 5. Western Digital claims to have determined it necessary to end support for OS 3, even though it is not fundamentally flawed, and the problem is the very lack of support itself. I have accurately recommended Western Digital hundreds of times over the years, and do not regret that, but the new CEO David Goeckeler has trashed the company.
I hadnt built a full system in 20 years but Ive been upgrading every possible component on used machines because it was much more cost effective. I get to my build and decide on a 4tb black from WD because its the right size and figure buying direct is going to give me any support I might need. Generally, hds are plug and play, easy peasy with a bios update. Nope, bios cant see it. MSI is offering service repair after the third ticket because they dont know why the mb can see my cd-rom, ssds, etc but not my wd hd. Turns out, a well known problem quietly swept under the rug is the #3 3.3v pin designed to allow mb control also prevents it from spinning and is therefore ' useless.Is it even conceivable than wd could offer a solution for customers prior to purchasing? ... MoreI hadnt built a full system in 20 years but Ive been upgrading every possible component on used machines because it was much more cost effective.

Absolutely. Do they? No. You get to spend hours of your precious time unplugging, plugging, booting, rebooting, reconfiguribg researching, reading only to stumble across guys putting kapton tape on the pins or modifing sata extenders to disable the pin. Hoping one of those solutions works. The topper is paying twice the price from a direct outlet rather than Newegg just so I can stare at it a little longer. Done shopping here. Why would any manufacturer do this?
