  • Got a lemon, but it was replaced within a day. Can't complain now.
Capacity: 8TB Style: Previous Generation
I ordered this a few days back and it came yesterday. I installed it as soon as I got home from work, created a partition in the same way I've done a million times before, but something either went wrong there, which I don't think happened. I've been installing and partitioning drives since I was like 10. I'm not saying it's impossible I screwed up, I'm saying it's very unlikely. The computer I installed it in also booted slow which it shouldn't because it's a brand new, high end workstation PC booting from an M.2 that I built myself to perform very specific tasks. It normally takes 5-20 seconds to boot from dead cold. With that drive installed it took about a minute, which your average PC user probably wouldn't even notice. But I'm not an average user, and I certainly did. It also gave me issues when trying to render with Blender or open CC4, Substance Painter, or any GPU intensive program. Even Halo CE was laggy and that's hardly a dent on my GPUs at max settings. I can play Halo and Render animations at the same time most nights. I'm not sure what that was about, some sort of bottleneck in my machine somwhere, because when I removed the drive and wiped the partition, everything worked fine again. I'm fairly sure there was a fault with the drive itself. I first noticed when it only showed 8gbs of capacity. I've seen USB sticks do this, but it's almost universally because that portion of the memory is unallocated. This was not unallocated, it was simply not present. I tried every formatting and recovery trick I know to no avail. Even tried a few paid recovery programs with no luck. At first I thought I just screwed up, but with each recovery and formatting methods I tried that failed, the more I was convinced I didn't screw up. Finally around 11 or so at night, after hours of trying I gave up and submitted a request for a replacement which came already today. I just installed said replacement moments ago. No issues what-so-ever. Installed fine and reads exactly as it should. So, yeah. I did apparently receive a dud on the first go, but Amazon was quick to replace it and the new one has no issues thus far. WD has always made good equipment and I stand by their HDDs even still. This was the first problem I've had with WD drives in many years, over a decade. I've had VERY old ones become corrupted, but never had one not work right out of the box. Again, I want to stress that this was last night it all happened. Amazon got a replacement to me in less than 24 hours, so yeah. No complaints from me. Everything is working and I'm happy. Would buy again. ... show more

  • Another great product from western digital.
Capacity: 8TB Style: Previous Generation
I have been building computers since them came out and I only use WD hard drives. they are reliable, cost effective and they last. This drive is no exception. I use it for my plex server so it gets a ton of use and like the 6TB Blue already installed has work flawlessly. Also of note is that me personally have never had a WD drive fail. For media use or data storage this drive is a great choice but I would not recommend for gaming as it is a platter drive with a speed of only 5640Mb/sec data transfer rate. It would just make load times very slow, and quite frankly the WD black line of drives are a better chose for gaming as they are made for it. Great product. ... show more

  • Good price for capacity; slower with real data..?
Capacity: 8TB Style: Previous Generation
8tb "newest generation" model. Shipped in fairly uninspiring packaging, but seemed intact and sealed with tamper-resistant tape. As soon as I got this drive, I formatted it and ran h2testw to verify that all of the space on the drive was usable. When I began this process, I was getting about 180MB/s write speeds at the start of the disk. The verification completed successfully, and then I formatted it again and started copying my data to it, which consisted of multi-gigabyte video files. For some reason however, I was getting about 120-130MB/s speed the second time around, even though I was copying from an SSD. Not sure why. SMART data shows no problems. Running a benchmark writes at the full speed. Probably something to do with type of data, though I usually only see that with SSDs. Either way, keeping this since it fulfills the need for more space on the cheap. Will likely update the review if something goes wrong. ... show more

  • Dependable storage drive.
Capacity: 4TB Style: Previous Generation
I've had mine since fall of 2019, and it's still doing fine. I use mine as a storage drive, nothing very demanding. At 5400 RPM, I don't think this would make a very good gaming drive. You'd experience some hefty load times. 5400 is just fine for storage though. Videos, pictures, projects, whatever. A cheaper solution for your mass storage needs. This is an internal HDD, not an external, so installation is required. It's a simple process as far as PC building goes, but if you're not comfortable opening your case to mount it and plug it in, you might want to consider an external one for your storage needs. Those just need to be plugged into an outlet, and a USB port on your computer. It is pretty easy to install even if you've never done it though. It's only going to fit in a couple places, of which you can use any of those slots. Power and data cables are pretty goof proof too. They're designed so only the proper cables will fit, and only the right way. I'm sure you can find a few dozen videos online to help you with this. ... show more
