    • Old Reliable - An Investment That Stood the Test of Time
Capacity: 1TB Style: Newest Generation
In 2015, I purchased the Western Digital 1TB WD Blue PC Internal Hard Drive, and wow; this workhorse is driving away like a champ even after all these years. How many products nowadays can you buy and genuinely expect them to still work over five years later? Although it's an HDD that may not compete with the speed of modern SSDs, it offers phenomenal storage capacity at an unbeatable price. With HDDs, you are granted solidity and reliability, always crucial elements in handling data. As it was said - "Old is Gold." But bear in mind, if speed and performance are your primal needs, then SSD could be preferable. The major bell ringer for me regarding the Western Digital 1TB HDD is the excellent value for money. This budget-friendly beef of storage is perfect for those looking to get an enormous bang for their buck. The drive still functions exceptionally well, six years post-purchase, without any hiccups. It also offers valuable features like Free Acronis True Image WD Edition cloning software which eases data migration. It's also important to note that the WD Blue PC Hard Drive boasts a Data Recovery Service feature. In terms of compatibility, it readily gels well with desktop systems, ensuring a seamless experience right through the installation and usage stages. Remember that it's painted in this excellent blue, stepping away from dull, conventional storage system shades. In conclusion, Western Digital Blue can be your long-lasting companion for those seeking a reasonably priced, hardy, and reliable hard drive. This 1TB workhorse of an industry deserves its five stars for dependability, capability, capacity, and cost-effectiveness. ... show more

    • Good price for capacity; slower with real data..?
Capacity: 8TB Style: Newest 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

    • Another great product from western digital.
Capacity: 8TB Style: Newest 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

    • Nice storage drives!
Capacity: 8TB Style: Newest Generation
Purchased two of these WD Blue 8 TB drives recently. The second one took almost a month to get here but it finally arrived. Both drives are working flawless so far. I don't intend to use these for gaming or consistent drive activities. Only purchased as storage drives where I can free up my NVMe SSD drives for mission critical operations. The drives must be formatted as GPT drives so you can access the full drive capacity. If you format it as an MBR drive it will only show up as a 2 TB because that's the limitations imposed upon you by the MBR standard. Once you initialize the drive as GPT, you should format it as required. These WD Blue drives yields 7.28 TB of drive space total after it's formatted in it's entirety. Don't forget to assign a drive letter or it may not show up on your screen. I purchased the "ORICO 3.5 USB C 3.1 Hard Drive Enclosure" for the secondary drive so I can use it as an external backup drive. It allows the WD Blue drive to work at it's maximum potential speed of 6Gbps via a 3.1 USB port. Most of the other drive enclosures operate at 3.0 speeds and would make drive backups slower than necessary on a 5640 RPM drive. With that said, I highly recommend these WD Blue drives for passive backup storage. Don't know if you should be using these for gaming and such. There is a reason they offer a WD Black drive for such activities. ... show more
