Model overview based on user reviews
The WD Blue Blue hard drive receives mixed reviews from users. Many appreciate its affordable price, quiet operation, and reliability, with some users reporting it has lasted for years without issues. However, others have experienced early failures, with some drives failing within months of purchase. The drive is noted for its fast performance for an HDD, but it is often compared unfavorably to SSDs in terms of speed and noise. Vibrations and noise during operation are common complaints, and some users have had to implement solutions to reduce these issues. Overall, while the WD Blue Blue is seen as a good value for basic storage needs, its reliability can be inconsistent, making it less suitable for critical data storage.

One of the best hard drives I’ve worked with =) By the way, I’m writing from it =) Low noise Practicality Price Reliable Fast Speed. Windows XP loads from it in 15 sec, and Windows 7 in 25 sec. No flaws =)  Ilmir Tagirov: use WD WD10EZEX more than year |
One of the best workhorses for an adequate price, I don’t need more than 1 TB, it’s an excellent file dump) Yes, there is the next lvl up in the person of nvme ssd, but you’ll pay a lot more for them) Price, practicality This is not a nvme ssd, haha, but they don’t exist, what else do you need from a hard drive?) |
Nice model, I liked it From this I can note its low cost and packaging Terrible sounds when you turn on the computer, and if you screw it in poorly it will vibrate a lot, but overall it’s quiet use WD WD10EZEX few months |
