How noisy is the Western Digital Blue Disk? The difference between Western Digital hard disks, blue

Hello friends, Seagate hard drive's reputation plummeted after the firmware door incident, but the 12th generation hard disk launched in 09 is very strong, it is the fastest hard disk among all the 1t hard disks of the same specification, and the noise and temperature control are very good, the performance is better than the Western Digital blue disk, and the 32M cache is also twice as much as the blue disk, which is worth buying. Solo is now using the Seagate 12th generation 1T, which is very stable. Of course, if there is a shadow on Seagate products, it is not impossible to use a blue disk, which will be slightly louder than the Seagate 12th generation.

There is basically no noise on the green and red disks, but these two things are strange goods, and the speed is strange! The blue disk is in the middle, and the black disk is noisy and fast! (Hurry up!) You can't do Seagate Barracuda at all! ）

Seagate 12th generation has come out of the firmware door You can buy it with confidence Seagate hard disk is characterized by high performance, but high noise, high power consumption, Western Digital blue disk, higher performance than green disk, noise and power consumption are also well controlled, recommended to buy.

I now bought a Seagate 1TB (ST31000528) hard drive, the noise is so loud that it annoys people to death, gurgling, or non-stop, it is also ringing when I don't use it, I regret buying it, the original Seagate is not like this, I hope you can buy other brands, I heard that Western Digital is less noisy. Be careful when you buy it

First, the speed is different

1. Black disk: represents the high-performance hard disk of Western Digital, and some hard disks of the Western Digital brand have a black color block on the hard disk label, which can be distinguished from other hard disks of Western Digital, and the speed is 5400 rpm.

2. Blue disk: the speed is 5400-7200 rpm.

Second, the advantages and disadvantages are different

1. Black disk: the advantages are strong performance, low latency, and large cache; The disadvantage is that it is high and the sound is louder.

Third, the applicability is different

1. Black disk: The performance is stronger, the ability to cache and process read and write data is very high, so it is often used on high-performance computers for fast storage and reading and writing, suitable for game enthusiasts.

2. Blue disk: ordinary hard disk, suitable for home use.

Blue disk: strong performance, low performance, high cost performance; The downside is that the sound is slightly louder than the green disk and the performance is slightly worse than the black disk.

Western Digital Hard Drive (WD) is a hard drive manufactured by Western Digital Corporation of the United States. Western Digital Corporation (Western Digital Corp) is the world's leading hard disk manufacturer. The company was founded in 1970 and began designing and producing hard drives in 1988.

Headquartered in Lake Forest, California, USA, it is one of the oldest hard disk manufacturers and one of the founders of IDE interfaces.

WD employs approximately 23,000 people worldwide. The company's manufacturing facilities are located in Malaysia, California and Thailand, its design facilities are located in southern and northern California, and its sales offices are located around the world.

In terms of sequential read and write speed, the green disk is 80MB s, the blue disk is 105MB s, and the black disk is 110MB s, which is not much different.

However, for the reading and writing of small files, the speed of the green disk is less than half of that of the blue disk, and the blue disk is about 80% of the black disk, which is determined by the ability of seeking and other capabilities.

In practical applications, small files are read and written a lot, so if the green disk is the main disk, it will be very slow.

In terms of quality, the quality of the green disk is very bad, and some of them are downgraded from the unqualified blue disk and black disk, which is generally about the same in three years.

The quality of the blue disk is relatively good, and the repair rate is very low. Just don't buy fake or very poor parallel goods, the kind of quality is very poor, and people who say that the blue plate is poor basically buy fake or parallel goods.

The quality of the black disk itself is good, but most of the people who buy the black disk are players, and the hard disk reads and writes more, so the repair rate is not low. But anyway, the black disk has a 5-year warranty, and the warranty is good if it is broken.

10,000 rpm hard drives (such as the Western Digital Raptor series) are of course faster than 7200 rpm! For faster speeds, there are also 15,000 rpm (such as the Western Digital Velociraptor series), and of course, SSDs.

The performance of a hard drive is determined by the spin speed first, then the capacity of a single disk, then the technical improvements, and the AAM settings. As for the cache, interfaces, etc., there is almost no impact. For example, the green disk is constant 5400 rpm, so whether it is a single disk of 667g or a cache of 64m, the performance is just like that.

Hello. Do you mean desktop or mobile? There will be a difference in the specifications of the two:

Hopefully, this will help you in your choice.

The black disk is enterprise-grade, and the theoretical service life is longer than that of the blue disk.
