What does the black disk blue disk green disk mean of hard disk? Also the master disk

The above is not right, there are too many words in this meaning, it is not easy to say, simply put, the black disk is generally used by the server with 10000 rpm, blue disk, desktop level, green disk, energy-saving noise is small, red disk...

Western Digital classification, black disk, the fastest. The rotational speed can reach 10,000 revolutions. Blue disk, ordinary disk, household much more than 7200 rpm. Green disk, slow, silent. It is suitable for monitoring panels.

In fact, it is the location of the hard drive.

Distinguish. 1. The applicable places are different.

Distinguish. Second, the disadvantages are different.

The blue disc is slightly louder than the green disc and the performance is slightly louder than the black disc. The disadvantages of green disks are poor performance, high latency, and short lifespan. Black** is higher than blue and green.

Distinguish. Third, the advantages are different.

Green disks are lower calorific, quieter and more environmentally friendly. Energy-saving disk, suitable for large-capacity storage; With IntelliPower technology, the speed is automatically adjusted between 5400 and 7200. The advantages of the blue disk are strong performance, ** low, cost-effective, and the speed is 7200 rpm.

Servers with large black disk throughput, high-performance computing applications, and high-quality server applications.

The essential difference between a black disk and a blue disk is speed and performance.

1. Speed. Blue disk: Ordinary hard disk, suitable for home use. The blue disc speed is 5400 7200 rpm. The advantage is that the performance is stronger, the first is lower, and the cost performance is high; The downside is that the sound is slightly louder than the green disk and the performance is slightly worse than the black disk.

Black disk: A high-end disk, suitable for game lovers. The advantages are strong performance, low latency, and large cache; The disadvantage is that it is high and the sound is louder.

2. Performance. Black disk: The control circuit of the hard disk is equipped with Western Digital's dual read/write chips, which can improve the read and write speed of the hard disk. However, due to the current performance bottleneck of mechanical hard disks, it lies in its working principle, not in the speed of the chip.

Therefore, the performance of this type of hard disk is not significantly improved compared with ordinary hard disks, and the effect is minimal. Generally, high-end users or enterprises can consider choosing this type of hard disk, which is still worth choosing for slightly higher read and write performance and good stability.

Blue disk: Blue disk is the largest CD R disc shipped on the market, and it is deeply rooted in the hearts of the people with its low price** and good compatibility.

The theoretical storage period of the blue disk is 30 years, in this rapidly changing information age, the general thing may have no use value for up to 3 years, so the advantage of the blue disk is that it is easy to use and sufficient, and the disadvantages are also obvious, and the data is likely to be lost under strong light.

Hard disk green, blue and purple disk means that the hard disk is different colors, different colors of hard disk have their own characteristics, green disk, blue disk and purple disk are mainly different in terms of performance, stability and noise.

1. Differences in performance

The performance of the green disk is lower than that of the blue disk, and the performance of the blue disk is lower than that of the purple disk.

2. The difference in stability

The stability of the green disk is not much different from that of the blue disk, and the stability is better.

The stability of the purple disk is better than that of the green disk and the blue disk.

3. The difference in noise

The power consumption of the green disk is low, and the operating heat generation is low, so the operating noise is also small. Minimal noise is generated in green, blue and purple disks.

The blue disc is more noisy than the green disc and the purple disc are both louder.

The noise generated by the purple disk during operation is between the green disk and the blue disk.

First, the speed is different.

1. Black disk: represents the high-performance hard disk of Western Digital. Some of the Western Digital brand drives have a black color patch on the drive label that can be distinguished from other Western Digital drives. The rotational 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.

2. 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.

Third, the applicability is different.

1. Black disk: The performance is stronger, and 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 read and write. Suitable for game lovers.

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

Western Digital HDD:

Black disks have the best performance, but they are also the most noisy.

The performance of the blue disk is average, and the noise is moderate.

Green Disk has the worst performance and the least noise.

Red Disk Surveillance grade.

Green disk, copy

The blue disk and black disk are mainly the western bai data hard disk.

1. Green disk, energy-saving du low-power consumption hard disk, mainly due to DAO

Black disk high performance comes.

Large cache speed fast source Suitable for: enterprise, server with large throughput use DU code: LS 32M cache ZHI blue disk.

Green disks are the worst, we generally use blue disks, and black disks are best used by servers.

The green disc is the worst, the blue disc is medium! Black disk is the best! It should be a large cache! It's faster! The best SSD

Black disk: God**, high performance, 10,000 rpm.

Only Western Digital brand hard drives are colored. Green represents energy conservation and environmental protection, hard disk is the most energy-saving, but the performance is the weakest; The blue disk is in the middle, and the general household is enough; Black disks have the best performance and efficiency, but they are the most expensive. It's not necessary for home use, it's better to buy an SSD directly.

Only Western Digital's hard disks are divided into black, blue, and green disks. Black disks are generally enterprise-level hard disks, focusing on stability and long-term operation, and are the most expensive. Blue disks are generally home desktop hard drives, which are the fastest and have good stability.

Green disks are generally storage disks that are mostly used to store data, movies ==, the slowest speed, and the lowest.

The design quality and manufacturing quality of the black disk are good, the head is double-processed, the stability is good, the performance is excellent, but the heat is large, the noise is large, if it is sensitive to noise, the blue disk is quiet, but the performance stability is not as good as the black disk.

No, the packaging is different, or it is different.
