Does the Western Digital Green Group Disk Array affect performance?

The main factors that affect the performance of the array are as follows:

1. RAID level.

RAID 0 is the highest, because it is only striped, there is no protection for data, and multiple disks can be read and written at the same time.

RAID5 Secondly, while striping, the verification information needs to be calculated when writing data.

RAID 6 is the slowest and requires two checksums to be computed when writing data.

2. Processing performance of radi card or controller chip. The computing power of this chip determines how quickly RAID can be established, data can be written, and recovered.

3. Cache size. The larger the cache, the larger the IOPS and the faster it responds to the front-end host. After the data is written to the cache, the host defaults to the read/write operation.

In the background, the data is then written to disk by the cache; If the cache clearing algorithm is appropriate, the read data operation can be completed in the cache, which can greatly improve the read performance of the array.

4. Disk random write performance. The number of disk revolutions and the capacity of a single disk determine the seek speed of a single disk, that is, the disk performance.

The green disk has good comprehensive parameters such as performance, power consumption, and noise, and is suitable for general home users. In addition, after RAID 0 is established, the bandwidth of the back-end disk will be doubled, and the performance will be greatly improved.

However, the performance of the green disk is not as good as that of black and blue, which will have a certain impact on the performance of the array.

The performance will of course be affected if the speed is low, the green disk is not the pursuit of performance, the advice upstairs is good, if you only have the green disk, it will be on it.

It is difficult to understand the use of a green disk for RAID, it is best to use a black disk, and use a blue disk if you think it is loud.

Hello. Is your hard drive just used for storage? Or do you want to use it to install the system?

If the hard disk is only used as a secondary disk and you don't want to group RAID, it will be more suitable to choose a WD green disk.

The WD Green Drive is powered by IntelliPower technology, which is power-saving and quiet.

It also has a large capacity, ranging from 500GB to 6TB.

As for the rate of hard drive damage, I think it depends on personal factors and environment.

Regardless of the brand of hard drive, users must take care of and maintain it carefully. Many times, it is due to personal negligence that causes hard drive corruption.

In general, if the data on the hard drive is very important, I would recommend that you back up to several places, even if one of the hard drives is broken, it will not cause any data loss.

Here's some hard drive care knowledge:

Don't shut down your hard drive at high speed.

Do not restart your computer immediately after shutting it down.

Prevent high temperatures from causing bad sectors in the hard drive.

Clean up your computer's junk files regularly.

Do not move the computer while it is running.

Protect against vibration and be careful when holding the hard drive by hand.

To prevent computer viruses from damaging the hard disk, the hard disk should be disinfected regularly.

Prevent dust from entering.

We hope you find this information helpful.

You can use MHDD to test whether the hard disk has bad sectors, in general, the black disk is the best, and the green disk is the worst.

After reading the description, I think that the landlord machine configuration is low.

Of course. If the group RAID 1 is completely fine, strengthen the reliability.

If you want to group RAID0, it is strongly not recommended, on the one hand, the speed requirements of the warehouse disk are not high, on the other hand, the reliability of the green disk is low, and the group RAID0 is easy to fail and lose all data. Just mount it directly.

Yes, but it will waste half the space.

Western Digital classifies its hard disks by color, and the characteristics of its purple and green disks are as follows:

WD Green Disk: Suitable for daily use by ordinary computer users, used as a backup storage hard disk. It is characterized by large capacity, low capacity, high cost performance, and relatively low performance and stability.

WD Purple Disk: Ideal for monitoring environments, it can support up to 32HD lenses. Its market positioning is slightly higher than that of the green disk,**, and the stability is also higher than that of the green disk.

I think if you use a black disk, you can think about it.

bairaid0 because of the black disk quality.

DU is very good, it will not be bad in a short period of time, and the sex DAO can be good, and the group raid0 small file read performance is very impressive after doubling! If it's a green disk, forget it... The read and write performance of small files in group raid0 is also not good, so let's use raid1 for security.

The main function of raid1 is mirroring: the data that exists in the DU surface can be used separately. dao

The main function of radi0 is to speed up: if a hard disk is damaged, all the data in it will be lost.

It is recommended that you set up a raid1 comparison insurance to ensure the security of your data. Although raid0 can be accelerated, the speed will not be mentioned too much.
