What is an enterprise class hard drive? What s the difference between it and the normal one?

Enterprise-class hard drives are usually SCSI hard drives with high spin speed.

Hot-swappable. **High.

Stable working for a long time.

The difference, there must be a difference in the model, the biggest difference is the interface, enterprise hard disks are generally SCSI, and the common ones are now SATA, and the bigger difference is,** (laughs)

Enterprise-level pursuit of stability, can work for a long time. The ordinary class pursues practicality and speed, and is fast. Many.

The enterprise-grade is more durable, more suitable for long working hours, and of course, higher.

Server hard disk) In order to make the hard disk adapt to the working environment of large data volume and long working time, the server generally uses high-speed, stable and secure SCSI hard disk (this is old news). But now, with the development of hard disk technology, ordinary SATA hard disks can also be used in low-end servers, of course, high-end servers still use SAS hard disks (the evolved version of SCSI hard disks). There are also server hard disks that are definitely much better than ordinary hard disks.

And it's hot-swappable.

Enterprise-level hard disk) is not the same as server-level hard disk, it does not necessarily have better performance than desktop level in terms of performance, for enterprise users, stability is more important, in long-term complex work, if the hard disk suddenly fails, it will bring irreparable losses to the enterprise.

Therefore, the general enterprise-level hard disk focuses on stability, while the server hard disk has higher requirements.

Of course, you can use it as long as you want. However, the more advanced thing is that SATA is an upgraded version of SCSI. So you have to look at the excuses.

If you used.

I think the speed of this server should be a blast.

The home computers we usually use are generally ordinary hard disks, but in recent years, the quality of hard disks has declined, which has caused many people to worry about data loss because of the hard disk, so it came into being enterprise-level hard disks, as the name suggests, relatively not easy to break, durable, and ...... long life

In fact, the real enterprise-level hard disk should be said to be server-level, that kind of is quite a cow, now the so-called enterprise-level launched on home computers, just understand it in this way, that is, ***, long life, not easy to break, in fact, this thing depends on the character, now the quality of the hard disk is too general, plus the software uses the hard disk more and more, the reading frequency is too high, the hard disk is too normal, it is not the same as buying an enterprise-level hard disk is not easy to break, it can only be said that it is more assured, If the SSD has not been popularized when you have a computer, then you will consider getting an enterprise-level hard disk to put relatively important data, just hang 2 hard disks, an ordinary enterprise, the important one in the enterprise.

Definition of an industrial-grade SSD.

Industrial-grade SSDs have two meanings, the first is to be used for industrial purposes, and the second is to meet industrial-grade standards and work reliably in harsh environments.

Industrial uses here are distinguished from those of consumer (personal), enterprise (commercial, data center) and military. Often, consumer and enterprise SSDs don't meet the requirements for reliable operation in industrial applications.

Industrial-grade requirements are usually used to work reliably under harsh working conditions, and are usually used in automobiles, automation, electric power, rail transit, and other occasions. These occasions usually encounter harsh working conditions, including: high temperature, low temperature, vibration, humidity, abnormal power failure, voltage instability, poor heat dissipation (no fan) and so on.

Reliable work, which means that there is no downtime under harsh working conditions. Because many equipment, once down, there will be very big harm and loss, such as transportation equipment is usually life-threatening, and power and other equipment failures will affect the lives of residents in a large area.

Many consumer-level manufacturers in the circle think that the gross profit of consumer-grade SSDs is low, and they look at the gross profit of industrial-grade SSDs, and turn consumer-grade products into consumer-grade products and change stickers, which is sold as industrial-grade SSDs, which is not shallow.

Fake industrial-grade SSDs.

Many consumer-level manufacturers in the circle think that the gross profit of consumer-grade SSDs is low, and they look at the gross profit of industrial-grade SSDs, and turn consumer-grade products into consumer-grade products and change stickers, which is sold as industrial-grade SSDs, which is not shallow.

In order to reduce costs, some machine factories take the initiative to embrace fake industrial-grade products, leaving hidden dangers to customers.

The difference between an industrial-grade SSD and a regular SSD.

Because of the harsh operating environment of industrial-grade SSDs, the quality of SSD products and the technical strength of manufacturers are very high.

Well-known brands on the market, including international and domestic first-line consumer brands, often only make consumer-grade products with low thresholds, but not industrial-grade products. To be a better industrial-grade manufacturer, on the contrary, the scale and reputation are not as good as consumer-level and enterprise-level manufacturers, because ordinary people do not contact and do not know, and only have a well-known brand in the circle.

The difference between an industrial SSD and a consumer SSD is:

Reliability: Must be able to work reliably, the cost of downtime is high.

Environmental reliability: Must be able to withstand harsh operating environments.

Stability: The operation is stable, and the parameters cannot fluctuate greatly.

Lifespan: The overall service life should reach 3-10 years.

Compatibility: There are many types of industrial motherboards, and the compatibility is poor, so they must be able to be compatible with a wide range of motherboards.

Enterprise disks: Highest performance, large cache, and fast speed.

Black disk: high performance, large cache, fast speed.

Enterprise-class hard disks usually refer to SCSI hard disks with high speed, hot swap, and stable operation for a long time. Enterprises that sell hard disks that have not been dismantled are generally SCSI, and they are usually SATA now.

The "black disk" represents Western Digital's high-performance hard drive. Some of the Western Digital brand drives have a black color block on the drive label that can be distinguished from other Western Digital hard drives, such as blue and green drives. This kind of "black jujube hard disk" has a faster read speed than ordinary products, and has better stability.

The control circuit of this type of 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.
