How do you measure the quality of an enterprise class hard drive? Which hard drive is better?

Speed, efficiency, stability and security are important indicators to measure the quality of enterprise hard disks, enterprise hard disks are faced with a huge amount of data throughput, storage is fast and efficient, in order to create higher value for enterprises, and stable and safe performance is the foundation of hard disks. In terms of product selection, it is no problem to choose a hard drive with a large manufacturer and a good reputation, such as Seagate enterprise hard drive products, EXOS Seagate enterprise hard drive and Nytro Seagate enterprise SSD products are enough to meet the above demanding requirements. The maximum storage space of the EXOS Seagate Enterprise Hard Drive supports 7x24 hours of stable operation to ensure stable performance in a variety of harsh environments, and the maximum storage space of the hard disk reaches an astonishing 12TB, which can help enterprises store massive amounts of information, and the hard disk has strong scalability, high-speed data transfer, full data protection, enhanced security policies and other latest technologies.

The so-called enterprise-class hard disk refers to the storage component that needs to have the ability to operate 24/7 and provide extremely high reliability and performance under high load. Seagate Galaxy Collection.

It is an enterprise-class hard drive with a maximum capacity of 16TB.

Measuring an enterprise-class hard drive requires knowing the specific application parameters: what size, what interface design, capacity, cache, and drive speed.

What are the differences between Seagate Enterprise Hard Drive series?

1. Different specifications: such as hard disk size, exclusive, magnetic density, number of disks and other factors.

Second, the design indicators are different: the working environment of the hard disk is different, which brings different manufacturing processes and testing standards.

3. Different reliability indicators: the warranty period is different, and whether the hard disk comes with data recovery services.

Enterprise-class hard drives wouldn't be better for home computers. The differences between the two are as follows:

1. Different working hours.

1. Enterprise-class hard disk: support 7*24 hours of work.

2. Ordinary hard disk: no need to support 7*24 hours of work.

Second, security is different.

1. Enterprise-level hard disk: Vertical magnetic recording technology and leading WIPE enhanced security technology ensure that the operation of hard disk is more secure and stable.

2. Ordinary hard disk: There is no special security technology design, and data will be lost in case of failure.

3. The transmission speed requirements are different.

1. Enterprise-class hard disk: Up to 6Gbps data transmission interface, 32nm enterprise-class SLC single-layer storage flash memory, and 2 million hours of trouble-free operation time all reflect the extremely high performance of the hard disk.

2. Ordinary hard disk: transfer speed 90-190MB per second. The read and write speed of a hard disk is mainly determined by the rotational speed.

The most important difference between enterprise-class hard drives and home-grade hard drives is that they are used differently, and the different uses determine their **. Enterprise-class hard disk has a higher speed (15000 rpm) faster read and write speed and higher stability, and enterprise-class hard disk is generally used to build RAID or server, which has higher requirements for data security and stability. And there are no requirements in terms of capacity.

If you install the enterprise-level hard disk into the home computer, there is no problem, but it will cause a waste of resources, and the price is very expensive, if the landlord wants to make the machine faster, then install two hard disks, a solid state drive, install the system, let the system in the solid state drive, the response speed and read and write speed will be improved a lot, and then install an ordinary hard disk is enough to put those games and movies and the like. Pure hand hitting, the watchtower owner adopts. Shanxi Shouyang Chengzhi Technology sincerely answers for you.

The read and write performance of enterprise hard disks of the same level is not much better than that of home hard disks, but enterprise hard disks often need to run 7x24 hours, so the emphasis is on stability, from design to manufacturing are stricter than home hard disks, and with some technologies that are conducive to stability and protection of data security, and stronger adaptability to high-load reads and writes, which are beyond the reach of home hard disks.

First, the read and write speed of enterprise-level hard disk is about 10,000 rpm, and its cache is also higher.

Second, the stability is higher than that of ordinary hard drives.

The read and write speed of enterprise-class hard drives is twice as high as that of ordinary ones, haven't you noticed that home computers use that is just a waste Enterprise hard disks are generally used for large servers.

Good stability. Read a few degrees faster. It is generally used in the computer room as a server. Home words. I recommend buying an SSD to work better.

1. To put it simply, the biggest difference between the two is "life", and the most basic standard for measuring the life of the hard disk is the "power-on time" of the hard disk. The lifespan of enterprise-class hard drives is more than twice that of ordinary civilian hard drives.

2. Storage type. The manufacturing process and materials of hard disk motors, magnetic heads, magnetic head arms and other components of enterprise-level hard disks are different from ordinary hard disks, especially motors, and the motors with high durability and long life are used to adapt to the state that may exist in the enterprise for 24*365 days without shutting down. Moreover, it is more resistant to "falls", and some also set multiple fuses for overload, so as not to damage the disk data in the event of a short circuit.

3. Energy efficiency. Because of the advent of SSDs, there are not many such energy-efficient enterprise drives. The standard hard disk speed is 7500 rpm and the cache is 8 32m, while the high-performance enterprise hard drive can reach 10000 rpm and 64m cache.

If you add RAID, the speed is not ordinarily fast. However, this kind of hard disk is threatened by the current SSD, because a normal SSD is already equivalent to the speed of two RAID0 high-speed hard disks.

Traditional mechanical hard disk, cheap and large capacity, read and write speed is generally divided into three kinds of conversion interfaces divided into IDE, SATA, SAS, SCSI (currently commonly used is SATA) on the market for home or ordinary business, all use SATA 7200 to turn hard disk, capacity, choose T, 2T, 3T, these are common.

The first-line manufacturers of mechanical hard disks, mainly the two major hard disk manufacturers Seagate (ST) and Western Digital (WD) Another emerging solid-state drive, composed of storage particles, is more than 2 times or faster than the traditional hard disk, but it is expensive and has a small capacity, 300 yuan can buy a 1000g traditional hard disk, and if you change to a solid state, you can only buy a 120g and add some money.

Generally, if you have economic conditions, you can buy an SSD, install the system and run the game, but the overall performance of the machine is not good, and it will not play the performance it should have.

Machinery is now monopolized by Western Digital and Seagate, and there is no gap in performance.

At present, the commonly used hard disk is divided into mechanical hard disk and solid state disk, mechanical hard disk read and write speed is slow, can not be bumped in the process of use, otherwise it is easy to damage the hard disk, but mechanical disk is cheap, mainly used for data storage. SSDs read and write at least 5 to 6 times faster than HDDs, and they are also not easily damaged. However, it is expensive and is generally used as a system disk to improve system performance.

The common brands of mechanical hard disks are Seagate, Western Digital, etc., and the better ones for solid-state drives are Intel Samsung, etc., all of which are good, depending on the specific needs of the individual to choose different hard disks.

At present, you mainly look at the computer hard disk, mechanical hard disk generally depends on the interface, speed and cache size, the larger the cache will be faster. Solid-state drives generally look at the chip, and there are mainly the following chips.

SLC = single-level cell, that is, 1bit cell, fast speed and long life, **super expensive (about 3 times more than MLC**), about 100,000 times erase life.

MLC = Multi-level cell, that is, 2bit cell, the speed is average, the life is average, **average, about 3000---10000 times erase life.

TLC = TRINARY-level CELL, that is, 3bit cell, there are also flash manufacturers called 8LC, slow speed and short life, **cheap, about 500 times erase life, no manufacturer can do 1000 times.

My suggestion is to choose the MLC of 64g because it has a longer lifespan and takes longer.

If the life of TLC above 128g is also acceptable.

It's too complicated to elaborate, and it's too inappropriate to copy and paste, so I'll briefly say it:

1. The power of the brand, it is wise to choose a big brand that consumers trust.

2.Hard disk technology, at present, is the best SSD solid state drive, power saving, silent, heat, the most important thing is fast speed, followed by hybrid hard disk, the most common is ordinary mechanical disk.

3, the number of revolutions and cache, mechanical disks are common 5400 and 7200 two, these two are the most used for notebooks and desktops, but with the progress of the times, notebook hard disks use 7200 rpm is also a lot, in addition to the cache, common 16MB 32MB high-end 64MB, etc., there are single and double disks.

Bad, the performance is good or bad, according to the upstairs statement is completely invisible.

Use HDTun to test it, and you can ask for it to be tested on the spot.

See how the curve is, how stable the read and write speed is, whether there are bad blocks, etc.
