Mechanical hard disk is one of the types of computer memory, generally divided into two types: ordinary mechanical hard disk and enterprise-level mechanical hard disk. So, what is the difference between these two mechanical hard drives? Below, we will discuss this topic.
What is normal HDD suitable for?
normal HDD, often called desktop hard drive, desktop hard drive.
Generally speaking, the hard drives used in home computers are basically consumer grade, and only focus on running regular applications (Windows operating system, office applications, games, etc.), these applications sometimes only need software to read/write to the hard drive drive data.
normal HDD is mainly aimed at ordinary PC applications that do not need to be uninterrupted 7×24 hours, its drive is usually used for several hours a day, and most of the time is set to scheduled sleep/hibernate/off, during which time the hard drive is not used at all .
What scenarios are enterprise HDDs suitable for?
Enterprise HDDs have 7×24 uninterrupted operation capabilities, they not only rely on operating system and application load and runtime support, but also provide application and/or storage services to the network. This requires massive data storage, always available and reliable.
For example, an enterprise system can use four drives in a RAID 10 setup for the operating system and can use multiple drives configured in multiple RAID 5 or RAID 6 arrays to hold client data. Enterprise systems not only perform operating system and application tasks locally, but also support client requests 100% of the time.
Enterprise drives also typically contain internal mechanisms that allow for faster access and retrieval of data. These features include heavier actuator magnets, faster spindle speeds, denser magnetic media, and faster drive electronics with more cache and faster microprocessor speeds for hard drives.
Which one should I choose between enterprise HDD and normal HDD?
Compared with enterprise HDD, the price of normal HDD is close to the people, and its performance is not bad. Even some normal HDDs have better performance than enterprise HDD.
As a consumer, you’ll likely never see a difference even if you place the drives in the same system running side-by-side. Unless you plan to run a RAID configuration or plan to use your system on multiple users and/or data-intensive applications, a normal HDD will be all you really need.
If you plan to put your hard drive in a NAS RAID configuration or a local server that you plan to access remotely, then choosing an enterprise HDD drive is the right way to go.
For enterprise users, stability is more important. During long-term and complicated work, if the hard disk suddenly fails, it will bring irreparable losses to the enterprise.
In terms of speed, enterprise class is about the same as normal HDD. But compared with normal HDD, enterprise HDD has the advantages of reliability, long-term operation, and high MTBF (Mean Time Before Failure, mean time to failure).
The main difference between enterprise HDD and normal HDD is: lifespan
Enterprise-level must be durable, so the production process and materials of the hard disk motor, magnetic head, magnetic head arm and other components of enterprise HDD are different from ordinary hard disks, especially the motor, which adopts a high-durability and long-life motor, in order to adapt to the possibilities in the enterprise. There is a state of 24*365 days without shutdown. And it is more resistant to “dropping”. Some of them have multiple fuses for overloading, so as not to damage the disk data in the event of a short circuit. And although the hard disk is already a precision component, enterprise HDD has higher requirements for the precision parameters of the hard disk. The most basic criterion for measuring the life of a hard disk is the “power-on time” of the hard disk. The service life of enterprise HDD is more than 2 times that of ordinary civilian hard disks. In addition, enterprise HDD will not be equipped with too many new and cutting-edge technologies. They seek stability. All the technologies used have been tested by the market and have the longest trouble-free time.
In terms of enterprise hard drives, Exos and Nytro are their main products recently. Exos launched a 14TB hard drive for large capacity, and Nytro focuses on fast transmission. Readers can go to their official website for more information.
Unlike the Seagate desktop hard drive zoo, Seagate enterprise hard drives have become Exos, and the author’s favorite Cheetah and Savvio have completely become history. Now all enterprise-level HDDs belong to Exos and are divided into two series, Exos X and Exos E. , they are well distinguished:
“X” has always had a fascinating mystery, and as a symbol, the various symmetries of the letter itself are also very beautiful. Exos X actually represents Seagate’s helium hard drive:
From the above analysis, it can be seen that the difference between enterprise HDD and normal HDD lies in the hard disk capacity, price, read and write speed, reliability, durability and other aspects. Normal HDD is suitable for ordinary occasions such as personal computers, and enterprise HDD is suitable for special occasions such as large enterprises. The above two are very different, so you need to clarify your needs and choose the mechanical hard disk that suits you to better play its performance.
