What do SSDs do? Can it replace a hard disk?

Home computers don't usually have solid-state installed.

SSDs can be mounted with HDDs.

There is no clear limit, as long as it is not the kind of very old model, it can support solid-state drives, and the current upgrade of the notebook can meet the solid-state drive, but it is not recommended that you install It is said that the current notebook with solid-state is not very mature.

In addition, complain about it, if lz is not a professional fever entertainment or has special requirements for work, it is not recommended that you go to the solid state The two points I added are all light hosts are about 7000 Many friends around me, including enthusiasts who specialize in playing overclocking, have not installed the solid state only in terms of read and write speed will have an advantage over ordinary hard disks It is not that it can improve the actual performance of the computer For example, LZ plays GTA4 This game If your minimum configuration is not up to it, even if you press the solid state, you can't play If you can play Pressing the solid state also has no effect on the smoothness of the game So to put it The most intuitive effect of the solid state is to load the scene in the game Don't say anything else For example, Crossfire LZ must have understood that when entering the room game, the loading speed is obviously faster than that of a computer without solid-state and WOW is obviously faster when entering FB Nothing else has any effect The so-called high-end machine solid state is advertised by the manufacturer If LZ does not have a working need, it is not recommended to install it.

There are only solid-state drives on computers, and there are no mechanical hard disks, which can be used normally, and there is no difference from ordinary computers.

Why do some computers only have SSDs?

Because SSDs are fast, the user experience is greatly improved. As a result, some new computers are starting to only have SSDs instead of traditional HDDs. For example, ultrabooks, Apple books, etc. only have solid-state drives.

This will give users the impression that their computer is several times faster than a regular computer.

The performance of the solid-state drive in continuous read is several times that of the mechanical hard disk, and the speed of the solid-state disk on 4k small files is up to hundreds of times that of the mechanical hard disk, and when we use it in daily use, the continuous reading and writing situation only accounts for about 10%, and the system operation and some operations are processing small files, and the speed of the solid state in reading and writing small files is hundreds of times that of the machine, so the speed of the solid-state is much faster than that of the machine.

SSDs, like HDDs, are also a storage medium.

The main benefits of SSDs over HDDs:

1. The read and write speed has been greatly improved, and the common SATA3 interface consumer products can reach a 128K read and write rate of 400 500MB S, which is 3 4 times higher than that of mechanical hard disks, and the 4K rate (random access rate) is more than 10 times higher.

2. There are no mechanical parts, and it is not easy to be damaged. Traditional HDDs are very fragile when running, and if they are bumped, vibrated or dropped during operation, they may directly cause damage to the head or platter, causing permanent damage to the data.

3. No disk fragmentation, easy maintenance in the later stage.

But SSDs are not perfect, and there are currently the following main problems:

1. The cost is high, at present, there are three kinds of solid state drives: SLC, MLC and TLC, even if it is the cheapest TLC product, the unit capacity is still 6 7 times that of mechanical hard disk.

2. The life span is average, of course, the mid-to-high-end MLC particles and SLC particles are fine, but the low-end TLC particles have a shorter life.

Will the hard disk be eliminated, whether to buy an SSD or an HDD.

Solid-state drives are more suitable for system disks. SSDs are noiseless when in use, and there are no mechanical parts inside. Flash memory particles are used, so there is little chance of data loss due to collisions and vibrations.

And the read speed of the SSD can reach 3500MB s, and the power consumption and heat generation are lower than that of the HDD. Then the disadvantage is that once the data is lost, the difficulty of recovering it is greater than that of the mechanical hard disk, and it is slightly more expensive than the mechanical hard disk.

SSDs are identical to ordinary HDDs in terms of interface specifications and definitions, functions and usage methods, and are basically the same as HDDs in terms of product shape and size (the size and shape of SSDs in the emerging form are completely different from SATA HDDs).

Because the technology of solid-state drives is different from that of traditional hard disks, many new memory manufacturers have emerged. Manufacturers only need to buy NAND chips, then configure the appropriate control chip, write the main controller**, and make the SSD.

Storing data. Solid-state drives have the characteristics of fast read/write, light weight, low energy consumption and small size that traditional mechanical hard disks do not have, and their disadvantages are also obvious.

SSDs are identical to HDDs in terms of interface specifications and definitions, functions and usage methods, and are also completely consistent with HDDs in terms of product shape and size. It is widely used in military, vehicle, industrial control, ** monitoring, network monitoring, network terminals, electric power, medical, aviation, navigation equipment and many other fields.

Hard disks are used to store data.

A hard disk is a computer's external memory that is used to store data that will be read into memory.

Including the operating system is also installed on the hard disk.

SSDs and HDDs are both hard drives. It's just that SSDs are faster!

How should SSDs and HDDs be chosen? It has always been a big problem that bothers people, in fact, the choice between the two is not a particularly difficult thing, as long as you figure out the advantages and disadvantages between each hard drive, you can choose.

Mechanical hard disk (HDD) is a traditional ordinary hard disk, which is mainly composed of: platter, head, platter shaft and control motor, head controller, data converter, interface, cache and other parts. Solid state drives are hard drives made with an array of solid-state electronic memory chips.

The read speed of mechanical hard disk cannot exceed 200 M/s, and the write speed is difficult to exceed 100M/s. SSDs have great advantages in transfer speed, up to 500M/s, of which the read speed can reach 400-600M/s, and the write speed can also be as high as 200M/s. It only takes a few seconds to get a 1GB file, so it's better to choose an SSD for users who want to read or process large files for speed.

Solid-state drives have a great advantage in speed, but due to the higher cost, solid-state drives are generally 2-3 times that of mechanical hard disks, but with the continuous development of Moore's law, the density of solid-state disk NAND flash memory chips will become larger and larger, and the storage capacity will be higher and higher, and the future will be lower and lower, and it is foreseeable that solid-state drives will replace traditional mechanical hard disks. Moreover, SSDs have an advantage in size and quality, and are also better shockproof, making them more portable for users who often travel with computers.

Therefore, it is actually very easy to see what aspects of performance you particularly need, and then choose what kind of hard disk you want according to your needs.

Summary. Solid-state drives (SSDs) and hard disk drives (HDDs) are very different in terms of storage methods and usage characteristics. SSDs use pure electronic storage, which is faster, consumes less power, and has high stability, whereas HDDs use mechanical rotating storage, which is comparatively slower and consumes more power.

Therefore, whether or not you need an HDD depends mainly on your usage needs and budget. If you're concerned about the speed and response time of your computer system, then SSDs are a very good choice because they can provide faster data reads and writes than HDDs, making the operating system boot up and applications load faster. In addition, SSDs are also more reliable because they have no mechanical moving parts and are not easily damaged.

However, SSDs are relatively high and have a relatively small storage capacity, making HDDs still an affordable option if you need a lot of storage space. You can choose to install the operating system and frequently used applications on the SSD, and store other data files and ** files on the HDD. This allows for a balance of speed and storage capacity, improving the performance of the entire system.

You can choose to install the Hoku operating system and common applications on the SSD, and store other data files and ** files on the hard disk. This allows for a balance of speed and storage capacity, improving the performance of the entire system.

So dear, if you don't have higher requirements, you don't need a mechanical hard disk with an SSD.
