What is the difference between a fixed hard disk and an ordinary hard disk, and do you have to insta

To correct it, it is an SSD, the SSD has a fast read and write speed, which can improve the boot speed, but it is expensive, and the capacity of the HDD is large and cheap.

The boot speed and file transfer speed of the solid state drive are much faster than the mechanical hard disk, and it depends on the personal use to decide whether to install the solid state, but now the solid state and the mechanical disk are installed together is the mainstream.

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.

OK. Specify the boot sequence in the BIOS. The condition is that the computer has enough slots, power cables, and data interfaces to supply power. Installing the system in a solid state will improve the system running experience much better than that of an HDD.

When you boot into the BIOS settings, you can see the bootDevicePriority, which is the selection of the boot order of the hard disk and other devices. If you have two hard drives, you need to set the priority of the hard disks first.

The difference between a mechanical hard disk + an SSD or a separate SSD.

Hello Kiss is happy to answer this question for you. The difference between mechanical hard disk + solid state drive or separate solid state drive: If you feel that the capacity of the solid state is enough, a single solid state will do.

However, the solid state ** is high, and the large capacity is very expensive. The combination of small-capacity SSD and HDD is cost-effective, with both speed and capacity. The advantage of mechanical hard disk is that the technology is relatively mature, ** is not very expensive, if you say that the reading speed is slow, in fact, the reading speed will not be slow to Africa.

Although the solid state can reach several times the read speed of the mechanical hard disk, sometimes, some movies, documents, seeds, put in the solid state actually does not give you a big boost. However, it should be noted that the mechanical hard disk should not choose the turtle speed, 5400 rpm and 7200 rpm are actually two worlds. Therefore, some HDDs are particularly slow to read and write fragmented files, and the speed of SSDs is dozens of times better than that.

Comparison of advantages and disadvantages of mechanical hard disks and solid-state disks: 1. Shockproof and drop-resistant: mechanical hard disks are all disk-type, and data is stored in the disk sector.

The SSD is made of flash memory particles (i.e., memory, ***, USB flash drive and other storage media), so there are no mechanical parts inside the SSD SSD, so that even in the case of high-speed movement or even with flipping and tilting, it will not affect the normal use, and the possibility of data loss can be minimized in the event of collision and **. Compared with mechanical hard disks, solid hard has an absolute advantage. 2. Data storage speed:

The speed of the HDD is about 120MB s, the SSD speed of the SATA protocol is about 500MB s, the NVME protocol (the SSD speed of PCIe is about 1800MB S), the NVME protocol (the SSD speed of PCIe is about 3500MB Power consumption: The power consumption of SSDs is also lower than that of HDDs.

A computer can be equipped with only one of them, and the differences between hard disks and SSDs are as follows:

1. Speed, the transfer speed of the SSD can reach 500MB s, of which the read speed can reach 400-600MB per second, and the write speed can reach 200MB per second. The read speed limit of traditional hard disks cannot exceed 200MB/s, and the write speed is about 100MB/s. In the case of non-contiguous discrete data, the SSD can exhibit extremely fast read and write speeds.

However, the transmission speed of traditional mechanical hard disks is slow due to reasons such as head seeking.

2. Safety, SSDs do not have platters, so as long as their chips are not deformed by the shape extrusion, the data can be safely preserved. However, traditional hard disks do not have this advantage, once the platter and the head collide during high-speed rotation, or even unreasonable contact, it will cause damage to the platter and data loss.

3. Economical, under the same capacity, the SSD is 3-5 times higher than the traditional HDD at this stage, but with the advancement of Moore's Law, the density of the NAND flash memory chip of the SSD will become larger and larger, and the storage capacity will be higher and higher.

- -The read and write capabilities of the SSD are full of hard drives.

If you want to install a computer, of course, you can install only one of them, but this will happen.

1.Only the SSD is installed, and the capacity is not enough.

2.Only hard disks, no crazy reading and writing ability.

The recommended way to play games is SSD + hard drive. Put it in the SSD when you play, and throw it on the hard drive to save it if you don't play.

The hard disk is Western Digital, and the SSD is Samsung + OCZ + Puket.

Ordinary HDDs and SSDs have the same function, both are storage.

SSD seckill mechanical hard drive 100 streets is no joke.

It is recommended to prefer Samsung

The computer can only be installed with one of them, and the differences between the two are as follows:

1.SSDs are completely different from HDDs in terms of physical structure;

2.SSDs do not have mechanical parts like HDDs (such as heads, motors, etc.);

3.The part of the SSD that stores data is flash memory, which is a whole of many ordinary flash memory cards to store data;

4.Because SSDs are not limited by mechanical parts, they have higher read and write speeds than ordinary HDDs;

5.SSDs also have obvious shortcomings, that is, the flash size is limited by the number of reads and writes a few times, so it determines the life of the SSD, and now it has also launched an optimized technology, which greatly and effectively extends the life.

There are many brands such as Samsung, Western Digital, WestJet, etc
