The function of the hard disk box is to physically protect a hard disk. At the same time, the mobile connection mode is used to realize the function of the mobile hard disk. Different from buying a mobile hard disk directly, it can reuse the idle hard disk at home or the hard disk replaced by the old computer.

Is it possible to use a hard disk by arbitrarily selecting a hard disk box? The hard disk is very delicate. What type of hard disk has a better anti-seismic and anti-falling effect? How to play hard disk performance? What are the key points to know in advance when choosing a suitable hard disk box? Next, let's discuss this problem together.

1. Confirm the type of hard disk first

The interface and size of the hard disk have different types, interfaces, and sizes. If it is not confirmed clearly, the hard disk purchased may not be applicable.

The type of hard disk is divided into solid-state (SSD) hard disk and mechanical hard disk from the carrier mode.

In terms of interface, SSD can be divided into PCI interface and SATA interface; Mechanical hard disk can be divided into SATA interface, PATA (IDE) interface, and SCIs and SAS interface (the latter two are mainly used for servers). Non PCI interface hard disk can be divided into 5.2 inches (obsolete and delisted), 3.5 inches, 2.5 inches, and 1.8 inches in size. At present, the mainstream hard disk is generally a SATA interface, the hard disk of a desktop computer is generally 3.5 inches, the hard disk of the notebook is generally 2.5 inches, and the netbook is generally 1.8 inches.

Generally, the hard disk box can be compatible with solid-state disks and mechanical hard disks. You need to look at a hard disk with the same interface and appropriate size. At present, most of the mainstream hard disk boxes are SATA interfaces, and there are 2.5-inch portable hard disk boxes and 3.5-inch hard disk boxes with larger storage capacity.

2. External power supply mobile hard disk is powered by computer USB interface, usb3 The interface current provided by 0 interfaces is 900 Ma, which is generally only enough for a 2.5-inch hard disk, while the power consumption of a 3.5-inch hard disk exceeds the range provided by USB. Therefore, the external power supply must be used to prevent insufficient current from affecting the use. It is safer to buy a hard disk box with an independent power interface.

3. The safety protective hard disk box needs a certain degree of firmness in protecting the hard disk and needs to have the effects of earthquake resistance and anti-skid. When purchasing a mobile hard disk box, you should know whether it has protective functions, such as rubber feet, whether it is covered with elastic materials, such as an anti-seismic sponge, which is stable and anti-seismic.

4. The sleep function will cause losses to the hard disk itself due to the long-term operation of the hard disk. The sleep function can make the hard disk enter the sleep state after some time without reading and writing tasks. Too short sleep time is easy to make the hard disk start frequently, and a reasonable sleep time can avoid frequent start.

5. Design of hard disk box a good hard disk box should have heat dissipation holes, indicator lights, data cable split design, etc. During the operation of electronic equipment, there will be heat release, especially in summer. The too high temperature will affect the performance of the hard disk. One side of the hard disk box should be covered with cooling holes to help the hard disk dissipate heat. Indicator light when there is data reading or storage on the hard disk, an indicator light will flash to remind users.
