HDD Enclosure Power

Power on the hard disk box, which is mainly aimed to select the USB interface HDD Enclosure friends. As the USB port of the maximum supply current of 500 mA, at some point, can not meet some of the 2.5-inch hard job requirements. If long-term drive to work at less than the rated current, then it is easy to make mistakes or even damaged. Its performance is often lost hard disk data format can not be completed when the display error, and on some computers (especially laptops) can not be used.

If so, you can choose to use an external power supply box or purchase a hard drive USB-PS2 interface, take the wire to solve, but some cold hard box with built-in power supply design, which can avoid the additional trouble of carrying an external transformer . If you are using an old laptop hard drive, but also pay attention to this problem, early models of notebook hard drive power consumption is often high, the use of current of 700 mA to 1200 mA are.

Mobile hard disk box material

Mobile hard disk box material is often overlooked when people are buying the place. Here we are talking about the materials used does not mean the shape of removable disk cartridge is design, whether to adopt the color covers, etc., but they use the material.

Current speed drive faster and faster, it also brings the heat dissipation problem. If you choose poor cooling capacity hard disk box, then the stable operation of the hard disk will have a big impact. Currently available low-cost removable disk cartridge commonly used plastic shell, the heat is less effective. Perhaps in a short time may be no problem for a long time if the exchange of information, then it may be stalled data transfer, data corruption, crashes and other problems.Currently the regular manufacturers of high quality mobile hard disk box, mostly using aluminum, and some even use aluminum-magnesium alloy as the shell material. Although this part of the price higher, but a good heat dissipation measures will allow you to work hard is more stable.

The shock of HDD Enclosure

Computer hard drives can be regarded as the most delicate part of the accessories, static and vibration are the two major killers. For as a "mobile database" mobile hard disk, the shock is the most important issue. If you do not design such as shock mounts buffer, once accidentally crash landing or otherwise, will often lead to data loss, will have a serious point of physical bad sectors, and even lead to damage hard disk completely, so I chose to pay attention to its removable disk cartridge is to provide seismic protection function.

HDD Enclosure Design

A removable disk cartridge is easy to use, the design is the key. In general, most of the mobile hard disk box has the following design:

Vents: If the shell is not a removable disk cartridge a good conductor of heat, the cooling holes should be around to help drive cooling. But for the 2.5-inch drives, because of their heat better than the control, this does not need to worry too much. And the hole too much, people will feel they are easier to attract dust.

Non-slip design: the mobile hard disk box housing designed non-slip pattern, or install non-slip plastic mat, etc., in order to increase friction between the shell and prevent HDD accidentally from the hand off.
