If you are constantly worried about losing important files due to an unexpected hard disk failure, then frequent backups are essential. For small businesses or individual users, storing all your data on a single hard disk is a potential disaster. In the event of a failure, not only do you need to make a huge effort to recover the data, but you also need to spend a lot of money. Moving large volumes of data from one hard disk to another can also be a time-consuming task.

However, hardware backup may be a more convenient option. In this regard, the Unestech ST7221 2.5″ + 3.5″ Dual bay hdd mobile rack is worthy of your trust. It offers space to install both 2.5″ and 3.5″ hard drives and SSDs at the same time, tool-less and screw-less hot-swappable function, independent power switch design, and tool-less design for easy installation of your hard drives without any screws after installing them in your computer. Simply install the hard drive into the slot and turn on the switch, the body is designed to utilize a 5.25" drive bay to fit a 2.5" and 3.5" hard drive at the same time. Make the most of your space and save a lot of time replacing hard drives.

As an excellent alternative to external hard disk holders, they are often used to back up data. The similarity between them lies in their functionality, but what are the differences? The biggest difference is the speed of file transfer. Traditional external hard disk holders have a theoretical transfer speed of 5Gb/s through the USB 3.0 interface, however, in practice, it may seem a bit slow. The ST7221, on the other hand, utilizes a SATA3 6Gb/s transfer method, making backup of files much shorter.

The tool-less mobile rack design saves the time of installing a hard disk and allows you to back up data from another hard disk. It takes only a few moments to install the product in the computer, and then you don't need to spend time on swapping out hard disks, and if the hard disk fails and needs to be repaired, it takes only a few seconds to remove the hard disk, which is convenient and fast!
