I just started a new project recently, and then I bought this drive. Because the drive I bought at the beginning did not run very smoothly, I thought about changing to a new one. The reviews on the Internet were okay, so I bought it first to try it out. If it runs smoothly later, I will consider continuing to purchase it.

Its structure is very simple, very easy to operate, and it makes very little noise, so it won't disturb others when it's running. In addition, its energy consumption is very low as described, which saves me a lot of energy.
