In contrast, assembly of mobile hard disk, although the manufacturer can also install high-speed hard disk to your hard disk box, but due to the lack of synchronization control chip technology and can not interface with the hard drive to eliminate the bottleneck between the speed, so that assembly of a "high-speed mobile hard disk" can not truly reflect the advantages of high-speed hard drive, it is very easy because the interface with the speed difference between the hard disk, and there waiting for data transmission, data underrun issues.

反观组装移动硬盘，虽然其制造者也能将高速硬盘安装到硬盘盒中，但由于缺乏同步控制芯片技术而不能消除接口与硬盘速度之间的瓶颈，这样组装出来的"高速移动硬盘"并不能真正体现出高速硬盘的优势，倒是很容易因为接口与硬盘之间存在速度差，而出现数据传输等待、数据欠载等问题。
