The big drawback: In the product description mentions that connected SATA devices are powered using the included AC adapter. It is not clear that no operation is possible without power supply - and that's not self-evident, since a USB itself is 900 mA available 3.0 connection. That's enough loose for standard 2.5 "hard drives (my test SSD draws a maximum of 500 mA) and for the control electronics is still a good reserve. Not for nothing, there are external 2.5" HD enclosure with USB 3.0 port that do not require power supply. Of course, a supplied AC adapter makes perfect sense if, for example power-hungry 3.5 "devices to be operated. But the exclusive operation via the PSU is an unnecessary and unreasonable restriction of the use possibilities. Why should I carry around a power supply with me at all when I go eg wants to connect flexibly only a 2.5 "HD? The power supply has more volume and more massive than the HD itself!
Conclusion: Suitable for stationary operation, nothing on the go. No more flexible replacement for a 2.5 "USB 3.0 hard drive enclosure.
