Bests & Worsts Reviews from Amazon

I have the 7 port USB 3.0 connected to a USB 3.1 Gen 1 port. I have been able to connect two WD Passports one a 2TB and the other a 4TB. I transferred a 100GB mixed set of files from the 2TB to the 4TB While this transfer was going on at USB 3.0/Hard Drive speeds I also had a Samsung 850 Pro 1 TB in an HDE Clear USB 3.0 Gen 1 external case running a full crystaldiskmark6 benchmark test running. No hiccups at all the benchmark was as expected High 400 Read and Low 400 write. I have no idea how long this will last it appears well made for your basic 7 port USB 3.0. This is what I was looking for in a 7 port hub. So many would just lock up just having the two external hard drive hook up much less transferring 100GB of files. The built-in cable is heavy USB 3.1 Gen 2 type wire so be aware of that if you don't need to use for large data transfers I guess the only con would be the brightness of the blue LED's and they do bleed over to the port next to them but only on the side next to it so you can tell that the port is turned off. I will revisit this review should anything change in the next few months. 2020-05-03 my first on is still working great and I have purchased 2 more. I have never experienced a data transfer failure with any of the three. This is the one if you need to transfer a lot of data over 2 or more external hard drives at the same time. I'm not saying other companies haven't caught up with this unit but they hadn't when I bought the first one. I haven't felt the need to try any others.
