Review on StarTech Computer Accessories & Peripherals for Computer Cable Adapters by Eli Cooper

I have four working external drives. Two HHD RAIDs and two SSDs. I separated them from the ports I've been using for months and plugged all four into a hub. I ran speed tests on two drives and the speed test app reported errors. Meanwhile, background processes have been written to two RAIDs. Then they reported the bug. I turned off my computer and reconnected four drives to the ports they were previously connected to and now all four drives are corrupted and unusable. Now I need to copy over 8GB of data and test if it can be recovered without corruption. ATTENTION TO THE BUYER. (I've been building computers since the 80's. I'm good with hardware.)
