Review on ORICO 4 Bay HDD RAID Enclosure USB External Hard Drive Enclosure Aluminum Magnetic SATA III Disk Storage Case Tool-Free for 2.5/3.5 SSD HDD, 64TB (4x16TB) Support, Ideal for Data Backup, NAS Expansion - NS400RU3 by Steven Brouillard

I bought this case to replace a two drive RAID array that my system was consistently unable to find. I thought the spikes were damaged but when I inserted them into this block they immediately popped out. I added two more drives and created an 8TB RAID 10 block. Since this device has a fan for cooling, this can be annoying. Unfortunately, when I turn off the computer, the fan keeps running and I have to turn off the device manually. In addition, the blue plastic shell inside the lid can be removed for better air circulation through the side ventilation openings.
