Icy Dock Full Metal 4x 2.5-inch SAS/SATA HDD and SSD Cage in 1x 5.25-inch Bay

The product works very well and protects the hard drives when swapping them out. The drive cages offer great physical protection and hides the rear drive connectors preventing the possibility of electrostatic discharge from careless fingers. The locking mechanism is sturdy, precise and reliable. I assume you could swap in and out the drive many thousands of times without any problems. The only issue is the loud noise from the fans and high air throughput. The loud noise is extremely distracting in a home environment and will dominate. Also, the air throughput rate is large and will cause dust build up after a few months. The product is intended for an enterprise environment in a closed room. However, there is a workaround - you can easily disconnect and remove both fans to make this silent, and my SSDs have never gone above 35C even under heavy work load. This will obviously void your warranty and is done at your own risk, but after a year I couldn't take the noise anymore. Another option would be to replace the fans with silent ones purchased online.

Great design and features works well, and is REALLY loud. Like really loud. It is about 35% as loud as a hair dryer. Despite a military grade metal spec, I just can't get over the noise.

I would put five stars if the cooling fans weren't a bit too loud. I use it as a personal storage in my home desktop PC, and I find it a bit loud for that purpose. Otherwise really good quality design.
