Bests & Worsts Reviews from Amazon

First off, let me begin by saying that I really like this enclosure, so much so that I bought two of them, a 4 bay and a 5 bay, both are usb 3.0 non raid variant. I love the aesthetic on it, simple, sleek, and clean, with no shiny black plastic, nice front grill and simple, straight forward installation. As you can see from the first two pictures, they even stack nicely on top of each other. With that said, I'm also writing this review in hopes that Yottamaster will see this and actually do something about the biggest weakness with their products. What is the biggest weakness (at least for me)? The airflow in these enclosures. I deal a lot with airflow at my job, since I design computer cases, where optimal airflow is important, but balancing both aesthetics and function is even more so. I understand that it's hard to achieve that balance, but if we were to choose between function over aesthetics, function will come first. And this is the biggest downfall for these products. The enclosures come with a single 80mm fan at the back that sucks in air through the front and exhausts out the back. Even the bigger 5 bay enclosure still comes with an 80mm fan, while it could actually fit a 92mm. Generally this would be alright in the 4 bay enclosure, but a couple of issues make this a bad fit. First, the fan's airflow is already weak as is to keep noise down. Second, Front and rear vents are so tight, airflow is severely choked. Barely any air can come in from the front, and barely any hot air can escape out the back. I found this out after installing all 4 bays and seeing in my HDD management software that the temps on all 4 HDDs were much higher than those inside my server's HDD enclosure. The situation is made even worse during warmer days, where the bottom and top HDDs would hit 45C (near critical temps) because air would not flow around these two drives. So I decided to take apart my enclosures, remove the measly 80mm fans, and externally install my own custom fans. As you can see in the 3rd picture, I attached a 92mm fan to the 4 bay enclosure, and 120mm fan to the 5 bay. This are high static pressure fans that push lots of air while doing so quietly. I set it up so that air is being pushed into the enclosures from the back and out the front. Due to how constricted airflow is, it's better to push air into the enclosures rather than venting it out the back since this will just create a partial vacuum inside the enclosure and actually increase temps. After doing these modifications, the temps are so much better and even across all HDDs. As mentioned earlier, I hope Yottamaster will try and put some effort into improving the airflow inside their enclosures, because currently, it's just a hot chamber when used in standard setups. To potential customers reading this, please make sure the enclosures are kept in a cool, well ventilated area. Never place them near a heater or other source of heat, and definitely don't let them try to cool themselves in summer (they can't).
