Review: Works great. Even better after I installed a fan. - After testing, the digital electronics seem good. It does get hot with high power hard drives (e.g. 7200 RPM drives ) as there is really little thermal connectivity between the drive and the metal outer case as it is basically in a bubble of air. As in another review, there is a place (under the back sticker) to install a 30mm by 10mm thick 12v fan (has fan retention clips, fan holes and, a fan grate), so I installed a Delta fan. Unfortunately, there is no fan header on the enclosure's motherboard, so I hardwired the fan to the motherboard's incoming positive terminal (with a disconnect so you can take the closure completely apart easily) and hardwired (splice) to the power switch wire (switched negative). Temperature dropped way down (50+C --> 35C).
Review: Works-Fast and easy - Works as an esata drive for my video cameras. Fast and easy.

### ⭐⭐⭐⭐⭐ Works great. Even better after I installed a fan.
*by J***N on October 9, 2025*

After testing, the digital electronics seem good. It does get hot with high power hard drives (e.g. 7200 RPM drives ) as there is really little thermal connectivity between the drive and the metal outer case as it is basically in a bubble of air.

### ⭐⭐⭐⭐⭐ Works-Fast and easy
*by V***I on November 2, 2025*

Works as an esata drive for my video cameras. Fast and easy.

### ⭐⭐⭐⭐⭐ External for Camera System - Works Great
*by C***R on August 7, 2020*

Using this as an external expansion to my camera system (8x cameras running at 1440p). Works great, wish it had active cooling for when it gets hot, but to be honest (in normal conditions) this thing is great. Tool-less install was nice. The included stand is table though I keep the drive horizontal for my use case. Fellow IT Admins - If you're going to keep this in the server room, keep in mind that if your cooling solution goes down for some reason, this enclosure will easily get overheated similar to your servers. If you're redundant, not an issue, and definitely worth looking into for event testing and temporary use.
