Customers are mixed about the temperature of the hard drive enclosure. Some mention that the enclosure contains the heat well, making it susceptible to externally applied cooling. The plate has a thermal pad on it, which helps prevent throttling, but it does get very very hot. The enclosure also has heat transfer tape on the inside. However, some customers say that the cable is nice, but the enclosure gets a little warm after copying files and does Run Hot when transferring files.

Good enclosure, reaches advertised speed.

Installed a Silicon Power 1TB NVMe drive into the Acasis enclosure and ran a couple speed tests. Reaches 924 MB/s with the included USB-C cable, and 421 MB/s with the USB-A (USB 3) cable. Tried a different USB-C cable just to compare, and got the same result. Installation was easy, and the enclosure does get warm with continuous use but not really hot, so it must be helping to cool the drive. Overall, pleased with this product!

Great looking enclosure with sleep mode issues

Reviewed in the United States on February 29, 2024

Model: EC-6202Verified Purchase

Bought this to connect a 10tb hdd to a Beelink EQ mini pc that serves as a plex / file server. When it works, it works well. Fan is not too loud, the mechanical hard drive in it is louder when in use. Speed is more than enough for the drives in it, mechanical drive transfer speed is less than the usb 3.0 speed. All of this and it looks good doing it. The reason for the 3 stars is that it keeps going into sleep mode and not being accessible remotely or even locally. At times I have to turn it off and on or disconnect and connect it to the pc for it to be accessible again. I read on another review that there was a firmware update to fix this so I went to the manufacturer’s website and downloaded the firmware file. Followed the instructions but got 2 error messages: “Open Firmware File Error!!” and “Firmware File not support all chips”. After these error messages, the firmware flashing software opens but does not let me do anything other than “load INI” which gives me the same error messages when I choose the INI file, Refresh, Safe Remove and Close. Cannot change the Standby Timer or the firmware file. Windows 11 gives me no options to remedy this other than setting the usb to not allow it to turn off to save power, and this has done nothing to solve the issue. If I could get it to not go into sleep mode, I would give it 5 stars but with the issue, it is making me look for other options to get the file server working reliably.

An unexpectedly good RAID enclosure – With some caveats that earn a 4 star rating.

I purchased this enclosure to house 2 8TB HD drives which would be used for backups and external file storage. The unit is aluminum, except for the drive cart which is plastic. The 3.5″ HD drives fit nicely and were easy enough to install. The DIP switches are mounted on the drive cart, but the included instructions for the the DIP switch settings were not in English. Also, the DIP switch settings illustrations in the manual were incorrect. I found the ACASIS web site and located the English version of the manual. First problem solved Once the RAID enclosure was assembled and ready to go, I attached the USB cable to my computer. I powered up the enclosure and set the drives up. The first thing I noticed was the exhaust fan was very quiet. The second thing I noticed was the enclosure went to sleep after only a few minutes of non-use. The fan would stop (but not the drives) and the RAID enclosure would start to heat up. (Second problem). I tried adjusting the setting in the operating system to stop the enclosure for sleeping with no luck. I went back to the ACASIS web site and found an firmware update. The software that installed the firmware update also let me turn off sleep mode. Not I have a quiet running RAID enclosure that does not sleep but does power down when I turn off my computer. Unfortunately, the firmware update software is a Windows EXE file. Mac and Linux users may not be able to easily solve the sleep issue.

Can run VMs, and use as a bootable drive running OS at internal HD speeds.

Reviewed in the United States on December 24, 2018

Verified Purchase

Love it. My Samsung 970/960 EVO NVME drives fly with this. Only thing missing is a dedicated usb-c to usb-c. Instead bundled in a dongle. But quality is good, weight is good. The colour matches my MBP space grey which I do adore.

The read/write times are unreal. I copied a 200 GB VM of Windows 10 for VMware Fusion in a matter of seconds. Also was able to run OSes (win 10 and Ubuntu) as bootable drives from my MBP 2018. Felt like they were internal. Have never been able to run USB HD with amazing performance. It’s unreal, it kind of mitigates the lack of upgradeable Components in apples MacBooks when I’m running Win 10 in boot camp off a USB NVME drive like this. What a time to be alive!

Also I can run VMs off the drive directly. The boot and shutdown times are quick, and honestly can’t tell the difference from the internal HD, and apples m.2 2018 are scary fast.

Update: Still loving this drive. I actually formatted one of them as exFAT and was able to use pretty big Unity3D and Unreal Engine 4 Project(s) (each ~ 15-20 GB apiece, with 200-250k files total). Transfer times are crazy fast, and also I’m able to open the projects inside each respective editor with nearly no impact. Only one qualm I have is the thermal dissipation, they’re getting very hot to the touch, and I’m afraid if I keep going this rate for long periods of time, it’ll cut the life of the drive. Aside from that, I am still 1000% satisfied. For those out there thinking about buying a cheaper option, don’t. The case does make a different. and USB 3.1 has a 10GBps throughput, don’t settle for less or cheaper.

Here’s the screenshot of Blackmagic Disk Speedtest for this device with Samsung SM951 256GB. Test was run on an iMac Pro. Item looks sturdy, when runs speedtest might be warm. Installation was simple enough, no issues overall. Included wire is USB A(PC) – USB C(device), also included USB C-USB A converter, which doesn’t look convenient (simply 2 wires would be better).

Works but really poor performance

Reviewed in the United States on February 15, 2024

Model: EC-6202Verified Purchase

I’m using this with a 2016 Mac Pro connected to its usb 3.0 port. For reads and writes I’m getting 40 Mb per second throughput. This is horrendously bad performance. The device itself is kind of cheap, but works out of the box. The aluminum case is just the shell. All of the electronics are in a pull out plastic frame which holds the drives. If you go to the ACASIS web site, you can buy the device for $45.
