Mediasonic USB 3.1 4 Bay 3.5' SATA Hard Drive Enclosure - USB 3.1 Gen 2 10Gbps Type C/USB-C (HF7-SU31C)

I read through a lot of reviews about this enclosure, and there were a solid number of them that had negative experiences with the cooling aspects of this device.Reading deeper, I discovered a couple of things that stood out in some of the negative reviews; 1) not all of the drives that were being used were of solid quality, not saying that’s the entire issue they were having, but SMART failures on cheaper less reliable HDDs are not uncommon and may not have had anything to do with the drive itself and 2) the temperatures people were reporting as high were….well within normal operating temps for drives. In fact, HDDs prefer to be on the warm size, 40-42c is totally fine. Cold drives can actually end up with critical failures with the bearings and other parts. During heavy operations, drive temps climb, and it’s not uncommon to see 52 or so C (about 125f). The key is watching for sudden inconsistent spikes in the temps. If the temperatures are a steady flat line, and the fans are spinning, you’re doing fine.I gave the enclosure a thorough inspection before actually plugging it in for use; the ventilation is more than adequate. The vents along the bottom of the door and the rear fan are plenty.I’m using this enclosure as expanded storage for my server. Currently it’s just housing a single WD Blue 12tb. I moved several TBs of files onto the drive and during all of that writing, the auto fan never went above the first fan speed setting, the drive temps were stable and well within operating norms, and in fact, the enclosure itself never even got warm.It’s certainly possible that people got faulty units, or maybe there wasn’t the added vents on the front door early on, not sure.What I can say is that the INITIAL operation and inspection of this enclosure is fine. Time will tell if it holds up, though for me the drive and the enclosure are merely serving media and not doing constant heavy read/writes. But as of now, I think it will suit my needs just fine.

I got this to declutter the shelf where my home media server lives. Instead of having 4 USB drives sitting on the shelf I now have this one box connected via USB-C to a mini-PC with no internal storage beyond an NVMe SSD.It's very quick and works perfectly well but does NOT support hardware RAID. One could make a software RAID using Windows 10/11 Professional, note that the specs state this enclosure does not work with Linux. I have not tested it with Linux.The sync button is interesting. With sync turned on the enclosure powers up and down with the computer to which it is attached but will not recover from a power failure, that requires a human intervention to push the power button on the front.I cannot really fault this enclosure, for the price it is a great deal.

Good for the price...I suppose

Very easy to install, works well and reliable as well as very quiet

Only had it 2 days but so far very good!I bought this to replace an Orico 5 bay box which had several faults and was returned for refund and that was actually bought to replace my QNAP 4 bay NAS which has failed after 4 years. Decided I did not really need a NAS as only used it for backups and local storage not as a server.This one seems to work as it should and has the added advantage of the "sync" function to turn on and off with your PC which seems to work OK and I like the provision of being able to control the fan speeds - either auto or manually - which I have tested and with reasonably heavy use I have found that speed 2 seems to keep the drives under 45C and is virtually silent - speed 3 will lower the temps quite a bit but is audible - not a nasty noise so quite usable unless the box is right next to you.Disk installation is not tool-less as you have to fit plastic handles to one end of each disk and then clip a metal retaining plate over all the bays which lightly clamps against the rubber buffers on the handles - seemed a bit of a fuss but it definitely keeps the drives securely in place and is easy once you have fitted it a couple of times.The only slight annoyance is you cannot "safely remove" all the drives in one go like I could on the Orico? Each is listed as a USB 3.1 SATA bridge and "safely removed" individually in my Win 10? It also does not seem to spin down any of the drives whilst it is connected to the PC?Main concern - it only came with a US style mains lead! For the moment I have used the one from my redundant QNAP NAS for now but come on Amazon - I know it came from Amazon US via an Amazon UK order so why is it not supplied with the correct mains lead for the destination market? Many well known suppliers in China and Singapore can get it right!Update: I have been through a very involved and time consuming process of trying to get Amazon to send me a complimentary UK mains lead so I can keep the product and make it actually conform to the market they have sold it in. After all it's basically only a fiver or so!"Chat" was useless so got them to telephone me - not able to replace parts only the whole item or a refund! When I explained I was already returning the Orico as faulty and this Mediasonic actually works but it was sold with the wrong mains lead - surely it would be far more cost effective for Amazon just to send me a suitable mains lead, FOC, rather than having the cost of the return carriage and them sorting and putting it in their "used but no cables" type warehouse deals? Obviously a replacement would have the same problem!I was told they would "escalate" to a higher level and if I would like to add a suitable lead to my basket they would sort it out.I added the cable to my basket - it is still sitting there. The result I got several confusing help emails from CS throughout the evening plus an SMS then a phone call just before midnight! The caller had a very heavy non English accent and talked so fast I could barely understand anything - he sent me a code which I read back and then he wanted another confirmation to another email - at this point I started to be suspicious so I ended the call.Very disappointing and just confirms that like many others, Amazon has joined the ranks of not really caring about their customers or any problems that their mistakes have caused. We have your money, don't bother us, return it if their is a problem seems to be their answer to everything!"Customer centric" - hardly!
