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 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.

I've been a loyal Mediasonic customer for years, having owned an older version of their 4-bay hard drive enclosure, which I absolutely loved. It was a workhorse, reliable, and served my storage needs perfectly. When I saw the Mediasonic USB 3.2 4 Bay 3.5” SATA Hard Drive Enclosure DAS (HF7-SU31C) with USB 3.2 Gen 2 10Gbps Type C, I knew it was time for an upgrade, and I'm so glad I did! This new enclosure takes everything I appreciated about the older model and elevates it. The USB 3.2 Gen 2 10Gbps Type C connection is a game-changer. Data transfer speeds are incredibly fast, making backups and large file transfers feel instantaneous. I'm currently using it with 24TB HDDs, and it handles them flawlessly. Setup was a breeze, just like with my previous Mediasonic enclosure. The build quality is solid, and the design is sleek and efficient. It runs quietly, and the drives stay cool even under heavy use. If you're looking for a reliable, high-speed, and well-built external hard drive enclosure, look no further. Whether you're upgrading like me or buying your first, the Mediasonic HF7-SU31C is an outstanding choice. Highly recommend!

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!
