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. Review: Works as Advertised - Been using this guy for about a year now. It's solid and supports all the stuff they say it does. I'm using a dell desktop for server with Debian, getting 10Gb transfer speeds. ZFS is rock solid, zero errors ever. Only thing I wish for is it auto powered on after power loss. Cooling is not very good. I bought a $10 external fan and keep the door open all the time. The noise of the fan at high speed is awful so I put it on level 2 (of 3) in this configuration. Just fine for my closet home server on a budget. It's also a bit rickety without making me nervous, just strong enough I guess. It's not all metal like some. But it has it where it counts as Han Solo has said. ## Features - Newly revised front door with Air In-Take feature. Chipset VIALabs VL820 + VL716.

It did not brick the drive and appeared to work; however, I will express the strong caveat that is a dangerous operation.# hdparm -J /dev/sdddev/sdd: wdidle3 = 120 secs (or 13.2 secs for older drives) **Q: Is there any way to make these units turn on after a power fail w/o pressing the button? I tried the 3 sync modes and regardless of what the attached server does it seems I have to manually press the power on button to get these to start responding after a power failure (USB-3).** A: A comment to Abi and Phillip on chaining UPS units: I think the issue is total current draw, and usually if someone is adding another UPS, they plan to draw that much more current through the system, and that would indeed be bad. In general, it is good advice not to chain UPS or surge power strips, given how people normally just keeping plugging things in until all outlets are occupied. But... if Abi is disciplined and only plugs the one thing into that chained UPS that otherwise would occupy a plug on the first UPS, I'm not seeing the problem. Maybe Abi should tape over or toddler-plug the remaining outlets on the chained UPS as a reminder to avoid dangerous current draw situations? The total load on the first UPS then is almost unchanged (modulo the power overhead of the chained UPS itself), and if there is some reserve capacity on the first UPS, that shouldn't be a problem. Is there some other consideration I am missing here? **Q: If I install 4 x 4TB drives on this unit and connect it to my computer, I see 4 new USB hdds in my PC or just one big drive?.** A: If you just install the drives and power on, they will show up as separate drives. If you're using eSata, you can setup a RAID configration. (I use 3-3tb drives in raid 5) You can also use Windows Storage spaces to 'unite' the individual drives into one drive. Raid is faster though. **Q: has anyone tried putting a 2.5" 1 TB HDD in this thing? Do I have to use an 3.5" adapter or can I just plug in the 2.5" HDD?** A: Note: A Normal adapter/brace will not work that you would used for mounting a 2.5 in a PC case. The connections for the power and data transfer are fixed solid to the board in the back of the case. A normal adapter will leave the 2.5 drive well short of the connections and you will need to run cabled for the power and data, very very short cables. Additionally, the metal plate that functions to hold the drives in place will not fit snugly with the 2.5 drive adapter meaning it will float around in there just a little to make some noise. Due to these reasons I would suggest only using it for 3.5 drives as they fit perfectly in the drive bays. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Cools just fine *by D***T on May 13, 2026* 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.

But it has it where it counts as Han Solo has said. ### ⭐⭐⭐⭐ Either break off the front door or keep it open to prevent drive overheating. *by J***E on June 18, 2018* Good: * This unit does work on USB 3.1 and has really fantastic transfer rates. * The case is beautiful and looks very modern * The drive trays fit snugly enough where there is not any noticeable rattle or noise from the hard disks Bad: * The makers clearly told the engineers to get lost and opted to make this pretty over functional. There is a fan and an air outlet in the back, but there is NO venting at all in the front to let air in to flow over the drives. I mean, come on Mediasonic!. Radiant cooling only works when air can get in, pass over the drives, and the exit the case. That process cannot occur when there is no air inlet. * Two drives quickly overheated in this case with the fan set to "Auto". The case was in an air-conditioned room at about 75 F. The drives both reached over 110F and trigged SMART monitoring failures. * The only solution to the airflow issue is to open the front door or break it off. In fact, I have popped my door open with a CD jewel case. * With the front door open and the fan turned up manually, it does a great job of cooling the drives. Unfortunately, the front door open also makes the drives and fan noise pretty loud. In summary, it works great and does everything it promises, but only when the front door is kept open. I plan to take the door off and cut space for a screw-on fan grill and screen. Though, if I need any more of these, I will spend more and get a better designed product, such as the ORICO Aluminum 4 Bay that is not that much more. Alternatively, the older Mediasonic design is much better because it actually has air flow inlets in the front. Update: After use for a while of use, I can say it does a good job of keeping the drives cool with the door open. Most critically, the USB 3.1 controller seems stable and works well in Linux. I tested both kernels 4.9.x (Debian Stretch) and 4.16.x (Debian Buster) on an AMD X470 chipset. So, I am raising my rating to 4 stars, since it is functional, even if they screwed up by not putting a vent in the door. ## Frequently Bought Together - Mediasonic USB 3.2 4 Bay 3.5” SATA Hard Drive Enclosure DAS – USB 3.2 Gen 2 10Gbps Type C | USB-C (HF7-SU31C) Support 24TB HDD - Amazon Basics USB-C to USB-A 3.1 Gen 2 Adapter Charger Cable, Fast Charger, 10Gbps High-Speed, USB-IF Certified, Compatible with iPhone 16/15, iPad, Tablets, Laptops, 3 Foot, Black - Mediasonic SSD Mounting Bracket for 2.5-inch to 3.5-inch Hard Disk Drive (HDB-G1) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/59108166-usb-3-2-4-bay-3-5-sata-hard-drive](https://www.desertcart.be/products/59108166-usb-3-2-4-bay-3-5-sata-hard-drive) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-08-28*
