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.

The HFR2-SU3S2 ProRaid ,, and the HFR2-SU3S2 drive enclosure. WHATS THE DIFFERENCE?** A: There are two versions of the HFR2-SU3S2: ProRaid and ProBox. The former supports RAID in hardware while the latter does not. The ProRaid supports pretty much every form of RAID I can think of, including 0 (two types), 1, 3, 5, and 10. However, the throughput in RAID mode is 3 Gbps while non-RAID can run as fast as (if your disks can keep up) 6 Gbps. Some people prefer to have their operating system implement RAID, some prefer hardware RAID. With the HFR2-SU3S2, you can buy the product that meets your needs. **Q: Anyone has tested this unit with 6 TB hard drives?** A: I'm running 4 X 8TB drives with no problems. **Q: Can this device be hooked up directly to a Router instead of a PC?** A: No This is not a NAS (Network Attached Storage) device, unless your router has a USB Port for external storage this will not work. **Q: What are the differences between the hf2-su31c and hf7-su31c models ? and is there proraid version of this ? (one that supports raid).** A: Hi, The only difference is the design of the exterior case. The main board and chipset are the same. This is NOT a raid version. The Raid version will be available in two month. ## 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.

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 PROBOX 4 Bay 3.5” SATA Hard Drive Enclosure – USB 3.0 eSATA Support 24TB HDD (HF2-SU3S3) - StarTech.com 2 Port PCI Express SATA 6 Gbps eSATA Controller Card - Dual Port PCIe SATA III Card - 2 Int/2 Ext - SATA III 6Gbps (PEXESAT322I) - StarTech.com Shielded External eSATA Cable - eSATA cable - Serial ATA 150 - eSATA (M) to eSATA (M) (3 ft) - black (ESATA3) --- ## 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.hr/products/423716365-mediasonic-usb-3-2-4-bay-3-5-sata-hard](https://www.desertcart.hr/products/423716365-mediasonic-usb-3-2-4-bay-3-5-sata-hard) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-28*
