desertcart.com: 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 30TB HDD : Electronics

Review: A Fantastic Upgrade! Mediasonic Continues to Impress! - 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!
Review: Mediasonic 4 Bay USB 3.1 Gen-II/Type-C Review - Conclusions: Discussions of details and expansion of the conclusions follow, but it does get long. 1. The drives do spin down as expected. 2. The automatic functions (Power Sync and Auto Fan) do work, just not as well as they could. 3. The Auto Fan function did not shift into level 2 or level 3 soon enough to keep my drives from reaching undesirable temperatures (it didn’t shift to level 3 at all while in auto during my tests). The temps were kept within the drive manufacturer’s specs, but they were too hot for maximum drive life, IMO. 4. Leaving the fan on Level 3 rather than Auto did keep the drives within reasonable temperatures during my simple test. 5. Fan Levels 1 and 2 are quite quiet (Level 1 nearly silent) and Level 3, while louder than 2, is not intrusively loud (my unit is sitting next to me below my desk.) All of the above is based on my setup and my simple-to-do testing. I did NOT attempt a max load test, so do not overinterpret these results. Final Summary: I rated this device 4 out of 5, but with the caveat that the Auto Fan mode is NOT used, but rather keeping the fan set to manual at Level 3. Fan Auto might be useful for drives only accessed occasionally, such as backups or archives, but it is not useful for drives being actively used. My device is loaded as shown in photo #1. A total of 33TB and all bays occupied with 4 Western Digital drives of varying ages. My test technique was simple: I used the Auto Refresh function of CrystalDiskInfo 9.1.1 (CDI) to create activity on the drives and to report the individual drive temperatures. I recorded the temperature(s) every 10 minutes. All tests were run with the Power Sync On for the Mediasonic, which causes the device to shut down after inactivity as determined by the manufacturer. Test 1: Fan set to High. CDI set to auto refresh every 5 minutes while targeting a single drive (the one in Bay #2). I ran this test for one hour. More than adequate cooling for accessing one drive occasionally. See photo #2. Test 2: Fan set to Auto, otherwise the same as Test 1. In Auto mode, the fan remained at Level 1 for the entire test. Note that under the identical drive use scenario, this resulted in the drive temperature increasing by 2°C, but still more than adequate for accessing one drive occasionally. See photo #3. For Tests 3 and 4, I increased the drive activity by setting the CDI Auto Refresh to every 1 minute and to access all four drives at each refresh. This resulted in a significant increase in drive temperatures. Since temperatures were still rising after 1 hour, I ran these tests for 2 hours to determine where they would plateau. Test 3: Fan set to Auto, all drives refreshed every minute. The WD Red drives are spec’ed to have an operating temperature of up to 65°C, and the drives did stay well below that, but OTOH, I consider anything above 45° to be undesirable and at 50° or higher to be VERY undesirable. Therefore, I do not consider the cooling capability of this device with the fan set to auto to be adequate. Note that it never did shift to Level 3 fan speed. See photo #4. My final test was identical to Test 3, except the fan was taken off of auto and placed at Level 3. Test 4: Fan set to Level 3, all drives refreshed every minute. This test resulted in acceptable drive temperature control. Caveat: CDI Refresh every minute is hardly a drive stress test. See photo #5. I rated this device 4 out of 5, but with the caveat that the Auto Fan mode is NOT used, but rather kept set to manual at Level 3. Fan Auto might be useful for drives only accessed occasionally, such as backups or archives, but it is not useful for drives being actively used.

## Questions & Answers

**Q: has anyone tried 4tb hard drives in this unit? it states it supports it**
A: Yes:  WD Red 4TB, Linux, Fedora 20, GPT partition table, USB3, Intel NUC, the whole capacity of the drive shows up, no problems.Here's the smart data from the drive:=== START OF INFORMATION SECTION ===Model Family:     Western Digital Red (AF)Device Model:     WDC WD40EFRX-68WT0N0Serial Number:    WD-XXXXXXXXXXXXXXXXXXXXXXLU WWN Device Id: 5 0014ee 25e8d978cFirmware Version: 80.00A80User Capacity:    4,000,787,030,016 bytes 4.00 TBSector Sizes:     512 bytes logical, 4096 bytes physicalRotation Rate:    5400 rpmDevice is:        In smartctl database for details use: -P showATA Version is:   ACS-2 (minor revision not indicated)SATA Version is:  SATA 3.0, 6.0 Gb/s (current: 3.0 Gb/s)Local Time is:    Sat Aug 30 12:38:41 2014 PDTSMART support is: Available - device has SMART capability.SMART support is: EnabledFYI, I used "hdparm -J" to set the idle3 timeout to 120 seconds.  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.

### ⭐⭐⭐⭐⭐ Easy plug-n-play multi-drive enclosure
*by R***S on March 17, 2026*

Great enclosure and good chipset. Fan is not loud -- have this in a closet and is keeping my 2 drives under 45C. Plug-n-play with Linux. Really like the shutdown sync when the computer is off. Definitely would recommend.
