Review: Quick, easy, and effective - Replaced an old Proliant Micro server (NxxL 1st gen) that would keep losing cheap Flex ATX power supplies every year or two. Was looking for a replacement that also had 4 bays, low power consumption and no need for RAID to drive a headless Linux media NAS with several Docker apps installed. Paired it with an older EliteDesk USFF which was already doing other related duties. Fit and finish is fantastic, better than expected. It's still slightly on the cheesy side and the lights are excessively bright (I'd recommend some black tinting tape). Drive installation was very easy. Much smaller than I expected. Options are dead simple and you basically know how to operate it from the small labelled picture on the folded quick start guide. Fans are quiet, even on max, although I'm not yet sure how well they are cooling the drives. Auto-sleep function also works well (I wouldn't use the auto-off as it fully powers down and doesn't power back up). I have been using it in USB mode since I am using a tiny, slim desktop with no expansion options and it has worked well so far. Drives were detected right away. I have not yet gained S.M.A.R.T. visibility but hope to at least get a basic "healthy" status. It's not technically supported (Linux that is) so not something I'd ding it for since I can read :-) Really nice unit so far. If all goes well, may pickup the 8-bay version for my backups. MAY 2025 UPDATE - Still running strong, no new fan noise/vibration, good disk health, never once had to reset due to disk communication loss. Have had power loss in my home where I had to manually turn the enclosure back on, but basically non-issue. Maybe people have problems with the USB 3.2 version and/or RAID? Was happy to see Mediasonic back in stock so immediately ordered the 8-bay eSATA/USB 3.0 when it became available. Both connection options exceed the network connectivity to the attached PC so no need for 3.2
Review: Bright Lights, Good Value, - I add my voice to the small group who think that a drive activity indicator does not need to be bright enough to read the fine print in a EULA. There is a six-inch piece of black electrical tape in the future of my ProBox. The unit came with a map-fold sheet labeled 'Quick Installation Guide' on the front, and a 'Thank You' note. Both had different web links that offered a manual. I could not make either of these links work. When I came to write this review I discovered a bullet in the 'About This Item' section that offered a link to a manual. After scrolling up and down the page for a while I found the link rendered in the smallest type, just where the bullet said it would be. This link worked for me and led to a PDF version of the same map-fold sheet that came with the unit. In spite of what it says on the front, that sheet apparently is the manual. As such it offers pretty good graphics with mediocre and obviously translated accompanying text. The most glaring fault is the total absence of technical specifications. It does have enough information to get the unit set up and running. One of the things you may need the manual for is how to get the unit open. It features a unique set of molded plastic latches, one for the hinged front panel (which comes off when you open it) and a different style set-of-two to remove the plate that holds the drives in their bays. These appear fairly sturdy but I wonder about their longevity in the warm environment. Fortunately they don't appear to be necessary for the operation of the unit. As a person with experience using external drive enclosures I found the setup reasonably easy. The unit and all drives were immediately recognized by my eSATA I/O card and have run seamlessly for about a week. I am not a fan of power bricks and this one looks particularly vexing because it uses a right-angle connector to plug into the side of the unit at the back. This means you can't put that side up against anything or have two units side-by-side without a gap. I read some comments about overheating. I have not experienced this. I loaded the ProBox with four 7200RPM terabyte-sized drives and set it to a multi-hour backup task. I never saw temperatures in excess of 41°C. It didn't even ramp up the automatic fans. In any case there is a manual fan control that can turn them up to a dull roar. I used eSATA to hook the ProBox to my MacPro and discovered I had to disable the automatic shut-off feature because it would not wake when the computer came out of sleep mode. This might work better with a newer computer or over USB. This isn't a big power-waster because the computer system spins down the drives in sleep mode. I found the operation of some of the front panel push buttons less than intuitive. To change the interface mode you must hold the button for several seconds. To power the unit on you push and release the power button. To power it off you must push and hold the power button. Bottom Line: In spite of some quirky design choices, overall this appears to be a reasonably well constructed unit at an attractive price. I liked the first one well enough I ordered another.

## Questions & Answers

**Q: Amazon has 2 boxes from this manufacturer. 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.

### ⭐⭐⭐⭐⭐ Exactly what I wanted!
*by F***T on August 16, 2025*

This mediasonic probox 4 bay enclosure is exactly what I needed! I have two 14TB Seagate exos X16 enterprise HDDs in it hooked up to my PC using eSATA VIA a 10Gtek eSATA to PCie card (also purchased here on Amazon) and it works great! I did install and update the 10Gtek driver before I hooked the mediasonic enclosure to my computer. The drivers for the 10Gtek card is no where to be found if you search for 10Gtek drives BUT this card is based on the ASMedia ASM1061 chip so I went to ASMedias websites and found the driver there. Once that driver was installed, I hooked the mediasonic probox enclosure up and turned it on and windows 11 recognized both my drives with no issues! For me, It was easy to open and install the drives. Yes, as mentioned by others here, the front blue lights are bright when its on but it doesn't bother me because I have it under my desk where its not really visible and plus I don't leave it on all the time. I only turn it on when I have to make a backup of something. I have the fan on high because fan noise doesn't bother me, plus all I'll about keeping components as cool as possible. On high, yes it is very noticeable but on medium, it is barely audible to me from about 3 feet away where it sits. And speaking cooling, it does a good job of keeping my drives cool. At Idle, according to crystaldiskinfo, they sit at about 34c-36c. I copied 4 TB of data to both drives and even copying for 10+ hours straight, neither drive got above 45C. I should mention I copied data to one drive at a time and not simultaneously so I can't speak to how the the temps would be doing more then one at time. Copy time was as I expected for 7200RPM drives in the range of 60MB/s to 220MB/s with an average of about 80MBs-110MB/s. I had a lot of very small files in the transfer so speeds where up and down. I am also using a 6FT eSATA cable and no issues with that length. I have not used USB nor do I plan on it so I can't speak to how that performs but I'm sure its good. I had read that eSATA can be a little more reliable and stable when transferring large amounts of data at a time so since I had planned on moving 4+ TB at a time, I specially went with eSATA. So far, I'm more then pleased with purchasing the mediasonic probox enclosure and will definitely purchase another one if I ever need another in the future!
