4.0 de un máximo de 5 estrellas The best 8-bay JBOD enclosure I've ever used... but still not perfect 24 de agosto de 2015
Por Amazon Customer - Publicado en Amazon.com
Compra verificada
I've tried many multi-drive JBOD products and none of them have ever really worked as advertised. This one actually comes pretty close to being "perfect" for me.

Unlike the StarTech.com USB 3.0 eSATA 8-Bay Hot-Swap 2.5/3.5-Inch SATA III Hard Drive Enclosure with UASP (S358BU33ERM) that I originally tried, this enclosure seems pretty stable. The StarTech reported the same serial number for each drive, whereas this unit at least reports a unique identifier for each disk within the array, even though it isn't the actual serial number. This is important if you ever hope to manage the disks using PowerShell in Windows, for example, where sometimes the only way to differentiate between same-model disks is via the serial number. (If you use WIndows Storage Spaces and manage it via PowerShell, you'll understand.) This unit was also cheaper than the StarTech and provided a nicer front-panel interface.

A major design difference (likely resulting in the significant cost reduction of the unit) is that there are no latching drive carriers that one typically finds on other units of this type. Instead, one uses two black screws to attach a small plastic "handle" to the front of the drive via its mounting holes, then slides the drive into the slot, engaging it into the SATA and power socket combo in the back of the unit. Then, one must flip a holding panel over four drives at a time (there are two panels, top and bottom, each covering four drives). The panel is screwed into the frame of the unit and holds the drives in place. . There is some foam rubber on the front of each drive handle that presses against the panels and secures the drives into their sockets. I've attached a photo to show how this retention system looks. To remove a drive, the little "handle" can be pushed down to act as a cam that pulls the drive from the socket so that one can grab it and remove it. Without the handle, you need thin fingers to grab and pull it. :)

The advantages of the bay and drive insertion design are lower cost, and you can insert drives even without the handle when you want to quickly access a drive. The disadvantages are that the unit is difficult to use on its side because gravity is not helping to guide the connector at the back of the drive into the socket in the back of the unit - so you have to "angle" the drive to make sure it gets inserted. Even so, I am using the unit on its side with no problems, since I don't insert and remove drives very often. If you use it standing up as designed, then you probably won't notice this.

I am using this unit with Division-M's DriveBender software, and I also tested it with StableBit Drive Pool. Both pooling software worked beautiful with the enclosure, but for those trying to do the same thing, be aware that if one of your disks is failing, the enclosure may detect it, in which case the entire enclosure will go offline, and the LED light representing that drive will start blinking on the enclosure. This behavior is not documented anywhere that I can find, but I verified it through testing. The enclosure may not go offline immediately, because it may take time for it to be given an operation on the disk that exposes the failure in such a way that the enclosure can detect it, but when it does, down it goes and starts flashing the light. This is a bit problematic since the disk may still be functional enough to at least evacuate the data off of it, and the enclosure can't be used for that purpose. I ended up using my smaller 1-drive USB 3.0 dock (it doesn't go offline on errors), putting the failed drive into it, and copying what I could back to the array, eventually putting a new drive into the empty slot and adding it to the pool. Since I did that, the array and the pool have been up and chugging along with no problems.

Whatever application you are using this for, I suggest getting a drive scanner like StableBit Scanner or other similar products to monitor your drives for problems. It could save you a lot of headaches in diagnosing the array when it goes down because it is functioning as designed (bad disk detected).

PROS:
-Button on front panel for switching the interface between eSata and USB 3.0
-Unit can be configured to turn on and off with main computer
-Returns a unique but fake serial number for each drive (the StarTech returns the same fake serial number for each drive)
-Passes SMART information from disk drives via the USB interface (not always the case with these enclosures)
-Indicates problem disks by flashing the drive's LED
-Less costly than other comparable enclosures such as the StarTech I also purchased (and later returned)
-Smaller and lighter than the StarTech

CONS:
-No drive carriers.
-Side orientation not easy to insert drives into because of carrier-less design.
-The entire enclosure goes offline when a bad disk is detected (its LED flashes, noted as a PRO above)

5.0 de un máximo de 5 estrellas All three of my Probox 8 Bay Enclosure work great !!! 17 de diciembre de 2013
Por Dale Dressler - Publicado en Amazon.com

I have three of these Probox 8 Bay Enclosures. I bought one in 2011, one in 2012, and one February this year. They are connected to three separate computers. Two of them are on USB 3.0, and third on eSATA, and they all are directly connected to the motherboards. The two USB cases are used one for games, and the other for movies, the eSATA is used strictly for my miscellaneous storage machine. All three computers use a Gigabyte GA-990FXA-UD5 motherboards with an AMD FX-8350 CPU and 16gb memory. Each Probox 8 Bay Enclosure has 8 x 2TB Western Digital drives of various models. I have mixed WD 2TB hard drive models, (red, blue, green and black labels). The 5400 rpm drives works right along the 7200 rpm in the same enclosure. I guess I am like "the guy who buys a new car every time the ash tray is full". Some day I will be bold and daring and start learning how delete and format drives...lol.
I can access all three Proboxes through the network via the computers and a network router. I was impressed that the BIOS recognizes them on boot up. I like to mess around with different OS's. I am able to boot up various Windows OS (NT, 2000, 2003, XP, 7, and 8) and LYNUX from hard drives within the enclosures. I can access all the drives though the motherboard boot up menu which is separate from the BIOS menu The sleep modes of the enclosures work great (never shut them off), and auto fan controls are always working. I must say that the one I bought in 2011 works just as good as the one I bought in February of this year. I do like the "tray less drive bays easy for swapping drives. My cases are very quite. I recommend the Mediasonic H82-SU3S2 ProBox 8 Bay External Hard Drive Enclosure. I hope this was of some help to you.

5.0 de un máximo de 5 estrellas Perfect for 64TB of storage on a single USB3.0 port 21 de octubre de 2015

I bought this box (Mediasonic H82-SUS32 ProBox 8 bay 3.5") on the recommendation of a friend. I wanted 64TB on one USB connection. I bought 8 x 8TB Seagate drives. Formatted them for GBT. Spent a week copying 64TB to them. Put them all in the box. Works great. Prior to this, I had a dozen drives connected to a couple of multiport USB's..... several times a day one or two would disconnect and cause others to reset... I've had this box going 24/7 for the past 2 weeks. not a single reset.
There is one drawback worth mentioning. With the cabinet door closed, drive temperatures are 4-6 degrees centigrade higher than with the door open. The cooler the drives run, the longer they stay healthy. If any of the Mediasonic engineers are listening, the door should be perforated... The intake at the bottom may look wonderful in an engineering drawing but it sucks in real life. I bought a 15' foot USB cable so I can remote the box far enough away so I can leave the door open without hearing the fans. At a room temp of 24 deg cent, the drives run 32-34 deg cent. With the door closed, they run 36-40 deg cent.
Except for that one issue, these boxes are perfect in every way.

Works as expected.

Pros:
- Stores a lot of drives and TB
- Doesn't care about drive size
- No issues with connecting drives

Cons:
- Multiple simultaneous transfers cause a major transfer slowdown even if there is available bandwidth on the usb 3 port.
3.0 de un máximo de 5 estrellas Great for high volume storage, low performance in RAID applications 16 de marzo de 2017
Por Lee Burch - Publicado en Amazon.com

It does do what it says, assuming your card support port multipliers, you can definitely attach 8 drives and access them individually or use software RAID to group them. The multi-speed fan is nice as heavy use and/or a full cabinet can get warm.

The issue is very much speed, generally anyone running 5-8 drives is likely going to be running some kind of RAID, likely a RAID6. Here the probox does not do so well. Individually the drives may have typical performance, 150-200MB/sec but when addressed by a single esata cable as a group performance is not good. All the drives crowd the bandwidth and you will see significantly diminished performance. I have 6x3TB drives in RAID6 which all individually (even in the probox) can do 150MB/sec+, but reading from the array when under no other IO demands is between 15-80mb/sec. Even with relatively small 3TB drives taken in aggregate it takes a LONG time to either check, copy or migrate the array.

Next time around I will be using SAS, as there are affordable 8 bay SAS drives which provide a full 6gbps to each drive, as opposed to a single ESATA connect which provides ideally 6gbps but in reality far far less in real world applications.
