Bought this enclosure to use as RAID-0. I get sequential reads of up to 220mbps (avg. 185) and write of up to 155mbps over eSATA.

- Hardware integrated RAID, unlike many other products which requires you to have a PCI-E RAID card.
- Support most RAID configurations (including JBOD).
- Fast!
- Nice design. The visual indicators LED are great. Solid feel.
- Quiet fans. Multiple speeds.

- USB3 works but you might get problems or slow speeds depending on your hardware (if you have Etron controllers on your mobo = problems most likely). But that's a problem with USB3 in general, not specific to this enclosure. Until USB3 gets better drivers and support, it's not worth using if you're looking for performance. Use eSATA for now.
- If you're new to RAID, you might find it difficult to setup. There's no GUI or "wizard setup" a la Drobo. Otherwise, it's quite straightforward. Make sure to read the Quick Setup manual, very useful for disk and layer configurations.

I Choose the Right Brand This Time (Thankfully) Dec 11 2012
By Mike from Jersey - Published on
Verified Purchase
I have had this Raid Enclosure for some time now in order to give a fair assessment for it. This is what I experienced.

First the Good: I haven't had a minutes trouble with it since setup! I have this enclosure sitting on a CyberPower 1500PFCLCD battery backup with plenty of overhead in case of brown-out. I have it configured with Raid10 with all slots populated with 3TB Hitachi disks. This yields two volumes of 5.45TB of usable storage space. It is a small inconspicuous piano black case that would work in home/office or a data center operation. Like I say, not a minutes headache since it's been running 24/7 for almost three months now.

The one really useful feature on this enclosure is that it has a loss of power detector via the USB connection that safely shuts the unit off. By simply pulling the USB cable out, it will shutdown and restart similar to the host with No Issues.

The Not so Good: During the setup the enclosure driver kept dropping out on me for no good reason. This unit came with a new line cord of only two feet in length. So based on the cheesy line cord supplied, I had some inclination that perhaps the supplied USB 3.0 cable was also a cheaply made cable I stopped the setup and dug out a known good hi-speed cable and switched them out. The dropout problem ceased.

Also to note, that when you begin installation you must decide which Raid type you desire of course. You also need to set that Raid configuration along with the number of disks present! In other words you have to define ALL disks. Disks cannot be added to a volume later on/or changing disks Size either. My suggestion if you have limited disks on-hand at setup, is to only populate the Top Four Slots to make a volume then later on add the remaining Four disks to make up the second volume. This will avoid having to Format your disks to achieve a greater size volume or creating a New volume.

Summary: This device came shipped in a very solid packaging similar to an OEM computer case. It was well thought out in that respect. If you have problems in the beginning. Stop what your doing and get a fresh USB cable and begin again.

I would HIGHLY recommend this product.

EDIT: Ordered a second unit Jan 2014, sent email to inquire about using 4TB drives. I was advised by maker that the enclosure would support 4TB drives without firmware updates.

Excelent Product, Bad Documentation... Some TIPS! May 19 2013
By Javier - Published on
Verified Purchase
Let me start by saying that I was actually going to return the two ProRaids I bought, and would have left a 1 star rating, if not for some information on the Mediasonic forum.

I bought two of this things to setup in 2xJBOD mode each one, width 4x3TB and 4x2TB hard drives on each one, which gives me 12TB and 8TB on each ProRaid.

The first problem was actually caused by one of the four WD Reds I bought. Even though SMART was telling me all four Reds where ok, one of the 3TB Red hard drives was broken, and had to be replaced. So, check the hard drives.

So, after changing the faulty Red, all was fine. I added 4x3TB hard drives on the top "layer" of each ProRaid (a ProRaid can be used in full or in half, and each half they call it a layer), and all was fine.

But when I tried to add the 4x2TB hard drives to the second layer of each ProRaid, one of the ProRaids would get into error mode and kinda freeze, and the other one would only let me use 2 of the 4 hard drives.

To make this review short, this is how you should really add the second layer if you haven't added all the hard drives at the same time the first time and you are having problems.

1) Turn OFF the ProRaid
2) Remove the hard drives from the original layer (that where rightly initialized, in my case it was the top layer)
3) Fill the non working layer with hard drives
4) Turn the ProRaid ON.
5) Press the "Change Modes" for 3 seconds to start the raid initialization.
6) Hold down the confirm button on the back until ProRaid turns OFF.
7) Turn the ProRaid ON. At this point, all 4 hard drives should be recognized perfectly.
8) Turn ProRaid OFF
9) Insert the original hard drives on the original (empty) layer.
10) Turn the ProRaid ON, and you should have all 8 hard drives recognized in 2 independent JBOD ARRAYS without loosing a single bit of the original array!

I used this same method for the second ProRaid I have, which, instead of only allowing me to use 2 of 4 hard drives on the 2nd layer, would actually give a hard drive error and go into "error mode".

The only difference is that steps 4, 5 and 6 have to be done more or less quickly, or the ProRaid would get innto "error/freeze mode".

Does not support RAID 5 over 8 drives Aug. 4 2014
By Remigius J. Onyshczak - Published on
Verified Purchase
This unit does not support RAID 5 over all 8 drive bays, but rather it supports RAID 50 - RAID 5 over 2 groups of 4 disks and RAID 0 over the 2 groups of 4 disks. This results in capacity of 6 hard disks, not 7.

Best USB3/eSATA RAID Enclosure for the Money July 25 2013
By Dung V. - Published on
Verified Purchase
The subject say it all, great enclosure if you're looking for some kinda centralize your files into 1 or 2 big volume.


I do consider to buy second one soon.


I don't like the way how it device the backplane into 2 layer, 4 drives per layer. What that mean, if you're installed 8 drives and configure it as RAID-5, it will automatically create 2x RAID-5 volumes, 1 parity drive per layer/volume, you lose 2 drives there. If you're configure it as RAID-50, it's basically combined the 2 RAID-5 set into 1 volume, you still lose 2 drives here. Other than that, everything else work as expected.

1 thing I want to mention, before you purchase this enclosure, you need to make sure your drive (s) support "SMART" capability, otherwise you will experiencing many problem with drive failing off the array.

I Highly recommended this enclosure to everyone who don't want to spend a lot of money for high-end RAID system, this enclosure is best for the money.

Potentially fatally flawed unless Mediasonic can come up with some good firmware Feb. 22 2014
By James Zachary - Published on
The cabinet is nicely made and the controls are fairly intuitive and easy to understand.

Installing hard drives is soooo easy. The fan noise is minimal and even adjustable.

Unfortunately the USB 3 connection is finicky. I had to make BIOS adjustments on my notebook computer to get the enclosure to connect at USB 3 speeds.

It doesn't seem like Mediasonic can or will upgrade the firmware. So unfortunately you might have 8 huge hard drives connecting at USB 2 speeds. That can be a bummer.
