Mediasonic H8R2-SU3S2 ProRaid 8 Bay External Hard Drive Enclosure - USB 3.0 & eSATA (Black) Review

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 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.
