Easy to install hard drives and works great.

I am now using the power sync mode where it powers off when I shut my computer off, so I have to turn the probox on every time I turn on my computer.

It simply doesn't work properly with USB 3.0 or eSATA.

Very easy to use. Just plug the hard drives in and turn in on. BE SURE to set the switch to the proper connection (USB or eSata) or else the drive enclosure shuts down. This is due to the PowerSync feature. For example, if you are connecting via eSata and the switch is set to USB (default), then the device will detect no power going through USB and shutdown. Apparantely, the other person who gave this item a negative review didn't realise this.

I'm using the Mediasonic HF2-SU3S2 on a PC running Vista, which is connected to a Rosewill RC-219 PCI Express eSata SATA II Controller Card ([...]

Only cons I have, though nothing major is:
1. Power connection is on the side, not the back
2. Takes a few seconds for each drive to power up and be recognized.

I'm planning to buy another enclosure for another PC.

Note: According to the documentation, USB 3.0 connections is backware compatible with USB 1.1 & USB 2.0.

Received this as a gift off my wishlist. This drive enclosure is an attractive addition to my desk, and when it is properly recognized by Windows 7 and Ubuntu 12.04 'Precise' (see cons), it performs quite well, offering blazing speeds up to 135MB/sec per Roadkil's Disk Speed test.

Pros:
* Easy hardware setup -- attach the brackets to the front of the drives, plug them into their slots, close the case
* Attractive, sleek case with blue indicator lights (one each per drive, fan speed, interface, etc.)
* Power cable has 90° bend for security (it's on the side, which may seem like a con, but really, it keeps it from being tugged out unexpectedly)
* Offers (but see cons)... offers two interface types (eSATA 6GB and USB 3.0)
* Supports read speeds as fast as my hard drives attain when inside the computer (134.99 MB/sec)
* Ships with all necessary cables and power adapters
* No setup disk required; just plug in and go (this works best for my system with the orange sync mode enabled)
* Very easy to remove from the system in case of an emergency -- let insurance replace the rest, and keep your data drives safe
* Hardware assembly instructions are quite useful and accurate, and will quickly and easily get you to a ready state (but see cons)
* The device offers a sync mode that has a nice 15-second delay then powers off, when the computer is turned off or put into S3 sleep. This avoids unnecessary drive power-cycling cold reboots or mistaken sleep cycles
* The power supply provides adequate power for four drives, even with all in an active state (e.g.

This product is a great addition to anyone interested in consolidating their hard drives. The backwards compatible usb 2.0 port works fine on all of my PCs and on Macs that I've tested it on. It's very easy to set-up (< 5 min) But be sure to read the setup card provided (note: USB 3.0 cable provided with case).

Pros: Put 4 x 2TB harddrives in case and they were instantly accessible on Windows Vista, Windows XP, Windows 7 Ultimate, Ubuntu 10.10, and Snow Leopard.
Cons: None so far. (This is the second one I am buying)

Easily handles my 4 x 2TB drives on eSATA and USB3.0. I tested both interfaces and getting over 100MB/sec sustained reads on both interfaces! I am using this for a Windows Home Server (WHS) and it is perfect since it does not do RAID, so that I can let WHS handle folder duplication instead. I intend to buy another one of these to expand my WHS capacity in the near future.

This is one of the few enclosures I could find that does not come with some kind of crappy (as in low-end) built-in RAID controller. When using in WHS, it is preferable to *not* use RAID and to let WHS do its folder duplication, so this is perfect and cheap for that purpose. Make sure your eSATA ports can handle a port multiplier or you will only see one drive or none.

Cons:

None so far. Documentation was a little weak, but not hard to figure out.

I did think it was broken at one point because its default setting is to power down if it does not detect a connection to your PC. When I switched from USB3 to eSATA, I had to tell it to change interfaces (button on front) or it thinks its not connected and powers down. You can also turn off this auto-sync power setting as well. Once I got that figured out, its been perfect!

I've been jumping through a few hoops with other potential NAS solutions; and I've been hearing negative feedback on network-attached implementations, such as reported Gb Ethernet device speed being far less than we might expect from potential performance benchmarks. Other NAS implementations I purchased recently had very preclusive feature sets such as auto-formatting of drives (you can't plug in a formatted archival backup drive as is), non-support of native DOS features (which thus lose your special icons, vital descriptive and archival properties, visual formatting, etc.), and questionable restoration paths, should the NAS device itself go down.

In shopping around with all these considerations in mind, I am now looking for the versatility of potentially plugging the device into perhaps the USB connector of an Ethernet hub. Wireless might suffice for some implementations; but I want, if performance isn't really satisfactory when operating as an NAS device, to be able to connect directly to the machine. Thus this enclosure fits all these requisites, even at a phenomenally better price as compared to Promise or Data Robotic alternatives.

Just to be sure, I confirmed the following with Mediasonic online support forums:

1. Yes, because the unit *is not* a RAID enclosure, *you can* operate the unit with just one drive (or however many drives). This is a substantial advantage for my use, which largely depends on manual backup and mirroring (in just a few clicks), and otherwise may or may not depend on other, proprietary backup or mirroring technologies, which depend on no more than JBOD.
