Installation of a SATA hard drive with the URA-350SA took only a few minutes. PCCloneEX took a few more minutes, and I would estimate the total time of installation for the hard drive and software to be around 10-20 minutes (hooking up the cables to your computer, installing the PCI eSATA adapter bracket, etc.). I like the added protection of the hexagon screws for the outer casing of the URA-350SA. Some might ask why as it could potentially cause an inconvenience if the tool supplied by VIZO is lost. Well, don't lose the tool. Keep it someplace safe along with your other computer parts. Why? Because hexagon screws are not so common, you can be somewhat at ease the outer case will not be removed and your hard drive tampered with by inexperienced hands.

I unfortunately found a con, which was PCCloneEX's inability to be used with the SATA connection. While a USB2.0 is fairly quick for small files, when you're backing up hard drives where the typical capacity is 250GB or more, USB2.0 becomes futile and a SATA connection becomes mandatory. Hopefully we'll see FNet Corporation (the makers of PCCloneEX) update their software so it's more reflective of the current external needs by the consumer. Having BOTH options of backing up your data via USB and SATA, is the way to go.

The WD2500KS was rather quiet in the URA-350SA. I remember reading a few comments on the net about the enclosure being "loud" but this will depend on the type and quality of the hard drive you purchased. My Western Digital 250GB performed just fine and was quiet, according to my observations.

Overall, I was impressed with VIZO's Uranus 3.5" eSATA enclosure. It performed very well with the WD2500KS and I observed no mechanical issues. The enclosure might be considered a little more expensive than most enclosures, but the quality of the enclosure all the way down to the AC adapter, are above the quality you would expect to see in a typical external enclosure.

The URA-350SA is highly recommended and then some.
