To test, I ran SiSoft Sandra's file system benchmark 4 times for every cable, and then threw out the high and low score for each cable.

The result was an insignificant difference for all 3 cables.  Each one averaged 31MB/s and each cable had an identical low and high score eliminated.  The Wisetech cables performed exactly the same as the Foxconn ribbon cable.

In addition to performing well, I was rather impressed with the Blue UV cable.

I have seen Blue UV cables in the past, but this one shines brighter than anything I have seen previously.  This shot was taken with a UV CCFL at about a foot away.  For the UV there is a $2 premium over the cost of the black cable, but that is two dollars well spent in my opinion.  Wisetech offers UV colors of orange, black, and the blue pictured.  They also offer their standard cables in blue, black, and transparent/silver.  In addition they offer all of their cables in 48cm (18.9in), 60cm (23.6in), and a whopping 90cm (35.4in) lengths.  If you cannot reach a drive in your case with a 3-foot cable, then you need to invest in a smaller case.

Thanks to WiseTech for sending out these review samples.
