I originally thought it was terrible due to disc read errors and gave it a 2 star rating. I've since changed this as the SATA controller card was actually the culprit. These cables do their job well, just make sure you route them properly and for heaven's sake don't tangle or twist them around each other as that will only contribute to more read errors. ;) Pros: Beautiful color, great flexibility in cable management, and long range! I needed 2 feet for the cables and the rest only 1.5 feet, so at 3.3 feet that was perfect. As long as you have excellent cable management in your case and keep them away from interference, they should work just fine. Hopes: I'm a little frustrated that they all go from 1-4 where showing 0-3 would be more likely. and it would be nice to have an option for labels (or include labels that go 5-8 or 4-7, but that would just be a nice addition. Bad: *Edited* I removed this section as soon as I spotted it The problem was with the controller and not necessarily with the cables.
