Pros: I've been buying these in various lengths from 6" to 18" for a few years now, and they perform well with minimal impact on case airflow and quality sleeving that's moded in so it won't fray or loosen over time.
If you poke around here at the 'Egg, StarTech makes them with various angled and straight SATA connector combinations - you'll never need to "tweak" a cable into place.
Cons: None, really. They lock into the SATA sockets well and just do their thing from then on. :)
Overall Review: Recommended for: HTPC, SFF and mITX builds, "stealth" cable layouts, cramped spaces in general. (They'll work in a standard ATX case as well, of course. :D)
Pros: ROUND cable makes it easier to route. Right angle end is oriented the correct way (points "down" for the drive, not "up" like some others) Length is awesome for short runs. Latches work as expected.
Cons: None at this time.
Overall Review: It's a SATA cable. Not much to write about. It does what it does, and does it very well.
Pros: Fits and works - looks good
Overall Review: Would buy again
Pros: A cable is a cable, nothing extraordinary.
Pros: I do a lot of custom wiring, my only problems are with the flat sata cables. These made running wires under a motherboard a lot easier to do. There are a lot more flexible when wiring up a column of hard drives.
Cons: Shipping costs are too high.
