Very informative. Thanks!

In January I swapped 6 of my 10" SATA II cables for SATA III. Seems like I didn't need to. :) 
Good thing I only paid $1.67 per cable.

Yup! No need to get the most expensive cables. However, the article correctly points out that sometimes there may be an issue with quality control.

BTW - If anyone is looking for short SATA cables here is a source four 4 inch and 8 inch cables:

Comes in handy in situations where a drive is close to the motherboard SATA ports.

Thanks Johnny-
I've been telling people for some time now that there is no difference in SATA cables, but of course no one wants to believe that. Wizard's First Rule or something like that.

Anyway its nice to have some evidence to point to, albeit not very scientific evidence. Thanks for this.

I am someone who could actually use more than 20 4 inch cables!

Newegg has SATA's in the 6" range as well.

Nice list - also includes 8 inch and 10 inch cables.

hardly scientific in nature when only a few test subjects are used. Try testing a box or two of those cheaper cables and compare them to better quality versions to see which one has more lemons or causes the greatest number of sata speed downclocks/disconnects.

I've done some of that same testing by being forced to figure out where issues are. Cables can make a larger difference the faster the drives get and I for one would never put a cheap $1.25 cable on my thousands worth of SSD's. May as well wire up your 1500 watt surround sound setup with radioshack's cheap stuff.

Premium cabling is just cheap insurance in the long run.

Also found it odd that they tested that drive with incompressible data(AS SSD/CDM3?) as that won't task the sata channel nearly as hard on the write side of the equation.

groberts101 - The test laboratory at CNET did. Price made no difference. It's the quality, not the price that counts.

I'll see if I can find the test report and post a link.

not a big deal Johnny. I see too many flaws to take much salt away anyhow. Thanks though.

Hi,

I found the article very enlightening. I've a follow up question. Does the article apply to HD Mobile Racks as well, I assume? Meaning if I have an old HD SATA I caddy, that's been working well for many years, I should be able to drop in a new SATA III HD and experience the expected performance gain?

Thanks,
Erasmo.

SATA cables labelled and advertised as SATA, SATA 2, and SATA 3 are identical according to the International standard.

Does the computer have SATA 3 6Gb/s capability? If it does, then you will experience SATA 3 6Gb/s performance. If not, then you will not experience SATA 3 6Gb/s performance. Instead you will experience ssd performance at the same level as the computer's SATA capability.

Of course! I replaced the motherboard but not the chassis. I should have been clear about that :) 
Thank You.
