The intent of the cable is to allow you to connect an SAS Device to a SATA controller.

It is supposed to use two SATA ports to maintain the SAS Speed wile pulling power from the usual 4-Pin Molex connector.

The device failed because it was defective.
Cables by: Michael A. McKenney on 8/15/2009
I use a LSI Logic 8708EM2 SAS RAID controller and Supermicro SAS enclosure. I only use the cables recommended by LSI Logic and Supermicro. I talked to LSI Logic about the correct cable that they tested with.

The cables are $50 each.

You can use either SAS or SATA on this controller but not both. The Supermicro enclosures hold 8 x 2.5" SAS drives like a HP Proliant server.
We will do everything by: Theo Valich on 8/14/2009
When it comes to testing equipment for our readers, we will go beyond the call of duty with equipment, and we will not remain silent on that.

We also had an issue where Cooler Master's UCP 900W power supply suffered a melt-down after the fan stopped spinning out of thin air - and fried a multi-K USD setup.

When it comes to this particular case, it is a clear cut as far as I am personally considered. We did all the tests on a motherboard with a SAS controller. Then, I noticed a "SAS-to-Dual SATA" adapter and I bought TWO of them (as written in the story), and connected the TWO adapters to TWO Seagate Cheetah's and connected four SATA cables onto the motherboard.

One cable works, one hard drive works. The ONE cable in question fried ONE drive and the motherboard. Core i965 works, Corsair DDR3 memory works, nVidia Quadro FX 4800 works, SECOND Roline cable works, SECOND Cheetah drive works.

If your assumption was correct, then I would have two fried cables and two fried Cheetahs. One drive works flawlessly (knock on wood), same thing with one Roline cable.

But one cable went bust and took motherboard and a hard drive with it.

No hard feelings, just honest reporting.

I feel your pain, but it is good to hear that somebody on the whole Internet saw something in the store, bought it and saw that it doesn't work.
Too many sites write that everything is sugar and spice, and real world tales a different tale.

"Sorry, it's not Roline's fault but all yours."

So Roline produces a cable that it says can do this (The cable is an "SAS to Dual SATA" adapter), the review uses this and you blame them for uses the cable for it's intended purpose?

I simply cannot believe that you've done that. You write hardware reviewer for two decades and did not know that you MUST NOT connect SAS components to SATA controllers?

Take a look at the SAS specs... They differ already at the electrical level.

You can do the opposite however (connect SATA drives to SAS controllers), since a SAS controller can detect wheter an attached device is a SATA drive and then adjust its electrical interface to SATA transmission modes.


Sorry, it's not Roline's fault but all yours.

Whew that's rough. I wonder how many components were fried world wide from this shoddy product.
