My friend and I have installed a RAID controller card, an Adaptec 6405E. It comes with four SATA III cables . . . and what appears to be a cable and plug for a motherboard 2xUSB2 header.

Is it a USB cable? What is it for?

Thanks

Hello,

My name is Luis and I'm with Adaptec Tech Support
The extra lead on the cable is called the sideband connector. It is used to connect the controller to a backplane that uses SGPIO standard to communicate with the controller. If you have directly cabled drives and no backplane, just coil the cable and leave it to the side.

Thanks,

luis

Thank you very much!

It would have been nice too have some documentation on it, however.

Also, I have a thread titled "RAID 10 experience" where we found ten lapses in the 6405e's documentation. It's a nice controller, and deserves better documentation.

But I will tell my friend about the sideband connector. Just the info we needed to put our minds at rest.

Good afternoon

I've been using Adaptec 6405 for 2 years with SSD raid 0 array and for specific gaming desktop (Flight Simulator wich uses a lot CPU and his add-ons wich uses extensive sequencial and random files).
So, I know the benchmarks doesn't translate the real power of raid cards (maybe isnt true for Areca cards) but can you tell what king of performance can I expect from Adaptec series 8 on 4K random Queue Depth 1 (most Windows usage)?
Thank you
Thank you.
