First and foremost...greeting and salutations!

I'm rebuilding my machine very soon...I upgraded from W7 to 10 and although everything worked, I did "lose" my raid5 setup briefly. I found compatible drivers to get me back but transfer speeds have been just awful. In any case, I think one of my drives is failing and so I'm taking the opportunity to start over. I'm backing up right now (at 20mb/s....uuuuuuggggggh) so while I'm waiting on that, I thought I'd research how best to do the reinstall...which is how I found this place!

So here are the details. My motherboard is an MSI 790FX-GD70...it's got 6x SATA ports that are controlled by the SB750 chip...My plan is to connect 2x drives (plugged into slots 1 and 2) to run in a Raid0 for the main OS and then use the other 4x slots for a Raid5 setup. The MB also has two JMicron SATA plugs and I'll be using one of them to plug my bluray drive into.

Ok, so my very first course of action is to update the bios (which I've never done) and then create the raids in its setup and then install W10...here is where I am lost. The old manual tells me that I need to provide the proper drivers upon installation for Windows to recognize the raids correctly...I suspect I never set it up correctly in the first place and I'd like to get it right. So which drivers do I need for the initial setup?

Thank you!

Thank you very much for your help! I didn't know about having everything disconnected while installing so thank you for that as well!

Two more questions if I may: (1) The drivers you pointed to...I assume they should also be used when finally installing the Raid5 array as well? (2) Is it possible to disconnect everything and do a complete reinstall and somehow keep the Raid5 data untouched or am I destined for a formatting no matter what?

Again, thank you for your time!

Incredible! Thank you thank you thank you!
