    So as in my previous thread (thanks to everyone for the help), I'm going to do RAID 0 with 2x 4tb drives and use goodsync or an alternative to backup those up. The reason being is that I'd prefer to have a physical backup units not connected to my pc in case anything happens.

    I have a gigabyte ud5 x79 mobo and was wondering if there were an detrimental reason why I should not use the Marvell 88SE9172 controller for raid 0? Since I only have 2x intel sata3, I'll be using those for my two ssds.

    Is there a difference between sata3 and sata2 for raid0 with HDDs?

    Thanks!

    You won't be able to hit the speed barrier of sata 3.0 with two mechanical HDDs in raid0 so it won't matter much which you choose.

    it really doesn't matter as far as I know but best thing to do is set up a temp software raid and give it a twirl. Run some synthetic tests and real world tests. I just tried some with 6 3TB drives using the windows software raid and it was super fast. The drives were between intel controller and the other one which i think is marvell. I had 700+ MBps with 6 drive in crystal mark or whatever. I also had 500-1100MBps transferring to RAM :)

    Also since concurrent reads exist you could just do RAID 1. You would still get the 2x reads but only 1x writes. Double check though to make sure it works. I'll be doing a RAID 10 of 6 or so drives so I'll have 6x read and 3x write vs 6x read and 6x write for a RAID 0.

    I have more of a need to read than write so having that extra redundancy is worth the write penalty since I still get the full read speed. Granted I do loose 50% capacity but I got enough drive where I am not concerned.

    Why the RAID0 of HDDs ?
