Integrated SAS 6/i(base): 4 port SAS controller (does support RAID 0/1) But I don't know if that is descent hw raid or crap raid...

This was kind of the reason I was thinking software raid.
Has anyone had any raid experience with this card?
Yep - it's real HW raid, though with a 2950, I would have gone for the PERC instead. The integrated SAS is usually a Fusion-MPT (LSI/Symbios) card. Do a 'lspci' to be sure. I've got a few of these configured and I can check the raid status with the mpt-status command (from the mpt-status rpm). Note that doing a 'fdisk -l' only yields one disk when RAID is setup. So yes - it's real HW raid. Just not much in the way of cache, which is why I prefer using PERCs instead...
