Currently I have 2 250GB drives in a RAID 0. The performance increase is substantial and I was thinking about adding another 2 drives to it to further increase performance and storage, being as I have the extra drives laying around anyways.
But I remember reading on here awhile ago (> 6months) about how MB RAID solutions inherently have a lower speed limit than PCI-E RAID because of the respective buses they operate on. The poster claimed that for this reason, there is no point in putting more than 2 drives on a RAID 0 MB bus because it would reach the speed limit and not improve performance, only storage. In order to maximize the speed available with 3 or more drives in RAID 0, you need to use a PCI-E RAID controller card. The guy had some math to prove it and really seemed to know what he was talking about. But I haven't been able to find that post again. Can anyone back this up? Does anyone have any experience with this?
Thanks
Eric
