I've got 2 512GB SSD I am trying to put in a RAID on my MBP with an Optibay in it. I'm not sure what RAID configuration I'm supposed to use to get one large 1TB drive... I did a Striped 64k, but I tried copying over my original HDD with only 13gb on it and it's going REALLY slow... so I think I did something wrong. Can't seem to find exact settings for the best speed and performance. Anyone have any tips? ---------- Just did some more reading and I think I know what I did wrong. It should be Concatenated Disk Set is what I want not Striped... If anyone can confirm for me that would be fantastic. Thanks.
