Currently I am running 2 80gig sata HD's in Raid 0, and recently ive been looking into more storage. I would like to buy some larger sata hd's, but i have noticed that some of the larger hd's run on SATA 2 and these are the ones that have a 16meg buffer. I am wondering if there is a requirement to run sata 2 or if i can use it just like I use normal sata. Thanks
