Like many others, I am waiting on a new mac pro to ship. Not wanting to spend more than I have to, I got the stock 320G drive and plan to buy other drives externally, likely the Samsung F1 750G in regular or raid version. My original plan was to buy two of those and run them in RAID 0, then use the existing 320G drive as a boot camp drive. As I have such a long wait time, I keep going over it in my head and now I am thinking of getting 4 drives and running software RAID 0+1 or 1+0 and installing the stock 320G drive on one of the eSATA ports, possibly in the spare optical slot or externally. What I am wondering, and am not sure this has been answered elsewhere entirely, is will I be able to use boot camp to boot from the eSATA 320G drive as I will be using the on board eSATA ports rather than an external card? Also, are there any advantages in using RAID 1+0 over RAID 0+1 besides less redundancy? And is one faster than the other? Also, with this setup would I take too much of a hit using software RAID and should I perhaps consider the RAID card? (I am not made of money but I could probably add this later) Finally, if I can't use boot camp from the board eSATA (and I am assuming can't use it with this RAID configuration) is there a way to use it at all or will I need to go with my original RAID 0 plan and backup externally to time machine? I am aware that a lot of this is preference, but I am looking for some technical reasons that tend to back up preference.
