Is it possible to created a Raid 0 in Mac Pro and then boot off of it. I can do it with my HP, I cant seem to see how to do in on a Mac Pro. (I have the 2008 Mac Pro).
As far as what the drives can do, no, it's not wrong. So long as you're aware of the issues involved, namely time consumed when something goes wrong (eventually will, not if).Hi all, i'm about to set up my system aswell only i will be using 4 sas drives in raid-0, thats the fastest i can get my boot drive, or am i wrong?
Also with this setup ,will it be a problem that when working with FCP the scratch disk will bassicly be on the same stripped raid set, or will this be no problem because of the high I/O of that stripped array ?
I have an external eSata drive that can also be used as a scratch disk that should be able to go around 150MB/s, but i wonder if this will be necasery since i expect a far higher number from my raid-0.
But i do this mostly to get my set up as fast as i can, also when not doing any editing on my system, i hope it will fly ;-).
I use a 8core mac pro thats 1,5 years old now with the raid card installed.
And before you ask, yes of course i'm backing the whole thing up to on a hourly basis ;-).
I understand with the RAID card. It's custom made for Apple, and unfortunately, it's crap. Slow, expensive, only supports one OS, and has battery problems. In simple terms, it's junk.Hi, ty for the reply , It is the macpro raid card from Apple and i also have 8 gig ram installed, and with the 4 sas drives installed thats all THE Card can handle thats why i wanted the external raid drive with esata for fast external storage to.
what an odd way to do it, why havent they made it easier then that? so basically, you cannot install a brand new OS to a RAID array?You create your RAID0 array and use the SL install disk to clone your existing boot partition onto the RAID0 array.
Then you boot with the option key pressed and you should be offered with the option to boot into the new boot partition.
If not you can use disk utility to repair the partition or the permissions.
hit us up with some benchmarksHope it's not to slow ;-).
im not familiar with RAID testing programs.. anything that can test the various bit sizes, e.g. small writes/reads to large writes/reads.What kind of bechmark program do you want me to use ? ;-).
that would most likely be the easiest way. if thats possible then you answered my last question, thanksAs for the set up, i was thinking, i'm gonna erase all the disk and build the raid-0 with the Raid configuration program on the SL disk,and then install the os also from the SL install disk, and then put back my old sytem from my time machine backup. This seems like the easiest way to do it , or is there a problem if i try to work like that ?
You could try AJA System Test.What kind of bechmark program do you want me to use ? ;-).

ugh so true! but so worth it! i hate taking out loans, mainly because my income is, well, non-existent. cant wait till i have one of these puppies but. let us know how it goes!@dofot9 , i'm still paying for mine too, by the time it's paid in full it will be obsolete again,lol.
Here's mine:I don't realy have anything to compare it with so maybe, if you post some to compare this with it might be more usefull ;-).
