Sorry I wasn't clear, I was in a hurry because I was transfering files and upgrading my studio. My apologies

I didn't get a chance to use Blackmagic test, but perhaps I'm not familiar with xbech so perhaps you can clarify the performance of the Samsung 850 EVO 1tb. This results are from another one from the 4 Samsung 850 EVO since I trashed the rest and luckily I had this one left. I think I read the wrong numbers. But the results I gave you which you qouted was usin Blackmagic, except for the single SSD result.
I use 4 drive per RAID 0. The Areca 1213-4i handles 4 1TB Samsung 850 evo installed internally on my 2010 Mac Pro 2.66gHz 12 core with 48 gigs of RAM
I have the MaxPower RAID mini SAS 6G-2 installed on the same MacPro and I'm using 1 external enclosure with 4 600gig Velociraptors 6g and another enclosure with 4 WD 1Tb drives 6g both RAID 0 I got the same performance with both RAID cards with the Velociraptors set up as RAID 0 which was 459 mb/sec write and 482 mb/sec on read.
What I decided to do is use the SSD 4 tb RAID for Hollywood Orchestra, EWSO platinum, VI cube with some upgrades dimension Brass. The External RAID with the Velociraptor for my Kontakt samples which includes other Orchestral samples, Heavyocity stuff and the other RAID enclosure with the WD Black HD for Spectrasonics stuff and misc libraries.
Sorry for the confusion, it's hard to find performance benchmarks with a specific RAID PCIe card using the SSD or HD I'm using, so I though I would post it to help out. But aparently the Areca 1213-4i could be 6G since I got similar performance with the Velociraptors which are also 6G drives.
The reason I got those PCIe RAID card is because it's supposed to break from the 3g limitations with the Mac Pro. I was barely getting 100 mb/sec with a eSATAIII card and 4 WD Blacks in a RAID 0 configuration in an external enclosure!
