Mine isn't a MacBook Air, but I have a 3 SSD RAID 0 in my Mac Pro and it gets stellar results in Aja but lackluster results in Black Magic. It is also due to the compression issue as I am using OCZ Vertex 2's.

Also to note for the 2012 models...there are both Toshiba and Samsung SSDs being used. The Toshiba tends to be used more in the 64/128 GB models while the Samsung is for the 256/512 GB models. This is all per this review:
Another thing to note is....like the OWC drives, which are Sandforce drives, the Toshiba drives in the 2012 models are also Sandforce. So with Compressed data, you will get slower speeds.
Also, if you are using Filevault (which with a laptop you should be), the Samsung drive is going to perform better because of the compressed data.
Interestingly, I got the i7/256/8GB model....it came with the Samsung drive. Using the Black Magic speed test:
Write avg: 403.5 MB/s
Read avg: 446.8 MB/s
After Filevault was interesting....speeds went up:
Write avg: 422.8 MB/s
Read avg: 449.0 MB/s
I was happy with that.
As for Black Magic......it's definitely going to show slower speeds with the Sandforce drives. I have an old OWC 3G drive in my Mac Pro......with AJA I get speeds in the 200's....with Black Magic I get pathetic speeds....on par with traditional drives.
I think the Sandforce drives used to be the best....but I think others have caught up.
