I downloaded the Disk Speed Test app by BlackMagicDesign and my speeds will usually average:

Write 320 MB/s & Read 700 MB/s

I've seen reviews talking about both being 700 MB/s, so why then is my write speeds capping out at 320 MB/s? :confused:

Here's an article by a guy who found a massive difference in write speeds between two mackbook air's he got as well (one being a Samsung SSD and the other being a Marvell SSD)

Did I get a dud? Should I be concerned about this? Is that write speed normal for others?
