Hello, I've been trying to figure out a solution as to why my SSD is slow. I have a late 2011 15" macbook pro with a OWC Elektra 6g 120gb ssd. I ran Blackmajic speed test to measure the speeds and came up with the image below. I see many posts showing 480+ speeds. The disk has about 26gb of free space. It is installed in the correct slot where the original hd was. Any help would be great.
