I just bought a MBP 13" mid 2014 with a 128 GB SSD. When doing a disk speed test with the Black Magic Design-app, I only get about 210 MB/s write and about 510-550 MB/s read.
All the benchmark videos I have seen using the same app all get about 310 MB/s write and up to 700 MB/s read.
Is there something wrong with my disk? The computer seems fine in daily use but I want the performance I paid for.
