Performance is fantastic, a great upgrade for 2012 MacBook Air models.

The performance seems good too, although I no longer have the zeal to download programs and benchmark few kb/s differences in read write speed, the system does feel faster

Great performance!

The only thing I'd have liked to see would be even better performance, but that's minor

Picture is of Black Magic Disk Speed Test, reading and writing a 5GB file, awesome performance!

Great performance and easy installation.

Easy mounting and flawless performance.

Best performance 500Mb/s read, 400mb/s write

This will irritate you eventually as it'll stick up in the smooth underbody surface
