Sandisk SSD Plus 120GB - Bad Performance

After answering a dozen questions, taking photos and running Crystal Diskmark etc etc, SanDisk have got back to me and told me to contact the retailer. D’you know what? I can’t be bothered: I’ve wasted to much time on this stupid thing already.

It’s going in the bin, and I’m not touching anything from SanDisk again with a 10 foot pole. Lesson learned.
