My opinion that Crucial MX300 525GB SSD is decent performer and especially if purchased on sale can be good upgrade for laptop. Even if you upgrade from older / smaller SSD it will be good improvement in performance. Clearly recommended choice. Performance is very comparable to Samsung SSD – but Samsung is a bit faster overall.
