Legion Hardware - (Samsung SM951 512GB)
 

Not only is the Samsung SM951 faster but it is also cheaper, around 10% cheaper when comparing the 512GB model to the Intel SSD 750 Series 400GB. Granted, at a cost of $0.89 per gigabyte the SM951 isn't cheap, it is considerably better value than the performance SATA SSD's. The Samsung SSD 850 Pro 512GB costs just $270 ($0.52 per gigabyte). So while the SM951 might cost around 70% more than the SSD 850 Pro, it is well over 70% faster.
