Review on SK hynix Gold S31 500GB SATA Gen3 2.5 inch Internal SSD - High-speed Solid State Drive (SSD) 500GB - up to 560MB/S - Compact 2.5' SSD Form Factor - SK hynix SSD - Reliable Internal Solid State Drive (SATA SSD) by Charles Parente

First you have to accept the SK Hynix terms without being able to read them (they're sealed in the box, and by opening the box you agree to the terms and conditions - although there's a brief description on the packaging). Second, the performance is terrible. Several tests show that he writes FASTER than he reads. This is exactly the opposite of what it should be. The third photo shows the performance of the CHN SSD. Another test shows an average read speed of CHN SSD at 7900.68MB/s while this drive is 1939.57MB/s. Of course I expected a better performance!
