Review on 1TB Samsung 860 EVO SATA III Internal SSD - 2.5 Inch (MZ-76E1T0B/AM) by Matt Venable

I ordered a hard drive and tested it using the Crystal Disk benchmark. This resulted in only 50% less speed than stated in the specifications. I have a 5 year old Samsung SSD with the same OS that showed speeds over 500MB/s in a sequential test. I ran the same test with another Samsung SSD 850 EVO, which also showed speeds in excess of 500MB/s. I made sure that all parameters are the same for different SSDs. I got a replacement drive from Amazon and it turned out to be defective as well. I tried one from Best Buy released the same month and found the same thing. Samsung's quality testing has gone downhill and they should be ashamed for selling so many defective devices. Before responding to my comment, the Samsung person should also note that I have already contacted Samsung and they said the issue cannot be fixed. and return the drive.
