Samsung Evo 860 speeds.

Mar 28, 2005
Hi there, question about my new drive. Samsung's site quotes 550 and 520 as the read write speeds and I'm getting 400 and 247. In addition, Samsung Magician gives a "drive not supported" message. It also says unable to detect interface, AHCI mode - N/A, and Rapid Mode - Not supported.

System boots fine, and is set to AHCI in the bios. Speccy shows the drive is connected to a Sata3 port.

Any insight? Thanks in advance.
Chipset drivers? AHCI/ storage driver vs generic one? Is this a used drive or new?
