Thread: Seagate ST3640323AS hard drive

Good day. I bought a Seagate ST3640323AS 640GB 7200RPM SATAII 32MB cache, discovered on the mounting plate with a jumper
1. «Limit to 1.5 Gb / s operation»
2. «3 Gb / s operation»
At this point, is at the 1 position.
Explain that in the 2 treatment and whether they use?

This is only the choice of operating mode - SATA 1.0 or SATA 2.0.

Depends on the controller which regime to stand. If the mother keeps SATA 2, it is necessary to put «3 Gb / s operation» - will be faster.
