On my motherboard I have "SATA 6Gb/s" ports, but when I transfer I typically get 70+ MB/s. It's a "SATA 6Gb/s" disk.
I think I have the same issues with my old PC I use as a server, but it has "SATA 3Gb/s" speed.
What does "SATA 6Gb/s" and "SATA 3Gb/s" mean? Is it total bandwidth, so with 6 SATA ports – working at the same time – I would get 500 MB/s? It's still far off my typical 70+MB/s.
I know the quality of my hard-drive is an issue, it's a plain 3.5 non-SSD, and I know file size and file number make a difference, but is it supposed to get close to 500 MB/s?
