Unless you have a PMP on the other end of that SATA link with a bunch of striped drives, or an expensive SSD, you won't notice a performance difference between 3 Gb/s and 6 Gb/s link speed anyway: no single mech drive on the planet can come close to pushing 300 MB/s let alone 600. The fastest 15k SAS drives are peaking at around 200 MB/s IIRC. And there are few [affordable] SSDs that will saturate a SATA II link, let alone a SATA III link. My advice, FWIW, is to simply ignore this, unless you plan on attaching a device in the near future that can actually exceed 300 MB/s. Currently the only way to do this is with striped mech drives on a PMP, or with a $500+ SSD. -- Stan -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
