Reverse compatibility of 6Gb/sec ports

[PTNLemay]

I got myself a nice 2TB SATA Caviar Black by Western Digital not long ago (before the flooding hit thankfully), but I can't recall if it said anywhere whether it uses 3Gb/sec or 6Gb/sec speeds. I know the 6 is usually used with SSDs, but this seems like a pretty fancy drive. So I wanted to know what would happen if I put a device meant to run at 3Gb/s into a 6Gb/s port. Will it run? Will it run in any way slightly faster (like maybe peak at 4-5 Gb/sec?) Or will it just crash the mobo? lol

What it does say on the box is 64 MB of Cache, 7200 RPM and that's about it...

The port will not make it faster but it will run just fine, mechanical HDD will not max out the SATA 3GB interface but a SSD will.

So even on the 3Gb/sec, any mechanical drive won't reach the peak? I see... Well thanks for that.

Most hdds are ~100-120MB/s which can't even fully use sata 1 (1.5Gb/s = 192MB/s). There are small differences shown in synthetic benchmarks but it doesn't show in real world apps.
