SATA throttling using external HD cabinet?

[Jiddick ExRex]

I do not know whether my old interal sata harddisk is sata I or II. I was just wondering if this matters at all if I slam it into an external USB cabinet? Wouldn't the bottleneck be the USB connection and not whether or not the interface is SATA I or II?

Yes. USB 2.0 is far slower than either SATA-150 or SATA-300.

Firewire is faster than USB, but still slower than SATA-150

Essentially, you can quit worrying about the SATA-150 vs 300 speed difference, because the disk platter itself can't keep up with SATA300, so there is little or no difference in any case.

Meaning that I can just go buy the cheapest enclosure. Thx CanadaRam, I knew I could count on you

Yeah.

Drives can barely saturate SATA-150 as it is, making the difference negligible even inside a tower.

It certainly won't matter on a slow external bus.
