In terms of operating system compatibility, I reckon they just throw that in to impress those who don't know better. That is to say, if the adapter
isn't compatible with a given operating system then it isn't making the SATA drive appear as a proper PATA drive.
I mean, even DOS works with RAM drives (good luck finding something faster then those).
You might be onto something with the ATA speed, I really don't know enough to say otherwise. But I seem to remember that the console
should work quite happily with an ATA133 drive via an 80 pin cable.
Well, I say 80 pin - I just did a bit of research on the things and it turns out they're more correctly known as 80 "conductor" cables. Those 40 extra wires are all grounds to soak up electrical interference - that is to say, they don't add more bandwidth to your IDE bus, they add
reliability. They should offer improvements to drive performance regardless of what your system is "capable of".
It's also interesting to discover that originally if you wanted to use an IDE drive you needed to get an ISA (and then later a PCI) card to do it. Eventually it was Intel who got the bright idea of sticking the controller directly onto the motherboard, but best I can make out the things still run through a PCI BUS.
I found
this site to be interesting reading, though I'm not sure how much of what it covers can be applied here.
Anyway! Plugged the drive into the oldest computer I could be bothered digging out (about 600mhz on the CPU, Windows 98), FDISK'ed it, formatted it, played games off it... I think my oldest rig runs at about 133mhz, if I get bored enough I might plug into that and see what happens.
Downloaded the app from Samsung to try and force SATA/150 but it didn't work (though it did at least detect the drive through the IDE adapter). Guess I'll try and hunt down an 80 wire cable or hijack a SATA capable computer off a friend, see what difference it makes.
Dunno if you're still about BigPotty, but if you are, I hear a lot of people fixed issues with this particular drive by disabling "command queuing"...
