All the above. And I tend to avoid being a first generation adopter.

I havent played with the 500, but as a rule of thumb, when are you talking about the same amount of data being pushed to two drives of dif size that are of the same gen and model, the larger ones are noticeably faster as they "stay" fast over a greater amount of data. The point where they stay faster is getting longer and longer as the platter density increases.

For example lets say you use 250Gb of space and lets assume the platters are 250gb in a given gen (just keeping it nice and simple here these arent 250 platters but the idea is the same).
This means the platters on a 500Gb drive will be half full (2x250 platters) but only 1/3rd full on a 750Gb drive(3x250platters). This means when you go to stick the 251st GB of data the 750 will be faster at writing it and when you go to read it, it will also be faster.

Another way of looking at, is if you fill up a 500GB with 500GB of data, past the 360'ish GB point it will be a lot slower (most hdds really TANK in the last 1/3 of their space), whereas on the 750 it will only be 2/3rd full and still clocking along nicely in the speed dept. Hell, in the case of the 750Black the read numbers didnt really dip below 100MBs until basically a bit past the 450Gb point (where it kind of plateaued until nearly the 500GB point where it really started to decline below 100mb/s)!

As I always say...get the LARGEST storage device you can afford. If its a 500 instead of a 250 or 750 instead of 500, get the larger one.

Hope that helps.

Wonder how 2 of these drives in RAID 0 would do vs SSD offerings...

I have the Scorpio Black 500GB hard drive that I'm using as an external and I couldn't be happier with it. :) I also have it plugged into my USB 3.0 ports.

NCIX sale? lol

Haven't seen the 750GB go on sale yet. I wouldn't mind as an upgrade down the road but I think I'd rather go from 500GB to 1TB although I haven't seen any 2.5" drives.

Wish they made the Scorpio Black in PATA / IDE as I have an older laptop that begs for a faster HDD.
