It looks like this drive was just introduced recently, and may not be on the market just yet.

Notice however that it only spins at 4200 RPM, so it won't be a good drive if you need speed for video editing or something like that.
 
good enogh for most people but. you will not notice a speed difference between a 5400rpm and 4200rpm HDD if all you do is email, internet, word process et al. 4200rpm and 7200rpm you will notice a difference however. :)
