seems like a great price for a 1.5tb samsung to me! its 83p cheaper on the today only section so just click today only on the scan home page and scroll down to 'sata hard drive mix' and find it there.
this is a great drive to use as a secondary drive for storing music, movies, photos etc. i wouldn't recommend it for a boot drive though.
also great to use along with an SSD for boot :)
free delivery through hexus and av forums as usual
