ps3 Hard drive upgrade choice

I've narrowed down to two potential drives.

theToshiba MQ01ABD075 750GB 2.5 inch Internal Hard Drivewhich goes for £58 &only came out this year.

& the more conventialWestern Digital Scorpio Blue 500GB 5400 RPM (£47),which people have been doing for years.

Which one offers better performance? & a better deal?

Also if there's any drive better than these two, min 500 gb, around £40- £60 & reliable, please do tell, thanks.

i have western digital in my ps3
works very well
wouldn't trust toshiba or anything above 500GB
but that's my opinion
