The most best & most reliable hard disc drives?

[Phil]

OK, we've had a thread going for some time now about the prices of drives coming down.

Harv pointed out a 1.5 TB drive offer this morning which equates to just 5p (that's five pence) per GigaByte of hard disc storage space

So, given that HDD space is now REALLY cheap, who makes the best / most reliable hard drives?

Hitachi
Western Digital
Seagate
Samsung

Your thoughts???
