well the best hhd is the western digital caviar black 1.5tb yes it has bad reviews BUT thats because almost EVERY part has SOME bad reviews and the reason u c EVERY LAST hhd w/ bad reviews is cuz hhd's have much higher fail rates than other parts
Hi there! Welcome to the forums.
I'd say the optimal size/cost drive is this one right here: http://www.newegg.ca/Product/Product.aspx?Item=N82E1682... For $85, you're getting a decent 500GB hard drive.
While none may be 5 star, there a few things contributing to this.
-High drive prices due to floods
-Higher failure rates than other devices
Given the prices of hdd's smaller is better right now. So a 500gb is the sweet spot. If you are not going to use an SSD for the boot drive and instead stick with one Hdd for boot and storage then you need the best possible. The WD Black series is that. Longest warranty and as close to industrial strength as you can buy.
