Hi. I have to build 2 computers. One for selling and one for me. I have 2 hdd here that are flawless: Western Digital WD3200AAKS 320GB 7200RPM 16MB http://www.newegg.ca/Product/Product.aspx?Item=N82E16822136074 and Samsung Spinpoint SP2504C 250GB 7200RPM 8M http://www.newegg.com/Product/Product.aspx?Item=N82E16822152025 In theory the WD is faster due to higher cache and have more capacity. The Samsung is more silent. Which one is more reliable in long term? I am never using more than 150GB in a hdd so capacity does not really matter. Thank you guys.
