I've been looking at the Samsung HD502HJ
Which is more quiet and more reliable? The Samsung HD502HJ or the WD Caviar Blue WD5000AAKX
I won a HD502HJ, and its not silent, but its very quiet at least to my standards, more than any hdd i have used, i have no experience with the WD Caviar blues to compare it. Its been runing for almost a year now, and no issues, i bought it as the Samsung F3 was one of the fastest hdd of its time rivaling WD blacks, i believe is a single platter so my decision went to it because of this, and i dont regret it, its been a good drive.
One alternative is could be go into 2.5 drives, since size is no importance to you, i have a Hitachi 7k500 on my laptop, and also very quiet drive (not silent), probably more than Samsung.
