I've had good experience with Samsung F3 or F4 and the latest Seagate Barracuda.
In preference I would probably go for the latest Barracuda series than the Samsung as the samsungs can get noisy. The performance is pretty much the same, and reliability also very much the same (now).
Reliability never seems to be great for any consumer level hard disks anymore, such as buggy firmware resulting in complete data loss and all sorts, which is why I pay a little less attention to reliability statistics now because I make sure there is a tried and tested backup solution implemented!
i.e., my train of thought goes that I'd rather get 2 disks with moderate reliability and have them mirrored (not necessarily in the RAID sense) rather than 1 disk with a claimed better reliability.
