All HDDs are unreliable. Some more than others, but the only ones you should count on being more unreliable are the largest available sizes. For 2TB or less, today, the answer to your question is indirect: backup, backup, backup. A good series of drive will, from your perspective, with a small sample size, fail unpredictably as a bad series of drive. Data only on one storage device is data waiting to be lost.Guys have you seen any issues with the above drive like DOA or clicking noise..
