Summary: Generally, I have used Hitachi-IBM drives. I had one DOA. But, otherwise, no failures. Both Seagate drives that I tried, failed within a year. I tried the warranty on one of them. But, the drive I received back was DOA. Hopefully, WD will be better. But the reduction in choices is sad.
Pros: I have had the drive for about one month. It has worked well so far. Of course, my evaluation will change if it turns out to have a short life.
Cons: The quality level of hard drives seems generally to be at the three star level on average. That kind of quality is a disgrace to the industry and inhibits my purchases of hard drives
