Do remember that there are only 2 kinds of HDs--those that have failed and those that will.
Very well put.
My perception has been that hard drive longevity is pretty much unpredictable, and any correlation between the likelihood of failure and the brand of the drive will vary over the years.
Around 10 or 12 years ago IBM manufactured a widely used series of drives called the Deskstars, which failed so frequently that they were widely referred to as the IBM Deathstars. I had one of them, and it lasted about 5 months. Shortly afterwards IBM got out of the business, selling that division to Hitachi.
BTW, IMO one of the ultimate examples of the famous saying popularized by Mark Twain, that there are "lies, damn lies, and statistics," are the MTBF (mean time between failure) specs that are often provided by hard drive manufacturers. Those numbers are commonly on the order of a million hours or so, which is about 114 years. But what the number really means is that if a very large number of drives are run at the same time, then on average one of those drives will fail for each million cumulative hours of operation of all the drives. In other words, the statistic doesn't take into account the failure rate increase that will occur as the drives get older.
