That is good advice. I bought six 1TB drives at the same time a few
years ago and received drives with consequtive serial numbers. They
were all part of the same array, and they all failed ("click of death")
within a six hour timespan of each other. Luckily I noticed the
clicking right away and was able to get all the data copied to another
array within a few hours, before they all died.
