Hard disk test 'surprises' Google:: 20 February, 2007
The impact of heavy use and high temperatures on hard disk drive failure may be overstated, says a report by three Google engineers.
The report examined 100,000 commercial hard drives, ranging from 80GB to 400GB in capacity, used at Google since 2001.
The firm uses "off-the-shelf" drives to store cached web pages and services.
"Our data indicate a much weaker correlation between utilisation levels and failures than previous work has suggested," the authors noted.
A wide variety of manufacturers and models were included in the report, but a breakdown was not provided.
