Ross Lazarus, September 2016 This is a Kaplan Meier analysis of the BackBlaze hard drive reliability data, using all available data to end second quarter of 2016  from  https://www.backblaze.com/b2/hard-drive-test-data.html   .  Previous posts are  at  http://bioinformare.blogspot.com.au/2016/05/survival-analysis-of-hard-disk-drive.html  and  http://bioinformare.blogspot.com.au/2016/02/survival-analysis-of-hard-disk-drive.html   . I reran my scripts and got the plots shown below. It's taking a while to read all the data as there are now a very large number of drives spinning. A total of  41740623 rows were processed in about 35 minutes on my home desktop by the python script in the github repository. The new 8TB drives are performing the best of all - even better than the HGST and Hitachis - and way better than any of the earlier seagates. Hard to miss here - not so obvious in the report at Backblaze https://www.backblaz...
