34 : * Note that in this data:
35 : * - Disks all passed the load-testing and have made it to production,
36 : * and then Dead On Arrival (DOA) failures are excluded.
37 : * - Disks that are predicted to fail by BackBlaze are removed before
38 : * they really fail, not counting as a failure.
39 : *
40 : * The following tables are computed using the data from 2014-02-14 to 2014-12-31
41 : * because it's the period when more SMART attributes were gathered.
42 : *
43 : * In this period there are 47322 disk seen, with 1988 removed because failed,
44 : * and with 4121 removed because predicted to fail.
