BackBlaze is again with its new exhausting force reliability file: Since our ultimate file for Q1 2017, we have added 635 additional hard drives to bring us to the 83,151 drives we’ll focus on. We’ll start our assessment through having a look on the statistics for the duration of April 1, 2017 via June 30, 2017 (Q2 2017). […] When having a look on the quarterly numbers, take into account to seem for the ones drives with a minimum of 50,000 force hours for the quarter. That works out to about 550 drives operating all of the quarter. That’s a just right pattern dimension. If the pattern dimension is under that, the failure charges will also be skewed according to a small exchange within the collection of force screw ups.
Editor’s observe: In brief: exhausting drives from HGST, a subsidiary of Western Digital, and Toshiba had been way more dependable than the ones from Seagate.
