![]() QNAP Integrates Backblaze B2 Cloud Storage to NAS Servers - 12:12 PM Of that number, there were 2,380 boot drives and 129,959 data drives. ![]() Of that number, there were 2,271 boot drives and 140,059 data drives.īackblaze Shares Hard Drive Stats for Q1 2020 - 02:58 PMĪs of March 31, 2020, Backblaze had 132,339 spinning hard drives in their cloud storage ecosystem spread across four data centers. The chart below shows the lifetime annualized failure rates of all of the drives models in production as of December 31, 2020.īackblaze Outs Q2 2020 Hard Drive Stats for 142,630 Spinning HDDs - 02:33 PMĪs of June 30, 2020, Backblaze had 142,630 spinning hard drives in our cloud storage ecosystem spread across four data centers. In other words, whether a drive was old or new, or big or small, they performed well in our environment in 2020. Finally, the 12TB drives as a group had a 2020 AFR of 0.98%. At the other end of the size spectrum, we added over 30,000 larger drives: 14TB, 16TB, and 18TB, which as a group recorded an AFR of 0.89% for 2020. To start, the older drives: 4TB, 6TB, 8TB, and 10TB drives as a group were significantly better in 2020, decreasing from a 1.35% AFR in 2019 to a 0.96% AFR in 2020. So why was the 2020 AFR so low? The answer: It was a group effort. The AFR for 2020 dropped below 1% down to 0.93%. The Annualized Failure Rate for 2020 Is Way Down The data for each year is inclusive of that year only and for the drive models present at the end of each year. The chart below compares the AFR for each of the last three years. Comparing Hard Drive Stats for 2018, 2019, and 2020 While each drive model has only been installed for about two months, they are off to a great start. ![]() The new Toshiba 14TB drive (model: MG07ACA14TA) and the new Toshiba 16TB (model: MG08ACA16TEY) were introduced to our data centers in 2020 and they are putting up zeros, as in zero failures. As a group, they totaled 13,596 drives and amassed 1,783,166 drive days with just 46 failures for an AFR of 0.94%. These drives ranged in size from 12TB to 18TB and were used for both migration replacements as well as new storage. Five of these models are listed in the table above and one model had only 26 drives, so it was not listed. There are six Seagate drive models that were new to our farm in 2020. To that end, we qualified nine new drives models during the year, as shown below. We had a goal at the beginning of 2020 to diversify the number of drive models we qualified for use in our data centers. The AFR for 2020 for all drive models was 0.93%, which was less than half the AFR for 2019. The 6TB Seagate model was followed closely by the perennial contenders from HGST: the 4TB drive (model: HMS5C4040ALE640) at 0.27%, the 4TB drive (model: HMS5C4040BLE640), at 0.27%, the 8TB drive (model: HUH728080ALE600) at 0.29%, and the 12TB drive (model: HUH721212ALE600) at 0.31%. This model was also the oldest, in average age, of all the drives listed. We present the models with less than 250,000 drive days for completeness only.įor drive models with over 250,000 drive days over the course of 2020, the Seagate 6TB drive (model: ST6000DX000) leads the way with a 0.23% annualized failure rate (AFR). There is not enough data over the year-long period to reach any conclusions. The data for all drives, data drives, boot drives, etc., is available for download on the Hard Drive Test Data webpage.įor drives which have less than 250,000 drive days, any conclusions about drive failure rates are not justified. The 231 drives not included in the list above were either used for testing or did not have at least 60 drives of the same model at any time during the year. ![]() This leaves us with 162,299 hard drives in 2020, as listed below. For our evaluation, we remove from consideration 231 drives which were used for testing purposes and those drive models for which we did not have at least 60 drives. Of that number, there were 3,000 boot drives and 162,530 data drives.Īt the end of 2020, Backblaze was monitoring 162,530 hard drives used to store data. In 2020, Backblaze added 39,792 hard drives and as of Decemwe had 165,530 drives under management.
