![]() ![]() It might be some attempt along the supply chain to boost monthly or quarterly top line at the expense of profits, I don't know. But for reasons nobody at Backblaze can figure out, sometimes a bunch of new drives appears randomly at a really good discount price, then returns to the original price the next month. Most of the time we are literally paying about retail, maybe a 3% - 5% discount for buying in bulk orders of over 10,000 drives. But don't think we have some magically huge discount or anything. We would expect the Seagate 3TB drives to follow the bathtub-shaped failure rate curve described in our study on hard drive life expectancy. Electricity is one of our largest datacenter costs, so we keep an eye on that also.īut to answer your very first question, unfortunately we cannot release the price we paid for the drives due to the vendors requesting we don't disclose prices. Also, most drives seem to take about the same amount of electricity unrelated to how many TBytes are contained inside, so double the drive density is like saying it takes half as much electricity over its 4 - 5 year lifespan. Now, total cost of ownership includes the physical space rental so more dense drives can be more expensive per TByte in raw drive cost because we can make some of that back up in physical space rental. If a drive fails 1% more often but is 2% cheaper in total cost of ownership, we buy that drive. For Backblaze, we just feed it back into the cost calculation. Thank you, that is EXACTLY the correct way to look at the failure statistics! So many people seem to sort the list by failure rate and think no matter what the cost, the lowest failure rate wins. Backblaze is back again with a new update on its hard drive and SSD failure rates for the 3rd quarter of 2021.As of September 30th, 2021, the company had 194,749 drives spread across four data. If they survive past a year, there’s a good chance that they’ll make it the expected lifespan.īackblaze considers it a hard drive failure when the drive will no longer spin or connect to the computer’s operating system, will not sync with other disks, or displays signs highly correlated with imminent failure.> Do BB publish pricing of what they paid for drives?. During this quarter 4 (four) drive models, from 3 (three) manufacturers, had 0 (zero) drive failures. In addition, the Q1 2020 AFR is significantly lower than the Q1 2019 AFR which was 1.56. That is the lowest AFR for any quarter since we started keeping track in 2013. Hard drives usually fail at the beginning of their lifetimes or at around 4 years old. The Annualized Failure Rate (AFR) for Q1 2020 was 1.07. Gleb Budman, Backblaze’s CEO, describes the way hard drives fail as a bathtub curve. Backblaze says they’d like to order more of these, but the company isn’t able to take orders that large. HGST’s drives also fail at a decreasing rate year over year, with a rate just over one percent. The drives least likely to fail were made by HGST, a hard drive company owned by Western Digital that isn’t targeted at a consumer market. In terms of the hard drives that are most likely to fail, Backblaze’s data outs Western Digital, which had a 2016 failure rate of 6.55 percent. (It’s also worth noting that the sample size in 2016 also doubled from 18,017 drives to 36,863 drives.) The largest improvement was by Seagate between 20, where the rate of failures dropped from 10.68 percent to 3.48 percent, more than half. At the end of 2018 Backblaze was monitoring 104,954 hard drives used to store data. Year over year, the failure rate decreases. 2018 Hard Drive Failure Rates: What 100,000+ Hard Drives Tell Us. ![]() This isn’t a sweeping investigation of every hard drive manufacturer on the market, but the independent data of one company that buys hard drives in bulk, and buys from the biggest players in the market.Īt first glance, hard drive technology seems to be improving. The company’s latest analysis of more than 60,000 hard drives details which brands of drive fail with greater frequency. The shelf life for the average drive is about four years, according to research by data storage company Backblaze. The table below shows the failure rates for the hard drive models we had in service as of June 30, 2017. ![]() We may earn revenue from the products available on this page and participate in affiliate programs.
