![]() I couldn’t say.Ĭhris Mellor: They’re a lovely bunch of people.Ĭhris Evans: Good. Maybe you didn’t write anything about them at all. A lot of startups.Ĭhris Evans: Yes and doing lots of writing about it I guess. You didn’t make that one Chris because you were off going gallivanting in the US again, one of your trips.Ĭhris Mellor: I loved the IT Press Tour meeting. And actually, we didn’t really make any serious predictions. It is 2020 and we did our sort of recap of the success or not of our predictions a couple of weeks ago. You’ve just highlighted the fact, Martin, that it is the start of the new year. That’s a bit naughty of me, isn’t it?Ĭhris Evans: Yeah, probably. Martin: If you’ve got an French listeners, they can confirm or deny this.Ĭhris Evans: I lived in France for three years and I don’t honestly remember what you did. Martin: Supposedly in France, it’s acceptable to wish people Happy New Year until the end of January. Happy New Year everybody.Ĭhris Evans: Well we’re a days in aren’t we? How are you doing?Ĭhris Mellor: Hello, Chris. Speaker 1: This is Storage Unpacked, subscribe at .Ĭhris Evans: Hi, this is Chris Evans recording another Storage Unpacked podcast and I’m joined by Martin and Chris this week. 00:34:05 – Is hyperscaler IT diverging from enterprise IT?.00:31:10 – Containerisation – moving from x86 to ARM.00:30:00 – ARM servers could be popular in 10 years’ time.00:27:35 – Obligatory mainframe reference!.00:26:34 – Liqid could be an interesting composable solution.00:23:20 – What has happened with composable systems?.00:19:30 – Migration to SSDs wasn’t a big architectural change.00:16:55 – Has much happened in 12 months – 10 years?.00:14:35 – Is the physical reliability of tape good or bad?.00:13:20 – Are hard drives the new tape?.00:11:40 – 20TB+ hard drive capacity, what’s next?.00:10:40 – Enmotus have developed a hybrid SSD.00:02:30 – Kioxia fire in the clean room.00:01:40 – Storage predictions only please!.Part II of this recording will follow next week. Similarly, ARM processors look to be on the cusp of data centre relevance. The technology is in the early days and maybe not ready yet for mass adoption. Composability enables servers to be dynamically built from their constituent parts. The final part of the discussion turns to systems and composable systems in particular. Will 2020 be the year we see multi-actuator take off?ĭoes old media continue into decline as the new tape? Could punched cards make a comeback? We think it’s unlikely. Hard drives are at 20TB and growing, but suffering the challenges of throughput. QLC increases in layers, while PLC (penta-level cell) flash is being mooted as increasingly more practical. This trend is expected to continue, but what micro-level advancements are being made? At the macro level, capacities continue to grow for SSDs and HDDs year on year. We should point out that this is only for enterprise storage and not a forecast on the world in general! Now read: Teraco gets R2.This week Chris and Martin are joined by Chris Mellor for what is turning into an annual look at storage technology for the year ahead. The reporting period is from 1 April 2013 through 31 December 2020. The table below shows the reliability of hard drive models Backblaze had in service as of 31 December 2020. The most reliable hard drives for 2020 are listed below, along with their annualised failure rates calculated from their performance during the quarter. “In other words, whether a drive was old or new, or big or small, they performed well in our environment in 2020,” Backblaze said. The company attributed this improvement to the better performance of older drives and the addition of over 30,000 larger drives with better reliability in its environment. “The Annualised Failure Rate (AFR) for 2020 dropped below 1% down to 0.93%,” Backblaze said. These drives are included in its report for completeless only. The company tested a total of 162,299 hard throughout 2020, equating to a total of 51,267,791 days worth of hard drive operation across all products.īackblaze noted that the annualised failure rate for drives with less than 250,000 drive days is not reflective of their performance due to the lack of data. Reliability was measured as an annualised failure rate, calculated using the number of drive failures relative to the number of active drive days for each disk.īackblaze recorded the number of failures for each hard drive from 1 January to 31 December 2020, extrapolating an annualised failure rate based on the number of days each drive was active. The company compiled the report from data on the active hard drives used in its daily operations – including Seagate, Toshiba, and HGST. Cloud backup provider Backblaze has released its hard drive reliability statistics for 2020.
