...and many used Seagate drives have been resold as new in the last 3 years. They were used for crypto mining and then had their SMART parameters wiped back to "new" 0 hours usage. https://www.heise.de/en/news/Hard-disk-fraud-Increasing-evid...
Is crypto mining a high storage IO operation? I always thought it was hard on CPU and RAM, but not on disk IO.

> more content than most people watch in a lifetime The average person watches more than 3 hours of TV/video per day, and 1 gigabyte per hour is on the low end of 1080p quality. Multiply those together and you'd need 1TB per year. 5TB per year of higher quality 1080p wouldn't be an outlier.
Holy crap! I watch like, maybe a couple of movies a month and two or three miniseries a year? Is that including ads too? And sports/news? EDIT: Wait, are these "average person" or "average American?"

"In a survey conducted in India in January 2022, respondents of age 56 years and above spent the most time watching television, at an average of over three hours per day."

For china I'm seeing a bit over two and a half hours of TV in 2009, and more recently a bit over one and a half hours TV plus a bit over half an hour of streaming.
Yes it includes ads, sports, and news.
Personally I don't watch a lot of actual TV but I have youtube or twitch on half the time.

Take these stats with a grain of salt. I am becoming more and more convinced that hard drive reliability is linked to the batch more than to the individual drive models themselves. Often you will read online of people experiencing multiple failures from drives purchased from the same batch. I cannot prove this because I have no idea about Blackblazes procurement patterns but I bought one of the better drives in this…
Well to me the report is mostly useful to illustrate the volatility of hard drive failure. It isn't a particular manufacturer or line of disks, it's all over the place. By the time Backblaze has a sufficient number of a particular model and sufficient time lapsed to measure failures, the drive is an obsolete model, so the report cannot really inform my decision for buying new drives. These are new drive stats, so not…

IME heat is a significant factor with spindle drives. People will buy enterprise-class drives, then stick them in enclosures and computer cases that don't flow much air over it, leading to the motor and logic board getting much warmer than they should.
Heat is also a problem for flash. If you care about your data, you have to keep it cool and redundant.
The NVMe drives in my servers have these little aluminium cases on them as part of the hotswap assembly. They manage the temperature differential by using a conductive pad for the controller, but not the flash.

One of these blogs literally told us that enterprise drives were no better. https://www.backblaze.com/blog/enterprise-drive-reliability/
Seems outdated - a lot of the drives in the 2024 statistics are enterprise drives - so they are using them

> need to change to a more-than-64-bit architecture Perhaps we don't need a single flat address space with byte-addressable granularity at those sizes? I wonder how an 8 bit byte, 48 bit word system would have fared. 2*32 is easy to exhaust in routine tasks; 2*48 not so much.
> Perhaps we don't need a single flat address space with byte-addressable granularity at those sizes? History is filled with paging schemes in computers (e.g. https://en.wikipedia.org/wiki/Physical_Address_Extension ). Usually people do this initially as it allows one to access more space without requiring a change of all software, it is an extension to an existing software paradigm, but once the CPU can just address…
My pondering is less "why such a large address space" and more "why such a large native word size"? Extra bits don't come without costs.
As long as I'm asking ridiculous questions, why not 12-bit bytes? I feel like a 12/48 system would be significantly more practical for the vast majority of everyday tasks. Is it just due to inertia at this point or have I missed some fundamental observation?
Google sells 2TB of space on Google drive for $10/month. I'm looking to move my data elsewhere. Can anyone recommend a European based alternative with a roughly similar cost?
OneDrive space (through MS365 single or family licence) works out much cheaper in my country. I'm sure in the EU it is GDPR-compliant. YMMV but OneDrive has been improving a lot. Their web photos browsing is comparable to Google Photos these days.
> I'm sure in the EU it is GDPR-compliant.
Sure ain't, especially not in Germany with the BDS.

I assume by "cycle" they are referring to mtbf/afr
I am reasonably confident that "time for the cycle to repeat" is the cycle of purchasing a new drive and moving to it. Whether that's right or wrong, when I talked about 5% failure chance per cycle that's what I meant. And 5% is probably an underestimate.

Ahh. That % would depend on fleet size. AFR should be under 1% for most drives.
