Its very much still needed and heavily utilised in the enterprise world. Volume size is usually the lowest priority when it comes to arrays, redundancy and IOPS (the amount of concurrent transactions to the storage) is typically the priority. The exception here would be backup and archive storage, where IOPS is less important and volume size is more important.

As far as replacing sectors goes, I’ve never heard of this and I might just be ignorant on the subject but as far as I know you can’t “replace” a bad sector. Only mark it as bad and not use it, and whatever was there before is gone. This has existed since HDD days. This is also why we use RAID - parity across disks to protect data.

Generally production storage will be in RAID-10, and backup/archive storage in RAID-6 or in some cases RAID-60 but I’m personally not a fan.

You also would consider how many disks are in the volume because there is a sweet spot. Too many disks = higher likelihood of total array failure due to simultaneous disk failures and more data loss in the event it does, but too few disks and you won’t have good redundancy, capacity or performance either (depending on RAID level).

The biggest change I see in RAID these days is moving away from hardware RAID cards and into software-based solutions like Microsoft Storage Spaces, md, ZFS and similar. These all have their own way of doing things and some can even synchronise the data with other hosts.

Hope this helps!

Putting his whole Sisyphussy into it

Thanks everyone! I think what I’ll end up doing here is posting the guide directly into lemmy as a condensed version of the full article, then link to the article which will have screenshots and more background.

I think that’s what got me too, I was expecting sci-fi and whilst I technically got it, I also got traumatised in the process lol. Credit where it’s due, it’s a fantastic movie because of the horrors I never imagined possible, but I watched it once more as an adult and that’s enough for me

I came here just to say this but wasn’t expecting to see it at the top of the thread, I’d seen scary movies before but holy hell this one chilled me to my core and even as an adult I still squinted when I watched it

Not that I’m advocating for Apple’s inexcusable behaviour, but as someone who’s worked in IT managing fleets of hundreds of Thinkpads (among others like Apple, Dell, Acer, HP), respectfully, they are far less reliable and durable than a MacBook. The only devices I had with higher failure rates than ThinkPads were Acer laptops.

They are certainly more repairable, but so are others like Dell and HP. Lenovo were one of the earlier manufacturers to pull some anti-repair moves such as soldering memory to the mainboard (on the Yoga models).

I think your statement is far more accurate in the days when IBM owned the ThinkPad brand, but unfortunately Lenovo have run it into the ground as far as quality goes.

All that said, I certainly hope we see more projects like Framework so that these big manufacturers can get some sort of reality check.

Nice try, detective
