Huawei may have used a very clever trick to make hard disks use less power — spin-on-demand disk drives may well compete with tape on performance, but at what cost? (www.techradar.com)

“but at what cost?”

GolfNovemberUniform@lemmy.ml on 18 Mar 2024 13:01 next collapse

Idk why nobody made it before. If you have 2 drives you usually only use the second HDD for data storage and sometimes games. This feature should have been there for years already (not as the default though cuz performance)

it’s definitely one of those obvious in retrospect things

GolfNovemberUniform@lemmy.ml on 18 Mar 2024 13:05 collapse

Could you explain what you mean?

yogthos@lemmy.ml on 18 Mar 2024 13:43 collapse

I mean that once the idea is demonstrated, it’s not actually that complicated. But seems like nobody tried doing it until now. A lot of innovation seems very obvious in retrospect once somebody does it.

Oh ok now I understand. I thought you meant that there was an obvious reason not to use this technology in the past. My English is really bad

yogthos@lemmy.ml on 18 Mar 2024 14:15 collapse

no worries

We have. Spinning down disks not being accessed has been a thing for decades.

But it’s rarely used, because even if you the user aren’t reading or writing files, all the background systems are still using the disk. And spinning up and down is more west and tear on a drive than constant spinning.

Background systems using secondary drives for no obvious reason is suspicious behavior

Gabu@lemmy.ml on 18 Mar 2024 18:57 collapse

It’s fairly standard behavior

GolfNovemberUniform@lemmy.ml on 18 Mar 2024 22:15 collapse

Standard ≠ good

Gabu@lemmy.ml on 18 Mar 2024 23:12 collapse

Completely irrelevant, nobody argued for or against that.

Never glanced at Windows power options, eh?

GolfNovemberUniform@lemmy.ml on 18 Mar 2024 14:22 collapse

I don’t use Windows much and I don’t remember such feature

Never configured udisks, eh?

GolfNovemberUniform@lemmy.ml on 18 Mar 2024 14:33 collapse

What is udisks? I’ve only heard of gdisk or whatever the name of that industry standard Linux partition manager thing is

If only that comment contained a link explaining exactly what it is…

I saw the link. I asked that to show that I’ve never seen that program before

I got a drive over 10 years ago that had some very aggressive power management by default. It would park the heads and spin down less than a minute after the last access. It was so bad that it would kill the drives within a couple of years if you didn’t disable it. I found out about it a couple weeks after getting the drive and it already had more load/unload cycles than a disk that’s been in normal use for years.

It was a problem with early WD green drives IIRC. The power management was exceptionally aggressive and caused massive issues when put in to any RAID-like set up. You could override it though generally.

Huawei was also smart in making EROFS, which later got integrated into Linux kernel. It is way better than F2FS (Google) or any other filesystem made on Android.

neat
