For one thing, no benchmarks I've seen of nvme SSD has shown them to be significantly faster if the BIOS is set to RAID, but I've not heard any thing for or against the power savings benefits of it.
So it's not the RAID that saves power, it's the [use of the] driver.
To be clear, I'm perfectly fine with a default setting of RAID -- but right now, they also lock you out of changing it back to AHCI.
What I think is reasonable is allowing users to change the setting back to AHCI (at their own risk, of course, as is the case with MOST settings in the BIOS). They should have done that all along, but instead, they artificially restricted it, locking us Linux users out by their own volition.
Because Internet forums. That's why. Search for "I can't install Windows 10 on my Lenovo Whatsyourface" and you'll get "Change this super secret setting to AHCI". And who's going to be doing those searches? Everyone, but specially people less computer savvy. The ones that know enough are here discussing Lenovo's decision.
Again, just to clarify: I'm not trying to defend Lenovo. What they did was a bad business decision, but maybe it was the lesser of two evils. Maybe they should've kept Intel accountable on this one - but who can argue with the only serious CPU manufacturer for laptops?
Lower performance for everyone or no drivers for Linux.
I take you know more than the article's author, in which case I'd be interested in reading your analysis as I'm not an expert.
There's a reason why that hasn't been done on any system in the past - because it's stupid and fake RAID drivers are notoriously buggy and require support from cloning and other low level software that gets used.
Yer, you're not an expert, or appear to know anything about hardware.
Also, the power saving stuff is bollocks. I never thought I would see the day when anyone would recommend using a bullshit fake RAID driver for power saving reasons.
I base my opinion on what experts call facts as I'm not a hardware expert myself.
