Is it really the case that nobody has benchmarked Chromium build on a Windows DevDrive vs. a regular NTFS partition?

I don't know what brain damage has occurred here, but if this isn't a measurement error and I actually run out of space on this ReFS devdrive, I'm uninstalling windows

The X: drive also has a DevDrive partition D: which will need to be shuffled around somehow. I'm fine with 2TB on the OS drive but X: drive needs to be waaaaayyy bigger so I can substantially expand my DevDrive partition.

Interesting got Azure Devbox onboarded to Windows Insider dev channel via Intune and DevDrive up and running, relocated nuget/npm/tmp/docker caches.
Only took a couple reboots and one gpo setting 😎
Don't know if it's faster yet but kinda like having disposable dev bits on its own drive.

One day your #DevDrive is fine. The next, all you get is ReFS claiming to be write‑protected, and laughing at your pitiful attemps at takeown and icacls.
And as usual, there's a fix at the end of what turned out to be another ridiculous journey in the #Windows'land

So I created a windows 11 build VM and then two scalesets. During the scaleset provisioning a disk is attached, this is the build disk.
One one scaleset I formatted the build disk as a DevDrive instead of NTFS. This took 15m off my 2hr product build.
For fuck all.
Nice one, DevDrive 👍

I briefly looked into those but was too scared to try it. I'm worried that'll just make future migrations more painful. 😅
I'm already using a Win11 DevDrive partition on one of my drives to improve my compile times and that's adding enough complexity for me already lol

wenn man in Win11 ein DevDrive vergrößern will, dann hat man da einen Link "hey du musst zuerst die virtuelle Disk vergrößern". Und auf der Seite ist dann ein Powershell-Befehl den man ausführen muss. Danach kann man das Drive dann vergrößern.
Warum führt Win den Befehl nicht einfach selber aus?

@scott.hanselman.com do you have any guidance for configuring MS Defender for Endpoint on Windows dev machines? We have CPU usage of 10-30% when doing nothing and "Antimalware Service Executable" takes 75% cpu while compiling. We tried excluding folders and DevDrive - nothing seems to work.

Node.jsの開発自体はWindowsでもできるのだけど、ファイルシステムが遅くて。新しく出てきたDevDriveには期待しているけど、ReFSがリムーバブルメディアでは動かないということなので試してみようにもハードルが高い。
