RAID 0 seems to me as just asking for trouble, and really not worth the risk, especially in home use scenarios and if you're talking of SSDs.

If the supposedly failed drive seems to have raised from the dead, sure, you could use it as backup. Not in a RAID configuration, but just occasionally making a backup, maybe automatically. There's a lot of backup software out there that can make full images, so if anything goes wrong you just boot from the backup drive and it's all the same (be aware that just copying system files over won't allow you to do that, especially since that most probably won't include the hidden boot partition at all), and even the included system image backup tool in Windows generally works well enough and can be used off a running system (on Win 10+, look for "Backup and restore (Windows 7)", deprecated but still there and functional). For everything else, on the other hand, the robocopy tool in Windows really does a pretty good job, just updating what's changed, and can be automated too. But it's a command line tool, so can take a bit of learning to use properly.

just use the drives normally RAID is really only good for if you are running a company and need redunancy and its better with more then TWO drives but my experience with RAID and such is limited.

but my old man advice (being 42 lol) is just use the drives normally, and perhaps invest in a external SSD for back up.

Weird that a "gaming" laptop comes with Raid 0 setup. What da heck? As if modern PCI ssd's need a bit more performance O.o
Have we gone back to 2010?

If you don't want to copy every stuff from the C:\ drive to the D:\ you can also install games (and programs) directly on the D:\ drive itself. If using GOG offline installers just point them to the D:\ drive, create a folder named "Games" or similar to avoid clutter.
This is the way I have my desktop computer setup, most games goes to the secondary D:\ drive (even Steam ones).

edit - as a direct respose to your question:
Yes you can. If you should it's up to you but as mentioned above, that is how I have my main desktop setup. There's pretty much no downsides.

ADATA, yikes!

Huh, when you pointed out the brand and I did a search, I found that there may be firmware issues with those in laptops and an update should fix them: https://support.hp.com/ie-en/document/ish_12634449-12634493-16

If you mean creating a Windows 11 USB installation media with the MS Media Creation Tool, 8GB USB memory stick is enough.

I was fighting getting Windows 11 updates in on one laptop earlier this week (a relative). I ended up reinstalling the whole Windows 11 from scratch on it (using the Media Creation Tool) because for some reason its web camera had stopped working as well and I just couldn't fix it either, no matter what "reinstall the driver" etc. I tried. Resetting Windows 11 to factory defaults didn't help, web cam was still kaputt and those updates just wouldn't install.

The odd fhing is that:

1. The first time I reinstalled Windows 11 from scratch, the same updates would still fail even on the fresh installation.

2. I decided to try also Windows 10 from scratch... and even it failed with some updates! Not even installing them manually by downloading the update .msi files from MS Update Catalog page helped, same problem as with Windows 11, it would just say "something unexpected happened, reverting back to earlier...".

3. I checked the hardware, ran CrystalDiskInfo to check the SSD and also tested RAM and ran some full ASUS system checker, everything ok.

4. In Windows 10, I finally tried some extra instructions I hadn't yet tried where I needed to restart or start two Windows services in the safe mode, one was the Windows Update service itself and the other was some "Downloader service" if I recall correctly, which was stopped for some reason.

Not sure if it was a coincidence, but after that I finally seemed to be able to proceed with the updates, both in Windows 10 and the same installation updated to Windows 11. It is also a possibility that there was some generic problem with those updates that MS just happened to fix while I was troubleshooting it at my end.

I reinstalled Windows 11 from scratch once more and then everything finally worked, even the latest preliminary feature update got installed and the webcam was working too now (I was suspecting there was an actual hardware problem with the camera, but apparently not...).

I used two days for that so if I had used OFG's techie's pricing, it would have cost maybe two thousand dollars. I did it for free (for a relative).

Sometimes the life with Windows is not so easy after all... The most irritating thing was how little help Windows feedback is "something went wrong", yeah damn helpful. There was some error code but when I googled for it, the suggestions were very generic that pretty much anything could have caused the problem, starting from running out of hard drive space during the update etc.

Then again yeah I am currently troubleshooting also some crackling audio problems in one of my Linux laptops.

For some reason the Dell laptops I've used and am using usually seem to ship with "RAID On mode" for the SSD.

It was the reason why I couldn't e.g. install and dualboot Linux on those laptops (they have only one SSD in them, both Windows and Linux on the same drive on different partitions). The setting had to first be changed to ACHI mode in the BIOS/UEFI settings, which unfortunately also meant Windows needed to be reinstalled I think, or at least it wouldnt't boot anymore if you just switched the mode to ACHI.

I googled what's the benefit of the RAID On mode, and apparently it can offer a bit better performance in some situations, but it is not really recommended for e.g. home use. So my two Dell laptops are now running in ACHI mode, and at least Windows 11 + Linux work just fine without issues on them, side by side.

Precisely. Assuming that disassembly of the laptop in question is fairly simple, I would definitely recommend the immediate replacement of these drives with Samsung analogs. The monetary cost may be relatively high, but, the provided peace of mind is more than worth the price.

I prefer Crucial/Micron, but to each their own. ;)
