Thank you all for helping debug this issue.
It appears the initial suggestion was AI-generated, based on the style and format in the original post that referenced "Can I use a Fedora Live CD to mount...". While it was helpful to some extent, the proposed solution ultimately did not work as expected due to several limitations. Fedora LiveCD/USB environments come in various versions, and commands can behave differently depending on the specific combination of version and environment used.
For example, the following command failed when executed in the Fedora 42 Live environment (booted via USB media):
sudo dnf install dmraid
The failure message was: "failed to resolve the transaction" and "no match for argument dmraind:"
To provide additional context: Fedora 42's Live CD/USB environment does not include `dmraid` by default, nor does it allow installation via the above command. A subsequent search within the booted environment, executed as follows:
sudo dnf search dmraid ...returned: "no matches found."
The search was performed after the install command failed, simply to confirm whether the `dmraid` package might already exist in the environment?�but it does not.
So, since this approach appears to be a dead end (at least thus far), are there any alternative methods to non-destructively test RAID 0 read performance?
For reference, when testing in the native environment (Windows 11), the issues are consistently related to read commands, irrespective of hardware connection configurations. However, write commands only produce at RAID 0 performance thresholds when one SSD is connected directly to the CPU bus and the other is on the chipset bus. These findings have been consistent across all tested configurations. |
im really am sorry, i literally asked the chatbot that in next prompts and it assured me that fedora should be the most straight forward to do that and wont need internet connection. Personally i just use arch

below are the results i get on a single kc3000,nv2 drives:
> sudo hdparm -Tt /dev/nvme0n1p4
/dev/nvme0n1p4: Timing cached reads: 57590 MB in 1.99 seconds = 28908.02 MB/sec Timing buffered disk reads: 7560 MB in 3.00 seconds = 2519.50 MB/sec mm@desktop ~ > sudo hdparm -Tt /dev/nvme1n1p5
/dev/nvme1n1p5: Timing cached reads: 58770 MB in 1.99 seconds = 29503.06 MB/sec Timing buffered disk reads: 8126 MB in 3.00 seconds = 2708.63 MB/sec
