It looks like shit and feels like shit. I thought it was native tbh... given how chunky UI is. Looks like GDI programming to me. Or they took design from Android 2 and ported it to Desktop.
I haven't use any alternatives, and haven't developed with electron, but I know that there are another alternative -- Tauri. It also uses web-view. It's built in Rust and allows apps to be developed in JS (providing JS api) and in Rust.
What I can say -- JS support won't be cross-platform, like we have with NodeJS in electron. Special debug per platform might be required.
But AFAIK real RAID don't perform CRC, thy rely on drive to report bad sector. In case if on one drive data got corrupted, it would return data from one drive or another. In case of mirroring. If we aren't talking about RAID 6 I think.
Suggestion at the end:
Wouldn't it destroy GoogleBot (and other search engine) those making your site delisted from Search?
