If you’re on Linux, I don’t think a windows VM is very useful for gaming? Most games run fine in proton, and the ones that don’t, probably don’t because of anticheat that will also refuse to run in a VM. I do know of one niche case that needed to be run in a VM until recently, that being SS13, but that was because of an engine dependency on IE for webviews.







One counterpoint - even with a weak speed to capacity ratio it could be very useful to have a lot of storage for incremental backup solutions, where you have a small index to check what needs to be backed up, only need to write new/modified data, and when restoring you only need to read the indexes and the amount you’re actually restoring. This saves time writing the data and lets you keep access to historical versions.
There’s two caveats here, of course, assuming those are not rewritable. One, you need to be able to quickly seek to the latest index, which can’t reliably be at the start, and two, you need a format that works without rewriting any data, possibly with a footer (like tar or zip, forgot which one), which introduces extra complexity (though I foresee a potential trick where the previous index can leave an unallocated block of data to write the address of the next index, to be written later)
