I currently have a 1 TiB NVMe drive that has been hovering at 100 GiB left for the past couple months. I’ve kept it down by deleting a game every couple weeks, but I would like to play something sometime, and I’m running out of games to delete if I need more space.

That’s why I’ve been thinking about upgrading to a 2 TiB drive, but I just saw an interesting forum thread about LVM cache. The promise of having the storage capacity of an HDD with (usually) the speed of an SSD seems very appealing, but is it actually as good as it seems to be?

And if it is possible, which software should be used? LVM cache seems like a decent option, but I’ve seen people say it’s slow. bcache is also sometimes mentioned, but apparently that one can be unreliable at times.

Beyond that, what method should be used? The Arch Wiki page for bcache mentions several options. Some only seem to cache writes, while some aim to keep the HDD idle as long as possible.

Also, does anyone run a setup like this themselves?

    Back when SSDs were expensive and tiny they used to sell hybrid drives which were a normal sized HDD with a few gigs of SSD cache built in. Very similar to your proposal. When I upgraded from a HDD to a hybrid it was like getting a new computer, almost as good as a real SSD would have been.

    I say go for it.

    If it’s all Steam games then you could just move games around as needed, no need for a fancy automatic solution.
