Is there a way to save responsive images to a different disk?

Hey all, greetings!

In the project I'm working on, there are many galleries with many photos. It's expected to have ~200 images in a single gallery, and they will be shown in a grid pattern. Since this will always be the case, I decided to simplify the responsive image calculator a bit, like the following:

class FileSizeOptimizedWidthCalculator implements WidthCalculator
{
    /**
     * @return Collection<int, int>
     */
    public function calculateWidthsFromFile(string $imagePath): Collection
    {
        $image = ImageFactory::load($imagePath);

        $width = $image->getWidth();
        $height = $image->getHeight();

        return $this->calculateWidths(0, $width, $height);
    }

    /**
     * @return Collection<int, int>
     */
    public function calculateWidths(int $fileSize, int $width, int $height): Collection
    {
        return collect([
            $width,
            420,
        ]);
    }
}

This is working great, I have only a single 420px thumbnail image, which is what is used in the gallery. I then use fancybox to open the full-size image when the user clicks on it.

All good, but my question is: Is there a way to save this thumbnail on a different disk? The actual images are saved in S3, since there are many, but the thumbnails are very small in size (~30kb) so I think it would improve performance by saving them in the same disk as the application, which runs on a fast NVMe SSD storage.

Is this possible? If so, how?

Thank you all!
