The better soltion if the hardware has smart UPS backup. In that case the application has enough time to close database and backed up to persistent drive.

If you use ramdisk you need reliable hardware for.

You have chance to online backup of tables. You can found script for (lock for write, backup table to persistent, unlock for wirte). If you have less modification maybe this is better way to reliable backup.

If you have less modification in database think SSD (solid state) drive. This is persistent and has fast read capability. This is maybe the easyest solution.
