take a look at this ram based drive, specificly look at the numbers here http://techreport.com/articles.x/16255/9 they are about as much above the X25-e as the X25-e is above normal drives.
They're so close to having a killer product with that one. All they need to do is make the backup to the CF card automatic once the battery backup power drops low (but not so low there's not enough power to do said backup) and it would actually be a reasonable solution. The whole battery-backed cache approach is risky enough when the battery is expected to last a day or two; with this product only giving 4 hours, it not hard to imagine situations where you'd lose everything on there.
