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.
they currently have it do a backup immediatly on power loss (which is a
safe choice as the contents won't be changing without power), but it then
powers off (which is not good for startup time afterwords)
