What I meant to say here is that using external HDD as opposed to DVDs is expensive.
OK.
And yes, most DVDs are DVD-R format -- but that is not a problem because you can use the same DVD to install the offline Wikipedia from one school to another.
What I meant by single usage what that the medium is so fragile that you can't use it twice. Mainly because of dust but that depends on the environnement.
Main advantage I see to DVD is that it's by far the cheapest option if your content fits on it.
