To quote Jim: "I consider blob support in 3.8 to be somewhat experimental." [1]

You can use blobs in Plone 3 / ZODB 3.8. That's how we developed it
and then ironed out all the problems. But since we have more stable
versions of the software today, it doesn't make a lot of sense to go
back to the early development version. ZODB 3.9 has much more stable
blob support and direct support for RelStorage (without patches). If
you want to use either of those, you do yourself a favor by using the
latest stable versions.
