Databases are designed to handle arbitrarily large numbers of rows of structured data, where each datum is small and roughly the same size as all others of its kind. Storing arbitrary data in a BLOB column is tantamount to trying to turn the database into a file system. If you want a file system, use a file system.

Microsoft's been promising a database-backed file system for something like 15 years now. Maybe it's because they don't write software all that well up there in Redmond. Or maybe it's because this is one of those ideas that sounds good on paper but doesn't work out so well in practice. I'm betting on the latter.
