Is it possible to have a bucket that uses only disk (or 90% of the time)?

Hi,

We have a use where we need to save a lot of documents, but we don’t care too much about performance of those documents. We’ve decided to create a new bucket and set very low RAM to it to force the bucket to save those documents into disk.

Is it safe to use a bucket in this way? We already have memory optimized buckets running just fine.
