[Zope] Recommended Storage

Hi all, I've recently seen a corruption error in a FileStorage Zope installation. I've been able to recover all my data with no problems, but this causes some doubts to me. I'm working in a bigger application that will need databases of about 5-10 Gb. I prefer a slower and secure storage than a faster and more unsecure one. Reading this ZODB Storages comparisson http://cvs.zope.org/ZODB3/Doc/storages.html?rev=1.5 it seems that DirectoryStorage is what I need. Any experiences about that ? Have anybody had some problem using DirectoryStorage over reiserfs ? Can I put my customers data there and sleep quiet :-) ? Thanks in advance Santi Camps
