but putting it on disk still requires an on-disk format. whether it's the 
database using a raw partition divided into pages and segments or files 
mapped out via inodes on disk, a format will still exist. it's the difference 
between chasing pointers around on disc versus a system where a data 
structure is queried for addresses and then a lookup (or lookups) are made on 
disk using those addresses into the on-disk format. again, depending on the 
characteristics of your data and how you access it, one system will likely be 
faster than the other. it's pretty obvious which one will take more RAM and 
disk space ;-)
