Even a table like this stored on disk will still have some parts in memory.
It will contain a hidden primary key index for starters.
Effectively this index will consume about 32 bytes of space in DataMemory
and around 16 bytes of memory in IndexMemory per row.
Also remember that you need the memory for the disk page cache which
by default is 64 MByte in size.
