1. A mass storage system, comprising:

  • an array of non-volatile charge storage semiconductor memory cells organized into blocks that are erased prior to any new data being written therein and which individually have a capacity of storing multiple units of received data that individually include at least 512 bytes of data, a controller connected with the memory cell array and adapted to receive data with a logical address including a unique file identification and offsets of data within the identified file to program the received data at physical addresses within the blocks of memory cells, and which further operates to maintain a plurality of records of the programmed data for the individual files that identify groups of variable amounts of data making up the file, data within the groups individually having both contiguous logical offset addresses and contiguous physical addresses, wherein the individual records include at least a beginning logical offset address and a beginning physical address of the data within the group.
