A probe-based data storage device comprising:
- a storage surface having an array of k*A storage fields, where k is an integer greater than or equal to 2;
- a probe array comprising k*A probes for writing data to respective storage fields;
- and
- control apparatus comprising k logical sub-devices (SD1 to SDk0) for controlling writing of data to respective logical sub-arrays (SA1 to SAk0), each of A storage fields, of the storage field array via respective logical sub-arrays, each of A probes, of the probe array, wherein each logical sub-device (SD1 to SDk0) comprises an apparatus for controlling writing of blocks of user data in the respective storage field sub-array (SA1 to SAk0).
