Embodiments associated with configurable, repeatable, data generation are described. One example method includes manipulating a redundancy parameter that controls data redundancy in binary large objects (BLOBs) to be included in a generated data set. The redundancy parameters may control variations in repeatable variable length sequences included in BLOBs. The example method also includes manipulating a parameter(s) that controls custom designed sequences included in BLOBs. With the redundancy and custom designed sequences described, the example method then generates BLOBs based, at least in part, on the redundancy parameters and the custom-designed sequences. BLOBs may include byte sequences repeated at different frequencies and configurable user-designed sequences. Manipulating the redundancy parameter, manipulating the custom-designed sequences, generating the BLOBs, and providing the BLOBS may be performed by separate processes acting in parallel.
