1. A method for use in a distributed storage network (DSN) including a plurality of distributed storage (DS) units configured to store encoded data slices, the method comprising: storing, in a standard-width vault including a first plurality of DS units, a first set of data slices corresponding to a first representation of a data object, the first set of data slices including at least a first write-threshold number of data slices encoded using a first set of dispersal parameters, wherein the first set of dispersal parameters specifies a first write-width and a first read-width associated with the standard-width vault; storing, in a low-width vault including a second plurality of DS units, a second set of data slices corresponding to a second representation of the data object, the second set of data slices including at least a second write-threshold number of data slices encoded using a second set of dispersal parameters, wherein: the second set of dispersal parameters specifies a second write-width and a second read-width associated with the low-width vault; and at least one of the second write-width or the second read-width associated with the low-width vault is less than a corresponding first write-width or first read-width associated with the standard-width vault.
