An object storage data store may be implemented using storage devices providing multiple extents, where individual ones of the extents include multiple independently addressable, contiguous blocks and where updating an extent is performed by updating the respective independently addressable, contiguous blocks sequentially using a series of write operations. The storage devices may include shingled magnetic recording devices and may include conventional persistent storage devices. The key value data store may implement a superblock structure, index structure, and data store structure using respective portions of the multiple extents, where updates to each of the structures is performed sequentially using a series of write operations. The key value data store may further implement a cache for the index structure to minimize input-output (IO) density of the object storage data store.
