Abstract: Methods are disclosed for partitioning a solid state storage device to create multiple virtual storage devices, which may include one or more virtual tiers of data. Some examples of the methods address self-tiering of the data between the multiple virtual tiers within the physical device. And some examples provide for automatic movement of aging data blocks (i.e. data blocks for which and identified write threshold has been exceeded) to larger over-provisioning pools of blocks to reduce the rate of aging for those blocks.
