Abstract
A method for host-side data classification according to embodiments, includes: writing a data sector directly from a host to a storage device; storing the data sector in the storage device; sending a write completion acknowledgement from the storage device to the host; in the background: classifying the data sector on the host to estimate an expected lifetime of the data sector; assigning a data type index to the data sector based on the expected lifetime of the data sector; and asynchronously sending the data type index for the data sector from the host to the storage device.
