Abstract: Described is a system comprising: a storage device; a bus; and a host apparatus including a host memory and a driver module, wherein the host apparatus is coupled to the storage device via the bus, wherein the driver module is operable to: retrieve a logical to physical address mapping from the host memory; and provide the logical to physical address mapping to the storage device via the bus along with a read or write operation request. Described is a method comprising: retrieving a logical to physical address mapping from a host memory; and providing the logical to physical address mapping to a storage device via a bus along with a read or write operation request. Described is a machine readable storage medium having instructions stored thereon that, when executed, cause a machine to perform the method described above.

Abstract: Examples are disclosed for identifying read/write access collisions for a storage medium. In some examples, a plurality of write access requests for access to a storage medium may be received at a controller for a storage medium. The plurality of write access requests may be associated with separate logical block address (LBA) ranges. The separate write LBA ranges may be stored to sets of first registers. A read access request to the storage medium may also be received and a read LBA range associated with the read access request may be stored to a set of second registers. The separate stored write LBA ranges may then be compared to the read LBA range to identify overlapping ranges that may indicate read/write access collisions to the storage medium. Other examples are described and claimed.
