Systems and techniques relating to storage technologies are described. A described technique includes operating drives such as a solid state drive (SSD) and a disk drive, where the SSD and the disk drive are virtualized as a single logical drive having a logical address space, where the logical drive maps logical block addresses to the SSD and to the disk drive. The technique includes determining, based on a file to be written to the logical drive, a target logical address that corresponds to one of the SSD and the disk drive, and writing the file to the logical drive at the target logical address to effect storage on one of the SSD and the disk drive.
