Solid-state storage devices may be employed to store data maintained by a database management system, but may have characteristics that reduce the efficiency of interactions between the database management system and the device. A storage subsystem may receive information indicative of internal boundaries within database data. A segment of the database data may be selected for compression, wherein the size of the segment is based at least on one or more the internal boundaries, the memory page size of the solid-state drive, and a predicted rate of compression. The compressed segment may be stored if it has a size less than the memory page size of the device. If it does not, compression may be retried with a smaller segment of data or a portion of the data may be stored in uncompressed form. Additional segments of the data may be stored on the solid-state drive in a similar manner.
