Abstract
Several embodiments include a host computer coupled to a solid state drive (SSD). The filesystem of the host computer can receive a write pointer from the firmware of the SSD. The write pointer can reference a next available page to an erase block in the SSD. In response to a file write request to store a target file, the filesystem can determine a logical address range to store at least a portion of the target file based on the file write request and the write pointer. The filesystem can then generate a sector write command to send to the SSD. The sector write command can specify the determined logical address range.
