Abstract
Methods, systems, and computer programs are presented for storing data in a solid state drive (SSD). One method includes an operation for detecting a plurality of streams writing to the SSD, each stream writing in sectors, a page including a plurality of sectors and a block including a plurality of pages. A write operation includes writing at least one complete page, and an erase operation includes erasing at least one complete block. The method further includes operations for allocating a write buffer for each stream in RAM memory, and for storing each received sector of a stream in the corresponding write buffer. When a write buffer stores enough sectors to fill a page, content of the write buffer is written to a page in flash memory such that the page is filled. Further, the write buffer is freed after writing the content of the write buffer to the flash memory.
