High-Speed NAND can read data at speeds up to 200 megabytes per second (MB/s) and can write data at speeds up to 100 MB/s. These speeds are achieved by leveraging the new ONFI 2.0 interface specification and a four-plane architecture with higher clock speeds. In comparison, conventional SLC NAND is limited to 40 MB/s for reading data and less than 20 MB/s for writing data. To maximize the performance benefits of High-Speed NAND, users must use the new ONFI 2.0 synchronous interface standard.
