Drive:Newer variants might feature Micron's 96-Layer N28A FortisFlash Controller:In order to improve performance, Phison implemented a way that the controller utilizes it's internal 32 MiB of SRAM as some kind of "Pit-stop" that is allocated for incoming Write request in order to improve performance since it's a very quick to access and fast RAM. This implementation was called Smart Cache Flush. NAND Die:tR Average as pSLC mode: 52 µs |
