WebJan 30, 2014 · DRAM handily outperforms NAND flash in terms of performance, especially when comparing write operations. This is because NAND flash doesn't overwrite existing data at the byte level. It has to write data in full block increments, which requires that an entire block be erased before a new block of data can be written. WebDec 10, 2024 · host_write_commands will not represent that value because it's the number of commands, not the number of bytes, and the number of bytes is variable per command. …

Webof NAND writes/host writes. Host writes is the data sent from the operating system (OS) to the SSD while NAND writes are what is actually written from the controller to NAND. Normally, NAND writes > host writes, due to metadata and rearranging of available space on NAND. A minimal WAF—as close to 1.0
