US 2026/0037178 A1 · DATA STORAGE METHOD AND STORAGE DEVICE

Abstract

The invention provides a data storage method and a storage device. The method includes: obtaining first data and second data; caching the first data in a first buffer in a plurality of buffers, wherein the first buffer is connected to a first physical group; caching the second data in a second buffer in the plurality of buffers, wherein the second buffer is connected to a second physical group; and storing the first data cached in the first buffer and the second data cached in the second buffer into the first physical group sequentially. Therefore, balance may be achieved between reducing costs, maintaining basic data write operations, and reducing write amplification.
