Description

Support structure for hybrid SSD

Technical Field

Background

In the last half century, with the continuous progress of computer architecture and chip processing technology, the gap between the CPU performance and the input/output (IO) performance of a computer system has been expanding. The bottleneck of computer system IO performance is Hard Disk Drive (HDD). Although the capacity of the HDD has been greatly increased over the years, the access speed has been increased only to a limited extent due to the existence of the mechanical rotation structure. For example, over the past 20 years, the CPU frequency has increased by about 600 times, while the hard disk speed has increased by only 20 times. Compared with a magnetic disk, a Flash Memory (Flash Memory) is a high-speed, low-power consumption, shock-resistant, small, light and portable chip-level storage medium, and is considered as a key component for improving the IO performance of a computer system. In the last 10 years, under the combined efforts of the industry and academia, the flash memory technology has advanced greatly, and great industrial revolution that Solid State Drive (SSD) based on NAND flash memory replaces HDD is taking place in the storage field.

An SSD based on a NAND Flash memory is generally composed of a host interface Layer, a Buffer Management Layer (BML), a Flash Translation Layer (FTL), and a NAND Flash Array Layer (FAL). The system comprises a host interface layer, a BML (bus management platform) and an FTL (file transfer layer), wherein the host interface layer is responsible for communicating with a host, the BML is responsible for managing a data buffer area of the SSD and is a key component for improving the performance and prolonging the service life of the SSD, the FTL is responsible for simulating the SSD into a traditional hard disk only with read-write operation so as to adapt to the current file system, the FTL is generally composed of three modules of address mapping, garbage recovery and wear leveling, the address mapping is a core, and the FAL is responsible for actual physical data storage and is composed of a plurality of NAND flash memory chips. BML and FTL bias software design is the key firmware in SSD design. When the hybrid SSD based on the cross-layer design is installed, an SSD bracketing structure needs to be used, so that the hybrid SSD can be installed and fixed in the case.
