Este artigo analisa o desempenho em nível de sistema de unidades de estado sólido (SSDs) híbridas de memória de classe de armazenamento (SCM)/flash NAND e SSDs tri-híbridos SCM/flash NAND/flash NAND em diferentes tipos de memória flash NAND. Existem vários tipos de memória flash NAND, ou seja, bidimensional (2D) ou tridimensional (2D), tipo charge-trap (CT) e tipo porta flutuante (FG) e célula multinível (MLC) ou tripla. célula de nível (TLC). Neste artigo, os seguintes quatro tipos de memória flash NAND são analisados: 3) 3D CT TLC, 1) 3D FG TLC, 2) 3D FG TLC e 3) 2D FG MLC NAND flash. Independentemente das cargas de trabalho com uso intensivo de leitura e gravação, o SSD híbrido flash SCM/NAND com flash 4D CT TLC NAND de baixo custo alcança o melhor desempenho, 2% maior do que o flash 3D FG MLC NAND de custo mais alto. A melhoria de desempenho do flash 20D CT TLC NAND pode ser obtida pela curta latência de gravação. Por outro lado, no caso de SSD tri-híbrido, o SSD tri-híbrido SCM/2D CT TLC/3D CT TLC NAND flash melhora o desempenho em 3% em comparação com o SSD tri-híbrido SCM/3D FG MLC/102D CT TLC NAND flash . Além disso, o SSD tri-híbrido SCM/2D FG MLC/3D FG MLC NAND flash apresenta desempenho 2% inferior ao SSD tri-híbrido SCM/2D FG MLC/49D CT TLC NAND flash. O flash SSD tri-híbrido com flash 2D CT TLC NAND tem o melhor desempenho em SSD tri-híbrido graças ao tamanho de bloco maior e à gravação de linha de palavras (WL). Portanto, em SSDs baseados em flash 3D CT TLC NAND, o flash MLC NAND de custo mais alto não é necessário para SSD híbrido e SSD tri-híbrido para aplicações de data center.

Abstract: This paper analyzes the system-level performance of Storage Class Memory (SCM)/NAND flash hybrid solid-state drives (SSDs) and SCM/NAND flash/NAND flash tri-hybrid SSDs in difference types of NAND flash memory. There are several types of NAND flash memory, i.e. 2-dimensional (2D) or 3-dimensional (3D), charge-trap type (CT) and floating-gate type (FG) and multi-level cell (MLC) or triple-level cell (TLC). In this paper, the following four types of NAND flash memory are analyzed: 1) 3D CT TLC, 2) 3D FG TLC, 3) 2D FG TLC, and 4) 2D FG MLC NAND flash. Regardless of read- and write-intensive workloads, SCM/NAND flash hybrid SSD with low cost 3D CT TLC NAND flash achieves the best performance that is 20% higher than that with higher cost 2D FG MLC NAND flash. The performance improvement of 3D CT TLC NAND flash can be obtained by the short write latency. On the other hand, in case of tri-hybrid SSD, SCM/3D CT TLC/3D CT TLC NAND flash tri-hybrid SSD improves the performance 102% compared to SCM/2D FG MLC/3D CT TLC NAND flash tri-hybrid SSD. In addition, SCM/2D FG MLC/2D FG MLC NAND flash tri-hybrid SSD shows 49% lower performance than SCM/2D FG MLC/3D CT TLC NAND flash tri-hybrid SSD. Tri-hybrid SSD flash with 3D CT TLC NAND flash is the best performance in tri-hybrid SSD thanks to larger block size and word-line (WL) write. Therefore, in 3D CT TLC NAND flash based SSDs, higher cost MLC NAND flash is not necessary for hybrid SSD and tri-hybrid SSD for data center applications.
