Flash Product Lifespan Predictions You Should Know (1)

Low cost with high reliability and amazing rewrite lifespan! Reduced WAF to the limit, achieving high performance and long lifespan with SLC-level random write performance!

=durabit(TM) - The better MLC = This is a storage product with high rewrite endurance due to WAF reduction measures. The block rewrite lifespan of NAND Flash memory is 100,000 times for SLC type, 20,000 times for pseudo-SLC, and 3,000 times for MLC. However, when used in NAND storage, the lifespan values differ from those of NAND alone due to data management by the controller and firmware. To address the lifespan issues of MLC NAND-equipped storage, we consider the ratio coefficient of the amount of write data from host to storage to NAND (WAF number: ideal value is 1) and incorporate high-performance page-based FTL firmware technology, which minimizes the increasing WAF value to the extreme, achieving rewrite lifespans comparable to SLC even with MLC. WAF, known as write amplification rate, is influenced by hundreds of conditions, including the specifications of NAND flash, firmware technology, and data management structure, causing its value to fluctuate. Additionally, it is affected by the IOPS rate; for instance, if the WAF value is 10, the number of erasures within the storage becomes ten times that of the external data amount, leading to a lifespan that is reached ten times faster than predicted for NAND alone.

Flash Product Lifespan Predictions You Should Know (2)

High-performance page-based FTL technology enables long lifespan with high rewrite endurance even in storage equipped with MLC-type NAND flash!

The lifespan of storage equipped with flash memory is primarily determined by the maximum number of write/erase cycles of the installed NAND flash memory. The block erase cycles (lifespan) of NAND flash are generally 100,000 for SLC type, 20,000 for pseudo-SLC, and 3,000 for MLC. However, when used as storage, the actual lifespan in operation differs from that of the NAND alone due to data management by the controller and firmware. During data writing, the controller may erase and write to multiple blocks of NAND flash within the storage, even if the data size transferred from the host is minimal, following internal management steps. Swissbit's durabit(TM) MLC storage significantly improves durability performance by using advanced page-based FTL mapping to eliminate the effects of read disturb, along with error handling through read refresh and ECC, and read retry processing to improve uncorrectable pages depending on temperature conditions. It is a high-performance model of MLC NAND-equipped storage that combines over-provisioning features, cache DRAM, and PBM (page-based mapping).
