Improving Flash Media Lifetime and Performance with Discards

Improving Flash Media Lifetime and Performance with Discards

Steep declines in performance can arise in eMMC and UFS if discards are not being used. But what do discards mean for the flash and the file system, and can you balance the performance and the cost to make them work with your use case?

Solid state drives (SSDs), and their embedded cousins, eMMC and UFS, are seen by many as the future of mass storage. However, steep declines in performance can arise if the NAND flash is not utilized properly – and doing that requires a steady diet of discards. What does that mean for the flash and for the file system, and how can you balance the performance and the cost? This paper will break it down for you.
