Shingled drives are to store PBs of read-centric bulk data as cost effectively as possible. Western Digital is developing zoned SSDs in order to speed data access and prolong the life of the drivers by making write amplification factor as low as practicable. Therefore, for this purpose, Western Digital believes that applications that use shingled disk drives could instead use zoned SSDs with few c...

Why does speed drop happen in TLC/QLC SSD?(end)

Source: local   Editor: Alex   Update Time :2019-05-27
The upgrading of flash type from SLC to MLC, TLC and QLC results in a significant decline in performance, especially in write performance, due to more charge bits to save in every cell and increasing capacity. Garbage collection and TRIM can also affect performance reduction. But now, performance reduction caused by garbage collection and TRIM is much less. In addition, the more space solid state...
