Sandook delivers pooled SSD performance-boosting management
Blocks&Files, Monday, April 13th, 2026
MIT and Tufts University researchers have devized a performance-boosting management scheme for pooled SSDs that overcomes block-erase-and-write and garbage collection performance dips.
The scheme is called Sandook and separates short- and long-term performance blocking features of SSDs by having a 2-layer control structure fed with data from agent software running in storage servers.
SSD performance can vary from faster to slower depending on the ratio of read and write requests. As writing requires a block-level erase and write process, it is much slower than reads and a preponderance of writes to an SSD can slow its read performance.
