Here is a comparison of write speeds using different levels of compression rates.
For sequential xfres there are three main bands
• 0% to 8% Compression = ~100% of max speed
• 25% to 46% = Compression = ~45% of max speed
• 67% to 100% Compression = ~30% of max speed
4K QD1
Performance approximately the same regardless of compression ratio
4K QD 4 & QD 16
Compressible 4K xfers are assisted with queue depth.
EDIT: I added an X25-M just to help show where compression might be helping.
