Q How is the AS SSD read score calculated?

Read Score = SeqR*0.1 + 4kR + 4k-64tR

• SeqR = Sequential read speed
• 4kR = Random 4k read speed
• 4k64R = Random 4k read speed (64 queue depth)

All speeds are measured in MBps

Looking at the SSD Group Test average scores:

• SeqR=488
• 4kR=25
• 4k64R=276

So the total score is weighted in the below proportions:

• SeqR=14%
• 4kR=7%
• 4k64R=79%

This shows a very heavy bias on 64 deep queue depth performance.
