A Benchmarks read workloads with an emphasis on deep queue depth (server) reads.
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%
Which shows a very heavy bias on 64 deep queue depth performance.

The Best.
