AWS New I/O optimized I4i - Storage Bandwidth

Go back to list

We evaluate, the maximum number of bytes, or throughput, achievable by the instance, still with FIO but configured with the following parameters

  • 1MB blocks
  • Sequential access
  • Read then Write
  • Direct access to device without filesystems
  • libaio engine

Assertions

  • The i4i brings a large gap in term of read bandwidth: +40%
  • It's even more obvious in write mode with +110%
