Is your feature request related to a problem? Please describe.

Measure the performance overhead imposed by Rust language

Two parts:

• Sequential write using dd on SSD (expect >= 200mb/s) vs. Sequential write using Rust on SSD (measure throughput)
• Write randomly a 4kb blocks on SSD for 10K times (expect ~ 60ms) vs. Write randomly a 4k block on SSD using Rust 10K times (measure latency)
