Actually i dont have any issue with read and write,If you have experience with Cassandra NoSQL database,Its very read and write intensive.It will approximately doing 10 Million concurrent read and writes.AS per Cassandra documentation "Cassandra can write 50GB of data in 0.12 milliseconds, more than 2,500 times faster than MySQL."
50GB in 0.12 ms is 500TB in 1.2 second. SATA III buses at 6GB/sec need a "parallelness" of (nearly) 100 channels to soak up that data. How many drives must be written-to in parallel to sustain that write rate is ... Beyond my math skills.
