I am wondering what the needed peak write throughput is, and also the amount of data being collected per day.
Using multiple volumes might help, as seeks would be independent. If you are writing to shares (as opposed to LUNs) then using SSDs for metadata tiering and possibly data caching might also help. Either approach would require using bigger physical disks to keep the same capacity.
You might also look at the CPU load in the performance graphics. RAID-10 would likely reduce the CPU load, since no parity computations would need to be done. It would also reduce the amount of disk I/O needed for writes.
