ServeRAID M5000 Series Performance Accelerator Key for IBM System x 8
RAID 5 random workload performance
In Figure 6, read performance in RAID 5 configurations demonstrates similar IOP performance as RAID 0.
When comparing RAID 5 write performance,
MegaRAID FastPath software demonstrates 2.5 times the IOP's performance over an identical
configuration with this feature disabled.

RAID 0 application performance
MegaRAID FastPath software significantly boosts server application performance levels for typical
workloads as well. MegaRAID controllers with MegaRAID FastPath software disabled are limited to
80,000 IOPs, whereas application performance improves by up to 45% with MegaRAID FastPath software
enabled (Figure 7).
