RAID 5 TESTING – AS SSD
Some of the larger demands upon the performance of the controller is when raidsets with parity are introduced. RAID 5 in particular can be a challenging load for any controller, especially with SSDs involved. High throughput and low latency requirements of SSDs can be a big challenge, lets see how a Dual Core ROC fares against its single core equivalent.
In the compressibility tests we can definitely begin to see some differences in the write speeds of both controllers, as RAID 5 always tends to write slower.
Again we will go to Crystal Disk Mark for low 4K QD1 results (4K) that are ran outside of cache leverage.
