SanDisk Optimus Eco SSD RAID Enterprise Performance Analysis

By: Paul Alcorn | RAID/HBA in IT/Datacenter | Posted: Oct 17, 2014 2:03 pm

128k Sequential Read/Write






128k sequential speed reflects the maximum sequential throughput of the SSD, and is indicative of performance in OLAP, batch processing, streaming, content delivery applications, and backup scenarios.


The RAID arrays peak at 128 OIO during this test. The multithreaded nature of this test might be a contributing factor to the incrementally slower performance at 256 OIO. The eight-drive array stretches its legs and averages a blistering 3,736 MB/s at 128 OIO, and the eight-drive RAID 10 and four-drive RAID 0 arrays provide 1,983 MB/s at 128 OIO. The four-drive RAID 10 array weighs in with 985 MB/s. The continual similarity in eight-drive RAID 10 and four-drive RAID 0 results demonstrates that we can draw theoretical conclusions of 16-drive RAID 10 array performance from our eight-drive RAID 0 results.






The latency-to-IOPS test reveals the walking back of performance as we reach the heaviest sequential workload. Latency continues to be a very strong suit of the Optimus Eco arrays.




Sequential write performance is important in tasks such as caching, replication, HPC, content delivery applications, and database logging. The eight-drive array drops a whopping 3,566 in sequential write speed at 256 OIO, and the four-drive RAID 0 and eight-drive RAID 10 offer 1,736 MB/s. The four-drive RAID 10 brings up the rear with 985 MB/s.






The Optimus RAID 0 array continues to impress with superb low-latency performance.




The Optimus Eco's scale well in the mixed sequential testing.
