SMART Optimus 400GB Enterprise SSD Review - 8K Random Read/Write

The SMART Optimus heralds the beginning of a new era for the datacenter, the inclusion of MLC NAND SSDs into roles typically only served via SLC high-endurance SSDs. Providing SLC-like endurance from MLC NAND sounds like a magic trick or marketing hype at its finest.

8K random read and write speed is a metric that is not tested for consumer use, but for enterprise environments this is an important aspect of performance. With several different workloads relying heavily upon 8K performance, we include this as a standard with each evaluation. Many of our Server Emulations below will also test 8K performance with various mixed read/write workloads.

 

The 8K random read results are consistent, averaging 54,767 IOPS at QD256.

The 8K random write speed averages 25,096 IOPS at QD256. The highest speed recorded was 27,639 IOPS and the lowest was 23,175 IOPS at QD256.

50% (3,749,620 I/O's) of the 8K writes at QD256 fell into the 10-20ms range, and 28% (2,177,638 I/O's) fell into the 8-10ms range.
