The 128K sequential read speeds reflect the maximum sequential throughput of the SSD using a realistic file size actually encountered in an enterprise scenario.

 

The incompressible 128k sequential data speed comes in at an average of 590MB/s at QD 256, the 80% compressible data scores at 775MB/s and the 100% compressible speed comes in at 1450MB/s at QD256, but does score as high as 1700MB/s at QD 128.

 

The tests are conducted in reverse order (QD 256, 128, 64, 32, 16, 8, 4) to keep the device under load. This ensures steady state conditions are held as long as possible. Especially at lower QD the device can tend to begin to recover from steady state.

 

With SandForce devices, however, once they begin to use fully compressible data they begin to recover regardless of the QD. This is why we are observing the apparently lower performance with the higher QD in some scenarios. In actual deployment, this will not always be the case when utilizing 100% compressible data, and the results with higher QD may be in line with the mid-range QD results.

The WarpDrive provides an average of 1700MB/s in read speed at a QD of 256.

For incompressible data 72% of requests (998,105 I/Os) fell into the 40-60ms range.

 

For 80% compressible data 70% of requests (1,320,988) fell into the 20-40ms range.

 

For 100% compressible data, a remarkable 79% of requests (2,727,615) fell into the 20-40ms range.
