IOMeter – Average Transaction Time
With 43 nm flash enabling lower latencies, the G2 is able to push the envelope even further here. I’m working on a means of reworking these graphs to make for easier interpretation, but for now I’ll take a sampling of raw data and put it out there for the masses:
| Drive
|
Transaction Time (ms)
|
| Intel X25-M G2
|
0.27
|
| OCZ Vertex (1.30)
|
0.39
|
| OCZ Summit 250GB (beta)
|
1.10
|
| OCZ Apex 250GB
|
1.15
|
| Intel X25-M 80GB (8820)
|
0.32
|
| WD VelociRaptor 300GB
|
6.19
|
| WD RE4-GP 2TB
|
11.68
|
The above figures were taken at a queue depth of 1, meaning controllers could not take advantage of their parallelism. The X25-M G2 model takes the cake on absolute fastest transaction service time. Vertex is close, but when you consider the tiny scale here, it is still 44% slower.
