Storage Performance: Sustained, Repetitive, And Streaming Transfers
Intel’s new processor sees significant drive performance gains from the P67’s SATA 6Gb/s controller, while the older CPU does not. Since this is really a function of the chipset rather than the CPU, we believe that ASRock could probably eke a little more performance out of the P67 Transformer with a BIOS revision.
SATA write performance is hampered by drive limits and has been included only to complete the test set. What we really wanted to see is interface performance, and that was best reflected by read rates.
Repetitive transfers are affected by both bandwidth and latency. The P67 Transformer edges out the P55 Extreme4 here, while the P67 Extreme6 continues its dominance. A program error caused NEC’s off-the-chart USB 3.0 write rate: we couldn’t find the source of that error and instead decided to ignore that result.
The P67 demolishes the P55 in streaming reads, and the EJ168A USB 3.0 controller heaps further shame upon it.
