Storage Performance: Transfer Diagrams

ASRock P67 Transformer: P67 Gets LGA 1156 Compatibility
By

We were surprised to see the P55 Extreme4’s SATA controller perform slightly better than the P67 Transformer’s in our read transfer diagram, especially after seeing the P67 Extreme6 perform so well. The Extreme4’s NEC USB 3.0 controller falls behind the newer EtronTech part used on both P67 boards, but neither solution is capable of exceeding the 2.5 Gb/s limit of the P55’s PCIe pathways.

Write performance is the C300 SSD’s weakness, yet we still see the P67 Extreme6 pushing over 220 MB/s. The P55 isn’t far behind however, and the mixed board again takes third place.
