The Striker II's memory performance is virtually identical to the original Striker Extreme with identical timings. Both Strikers still outperform the reference boards because we could use faster memory timings – the raw performance is ~300MB/s and 3ns, about what we'd expect from 1T versus 2T.

SiSoft Sandra tells a similar story but to a smaller degree, where both Striker boards outperform the reference boards, and run almost identical to each other.
Disk Performance:
A 150GB Western Digital Raptor-X (WD1500AHFD) hard drive was used for SATA testing. We recorded the average read speeds in all cases using HD Tach 3.0.1.0's 8MB zone test.

All four boards use the same south bridge, and as expected all perform the same – the test confirms there's no design bottlenecks or BIOS errors in the SATA environment.
