Well, I found the first answer on the SATA0 port but not the answer to my main question. on the slow SATA0 port issues, it turns out that the ASUS P6T motherboard's SATA connectors 0 and 1 are JMicro ports with known limitatons and its best to not use them (P6T Deluxe MOB doesn't use the JMicrons BTW), so I've relegated the JMicron SATA ports to drive my DVD writers. On a P6TSE, the SSD needs to be connected to any of the 6 SATA ports on the Southbirdge that is also happens to be running a pair of 1TB HDDs in RAID0 using the ICH10 RAID driver.
My main question remains unanswered as to how to adjust anything (if possble) to bost the X25-M upto to its max rated read speed.
- If you want the best performance of your hardware (SSD, graphics card and processor), did you try at Control Panel set Power Options for High Performance (normally i set Processor minimum performance at 50% and leave max. perf. at 100%). The default is Balanced.
- Also i think you should try others benchmarks (in my experience HD Tach always shows better performance than HD Tune), like Crystal DiskMark and AS SSD Benchmark. Be careful in doing many write benchmarks, regarding SSD's lifespan.
- In HD Tune my G1 and G2 SSD's give something as 230 MB/s, but in Crystal Mark, the same devices perform at aprox. 260 MB/s (sequential read speed).
