I just tried the drive in AHCI and my performance score dropped from 7.4 to 6.9 .
EVGA tells me the AHCI implementation on my motherboard (790i Ultra) is not too swift, so I'm not surprised. I did load the latest JMICRON driver from their website as well..
I'm gonna stick with my 7.4 and be happy for now, unless you have any ideas for me.
I've run an X25-E on a ICH9 mobo and the worst (degraded) score I ever got was 7.8. I'm not sure what you are doing.
Are JMicron drivers on your mobo for the eSATA ports? The SATA ports are 3.0Gb/s and would need Nvidia drivers. I have no experience with SSD’s & Nvidia but somehow your drive is being gimped.
I would seriously consider getting a ICH10 board if I had spent that much money on an SSD to end up with that score.
I have an Alienware M17x | T9600 @ 3.41 GHz OCed| and the score I get is 7.7 with AHCI on clean install of win 7 x64
I switched to either AHCI legacy or native and I still get the same results. The other options I have on BIOS are either RAID or ATA.
The Crystal diskmark gives 4K random reads only 20.30 MB/s and I don't know if something is wrong with my system or the SSD. I upgraded to the latest firmware 8850
The chipset is NVIDIA nForce 730i according to CPU-Z
The chipset is probably the bottleneck since I cannot exceed the 7.7 WEI no matter what drivers I use or offset (1024 default win7 or manual set to 64)
