I'm not sure that is the problem. Here is a 4k write. 100% random result. 64 queue depth. Stayed consistent throughout the entire test.

Thought about this. I did a 'Low Level Format' with the Fusion-io utility it comes with.
I have written over 1.2TB to the drive in the past 2 days though. :p:
EDIT:
Another weird thing. How it is possible that it can do over twice as many 4k 100% random write IOPS than read.
lowfat! how fast does L4D loadup ?
Get it "for testing purposes only" :D
come on lowfat i didnt have it either.. i acquired it/loaded it up/posted results
what about other games ? whats your os setup on ?
did u check for any updates like firm and drivers??
ioxtreme operating @ x4 pcie ?
look in other words you should be faster then hothardwares results given your system/win7/etc

Tuning Techniques for Writes
Fusion-io is the only company that enables you to format solid state storage for optimal write performance. This section discusses performance tuning techniques, as well as considerations for writes.
Increased Steady-State Write Performance with fio-format
Under sustained, random writes, which are written randomly across the entire ioDrive, write performance will decrease. This decreased write performance is referred to as steady-state write performance.
There are very few real-world storage use cases that create this sort of write workload, the most common being RDBMS systems. However, the most common activity that triggers this behavior is running micro benchmarks rather than real-world applications.
Unlike drive form factor devices, the ioDrive can be tuned to achieve a higher steady-state write performance than what it is shipped with from the factory. The first line of tuning is to provide the ioDrive with additional working capacity, or reserve (storage capacity that is not visible but is usable by the ioDrive for internal optimization). Changing this reserve capacity can be done using the fio-format utility. Running fio-format changes the reserve size and affects the overall long term performance of the ioDrive. Repeated fio-formats are not required to get proper performance, unless the initial change in reserve size did not yield the needed steady-state write performance.
A recommended starting point is decreasing the drive's capacity by 25%. For example, if the drive is a 160 GB drive, you would fio-format it to 120GB
Warning: This will destroy all data on the drive!
Assuming the drive that you would like to format is /dev/fct0 (use fio-status to determine this), you would use the following commands:
$ fio-detach /dev/fct0
$ fio-format -s 120G /dev/fct0
$ fio-attach /dev/fct0
The following graph shows the effect of reserve on write performance under some circumstances. This graph shows that the larger the reserve, the better the steady-state performance achieved.

at page 12 is No Mercy or Dead Air levels
these are weird results lowfat, i would suggest that you keep plugging away, keep testing different configurations, make all changes that you can to find that sweet spot. you are in uncharted waters here pretty much but perseverance is the key! i see the upside down nature of the read/write benches and that really makes me feel that something is going on here....you will find it! if it writes that fast dammit it should read like a mother :banana::banana::banana::banana::banana::banana:!
Increasing PCIe increase maximum bandwidth?

PCIe bus @ 100MHz

The CPU is underclocked (2.4GHz) currently as I am trying to find my max bclk. But the sequential reads are considerably higher.
you might check to see if your motherboard allows the pcie packet sizes to be modified as well. the higher the packet setting the better. i have achieved great results with that one:up:
@ 115MHz for the PCIe bus I am now getting 876MB/s reads and 315MB/s writes http://smiliesftw.com/x/eek3.gif
However my sound card isn't working. :down:
How come the 4k scores took a dump when you clocked PCIe up?
@ low
Would you buy this card again?
