OK, Here goes.
I have been running 6 Crucial C300/64Gb SSDs in a raid0 strip on my C4F for some time now, and have been achieving 1025/1040 Mb/s read, and 404/420 Mb/s write, benching with Crystal Disk Mark.
So, I recently bought 6 Crucial M4/64Gb SSDs and installed them on my C4F. Improved those marks to 1059 Mb/s read / 505 Mb/s write.
This is what I have noticed.
The M4s are now on my C5F in the same configuration. Using the same Crystal Disk Mark, I am only achieving 650Mb/s read and 395Mb/s write.
The C300s are on my SaberTooth in the same configuration. Using the same Crystal Disk Mark, I am only getting 650Mb/s read and 395Mb/s write.
It seems to me that the SATA chips is running in SATAII mode on both of the new boards.
The C4F has a setting that can be manualy set in the BIOS,(6G/s or 3G/s) this option is not offered in either of the new boards.
Has anyone else noticed this?
Not sure, may be related to the fact that I don't have an FX 8130P/8150P CPU on the boards.(may have to wait and see)
