Hello Natezor, I am sorry for the behavior you are experiencing with the Intel® SSD.
It is certainly odd to obtain different results since the operating systems should be completely transparent for the drive itself. I suggest testing the Intel® SSD in a different SATA controller (or port) or a different system altogether, if possible. Updating the BIOS in your system may also help.
Latest firmware for Intel® SSD 320 was released August 2011.
