Our is a 10K drive - this is my dmesg output (from 2.6.12-rc5) - only
difference I can see is the ANSI SCSI revision (I have never
investigated the SCSI subsystem much in the kernel so how does one
interpreted the ANSI SCSI revision number ?).

Fusion MPT misc device (ioctl) driver 3.01.20


I have tried switching the 335 for another one but the performance is
till very low so I am quite sure that it is not a hardware problem.
Also compiling the driver as a module does not make any difference.
