1.Samsung 470 @ LSI Logic 3042E
2. Samsung 830 @ LSI Logic 3042E
On the other hand below you can see how the drive "should" work:
3. Samsung 470 @ AMD A55 SATA2 controller
And lastly, this is a RAID0 of 2x Fujitsu MAX3036RC (37GB 15000 rpm SAS drive) on the same LSI controller...
4. 2x Fujitsu MAX3036RC @ LSI Logic
I know that the controller can limit the sequentional transfer rates but has anyone got any idea why the 4K values are so bad? :/
I have also noticed that copying files and other operations are not smooth when the SSD is connected to the LSI Logic controller while there are no problems when connected to the AMD A55 one.
Of course everything happens on the same mainboard (ASRock A55 Pro3) and the LSI controller is connected to the second PCI-E (x4) slot.
Edit: Added spoilers.
