I've found a nice article (http://www.overclockersclub.com/reviews/h55_h57_motherb...) According to which:
"The SATA ports found on the board all utilize the SATA II interface. However, not all the ports are run off the same chip. The five blue ports go directly though the H55 chipset, but the two white ports are handled by the on-board GIGABYTE SATA2 chip. Unfortunately, the H55 chipset does not come with native RAID support so the five blue ports do not support RAID. However, the additional white ports can be used in RAID 0/1, and JBOD through the GIGABYTE SATA2 on-board chip."
- What's the diference between native support by H55 chipset itself and the one by on-board SATA2 chip?
hmm i don't know what you mean, in H55 i just know
the H55 chipset is a complementary pair of Arrandale as H55 itself only consists of a southbridge that will synergize with northbridge functions that have been taken over by the processor.
on-board SATA2 chip : controler Onboard SATA/IDE CTRL Mode ios part of that chipset
but i can wrong ..!
I will try to rephrase it:
- Short version: I am going to buy two sata-II HDDs and set them in RAID-0.
Should I expect any difference if the raid functionality will be handled by:
1. M/B chipset, in case I buy a mobo based on P55 chipset
2. M/B SATA-II CTRL, in case I buy a mobo based on H55 chipset
There are 4 types of chipsets for 1156 motherboards: P55, H55, H57 and Q57.
H57 - motherboards with H57 are costly (I wont buy it)
Q57 - is not available yet in my area
P55 - supports RAID 0, 1, 5 and 10, but has no support for core i3 550 integrated video. (even through I'm going to by a PCI-E Videocard, it can be handy if I get some issues with main GPU, thus I could use integrated one while waiting for replacement for example)
H55 - supports integrated GPU, but has no RAID functionality.
Now, let's take as example Gigabytes M/B GA-H55M-USB3.
It has 5 "blue" SATA-II controllers that are handled by chipset, and since it's H55, it is not possible to set up them in RAID.
But it also has 2 "white" SATA-II controllers that a re handled by SATA-II on-board CTRL. And it is possible to set these in RAID 0, 1 or JBOD.
The question is: Is it ok if I buy Gigabytes GA-H55M-USB3? Won't I have somehow limited RAID functionality? OR I should buy a M/B on P55 chipset, like GA-P55-USB3?
