Title: Do all boards require using RAID to get 6gb/S?
Post by: Yankee6 on May 25, 2011, 08:40:35 pm

I was looking into buying a GIGABYTE GA-880GA-UD3H, but saw someone in a review said you must use raid in order to get 6Gb/sec.  I dont plan on using RAID and wanted to know if this was true of this board and of ALL boards?  If this is the case then I dont need to bother buying a board with anything faster than 3 Gb/s.  Thanks.

Hi
There are quite a few motherboards around now that will support SATA3 6GBs out of the box. I am fairly sure that this is one of them. It was only the first boards that used the Marvell 9128 controller that were supposed to support that spec but didn't.

Yes this board does support 6Gb/S, but like I said someone said it ONLY works with RAID.  Thats why I want to know if this is true then I could just go for less expensive board without that capability instead.

 I don't get all this hype about the new Sata 6GB/s. ... The conversion from gigabit to megabytes is roughly 3 Gb/s = 375 MB/s.

 So 6Gb/s = 700 MB/s......I know of none, non-raided Sata drive, that would come close to this figure


   This was a snip i just pulled off a page on the net.......the shall we say standard Sata II platter drive, spinning at 7200 rpm will net you about 65 to 90 Mb/s depending on outer edge or inner edge.........from what I'm seeing ATM ... 6gb/s mechanical drives max out at about 150mb/s tops!.....so to get to the 700Mb/s saturation point......about 5 to 6 drives (raided).........SSD a little different but still short.

 My thought for what I THINK you want is have a moderate sized SSD for your operating system and put all your programs on a cheaper,  conventional HDD.....even with a quickish SSD you'll be pressed to saturate the SataII except in a burst....for real world, you wont notice the difference

there is a small difference .

Sequential Access -  Read 355MB/sec (SATA 6Gb/s)
                                      265MB/sec (SATA 3Gb/s)
Sequential Access - Write 75MB/sec (SATA 6Gb/s)
                                     75MB/sec (SATA 3Gb/s)

As you see the read is about 1/3  faster while the write is about the same. I use raid 0 on 2 500 gig  7200rpm drives and it is close but not as good as a ssd but for the price raid 0 suits me fine.
