UD3R REV 2.0 + RAID 0 (SATA 3)

[KyrreS]

I'm trying to set up raid 0 with two Intel 510 120 GB SSD's on the UD3R REV 2.0 MoBo.

I've created a raid array between the two SSD's using the Marvell 9128 SATA controller (GSATA 6_7 ports).
The array shows up just fine, and I've installed Win7 64 bit on it. Everything seems to work just fine. The amount of disc-space is double (2x120GB)

But: When I run Atto benchmark there are no speed-incease. The benchmark only tells me I'm at about 450/210 MB/s Read/Write. This wud be OK if i ran 1 SSD, but I have two ...

Now, I've set up Raid on alot of SSD's and they always give me twice the speed when running Atto.

Is there something I've done wrong? Or doesn't this  MoBO support Raid between two SSD's that require SATA 3 (6 gbit/s) ??

Any tip wud be nice ....

Hmm ...

I've found a lot of posts on different forums that say the UDR3 Marvell SATA 3-controller is F.U.B.A.R.

Hi,

I could be wrong but I think using the SATA_2 ports will be better. A Moderator may confirm this or suggest another option.

The storage information suggests they will support RAID.

I can only relate to the X58A but... the Marvell chip will not give you SATA 3. You will need PCIe 6gb/s add on card. Sent mine back for refund.

You cannot use the SSDs reliably with the Marvell 9128 controller. Bad things will happen especially if you try and RAID them too. The fastest and most reliable ports on the board are the Intel ICH10R southbridge controlled oneseven though they are officially SATA2.

Thanks guys.

I think I'll buy a raid PCI-e addon card that supports SATA 3.

Why does Gigabyte put this s***ty Marvell controller on their board? They can't sell a motherboard and claim it supports SATA 3, when it dosn't. It's false advertisement ... I think I'm gonna demand my re-seller give me the PCI-e addon card for free :-)

Thanks again guys!

I know it is a dodgy area regarding the SATA3 spec on this board but to be fair to Gigabyte they were far from the only manufacturer to get duped by Marvell into putting these chips onto their motherboards. I guess that it was done because at the time there was no alternative on the market and everone wanted to be able to offer SATA3 on their boards.

   Welcome to the Forum KyrreS

  The Marvell controller on this board (88SE9128) has been posted to death.......all resulting in  #!#"¤"!"!!!"%¤¤%  Performance ......there is only one fix that you already worked out.........."Raid Card"

  You can pay a little.......up to taking out a second mortgage.

   The cheapest option I currently know of that will work at speed on this board.....is the HighPoint Rocket Raid 640 PCI-E card......these will come in at about 100 to £120.......and yes there bootable out of the box.....6Gb/s compliant and will support JBOD,0,1,5,10 and carry two Raid controller chips

  The only problem with these cards is it will add about 25-30secs to your boot time......some people rate this point to be a very important factor....some not (like me) ..........explanation!

  if someone came up to me while fine tuning my F1 McLaren out on the front lawn and said.........."My car start faster then yours" .......

                                                 I'd ask him to turn around to see where his second head was

Aussie Allan:

Any difference between the HighPoint RocketRAID 620 and the HighPoint RocketRAID 640 you mention? I only need two ports ...

regards,
Kyrre

The 620 has 1 controller the 640 has 2 controllers because it has 4 ports. Aussie Allan may correct me on this but you could connect on SSD to one controller and the other to the remaining controller to get a better performance.

  teknology9 is correct

  Best performance is with two physical drives over the four ported Card as it does have 2 controllers and will future proof you if you want to add more drives later.....as an example.....I have 4 Spin points (HD502s) and get a tidy 525 and 540Mb/s read and write on Raid0.......not bad for plattered drives

  The performance of the 620 card I can't comment on with experience.....I own a 640 but what I have stated was gleaned for several scorces re performance of the 640 over the 620.......you get what you pay for

  these cards are a generation or two down now which gives it it's better price point.......get the latest card and you'll be paying 3 times + for maybe 5% increase in performance........not worth it in my books just for bragging rights

[teknology9]

teknology9 is correct

Credit where credit is due, Aussie Allan informed me about this a good while back because I asked the same question and this how I knew.......there's honesty for you!!!!!  

The Samsung Spinpoints are quite reasonably price also but if you have SSD's try them.

Nice, thanks again guys!

I called my MoBo re-seller and said the Marvell SATA 3 is crap. He gave me a HighPoint RocketRAID 640 for about 78 euro (600 NOK), so I'm happy with that.

Finally I can get good use of the speed of my new SSD's .... 

[Dark Mantis]

We will expect pictures of the performance tests don't forget! 

[KyrreS]

Oh, sure!  

I will cook up some nice benchmarks. Give me some days ...
