AMD: SB750 Southbridge On The 790FX Chipset
The SB750 has been AMD’s flagship southbridge since last year, when it was released together with the 700-series chipset family. This lineup consists of the discrete graphics chipsets 740, 770, 790X, and 790FX as well as the integrated parts 740G, 780G, 785G, and 790GX with its Side Port graphics memory option.
All discrete graphics chipsets are manufactured using a 65 nm process, while all of the integrated solutions with DirectX 10 (and DX10.1) compatible IGPs are etched at 55 nm. Low-end chipset configurations are typically paired with the older SB600 or SB700/SB710 southbridge components, but we’d recommend to go for the SB750 when possible. The SB750 offers six SATA/300 ports with AHCI support and AMD’s RAIDXpert technology, which supports RAID 0, 1, 1+0, and 5, as well as JBOD. The RAIDXpert tool has to be used through a browser-based interface, which allows for administration and monitoring of your RAID array. It cannot extend arrays across additional controllers.
The SB800 will most likely be introduced together with the next-generation platform based on the AMD 800-series chipsets.
Gigabyte MA790FXT-UD5F
We used an enthusiast motherboard by Gigabyte, the MA790FXT-UD5P. The board utilizes AMD's 790FX/SB750 chipset combination and accepts all Socket AM3 processors and DDR3 memory.
Although the chipset supports six SATA/300 ports, Gigabyte decided to add more storage options through a JMicron JM322 controller. This provides four additional SATA/300 ports (see white connectors) that are totally independent from the chipset’s SATA ports. The JMicron ports only support RAID 0 and 1, but they can also be used for Gigabyte’s Smart Backup feature.
This motherboard’s I/O panel is full of connectors, including eight USB 2.0 ports, two Gigabit Ethernet ports, audio jacks, PS/2 keyboard and mouse, and audio. But it does not offer eSATA connectivity. However, Gigabyte includes an eSATA slot adapter, providing two eSATA ports should you need them.
First! But anyway, it's nice to know that the Intel southbridge still stands up as a competitor to the LSI card, meaning I don't need to drop a ton of money on a raid controller for a desktop raid setup.. I just ordered 2 1TB Samsung Spinpoint F1's and plan to Raid 0 them. It's not exactly 'high performance' but it's high enough performing for the needs of the normal desktop user.

Why there are not many reviews about the nvidia chipset mobos for AMD ???
It would be nice if TOM gives full reviews of those boards too...Many people show the desire to go SLI with AMD but are unwilling because of the problems and issues that are floating around the net about them...So it would help them much...
Interesting article, though I may not setup a RAID 5 on such a board (due to financial constraints), at least I have a reference when choosing a board to do a RAID 1 or 0.
at last, i've always wanted to see this comparison! well done intel!
what do the transfer diagrams look like? can these raid controllers flatten out the transfer diagrams of conventional drives i.e. make max and min read about the same?
What I do not understand is why bother with the degraded writing performance.
When you build a RAID array, you expect that array run normally most of the time, don't you ?
My RAID 5 server, in last 3 years, only 1 time has one disk failed, and only took 1 day to rebuild the array and run normal again.
1 day out of 3 years (> 1000 days) means less than 1 per mil of its life time it has to run in degraded write. And the quality of HD is much improved since 3 years ago (when I bought my HD to build my array)
Let's be conservative, let's say when you build a RAID 5, you expect it failed twice a year (very bad expectation), to rebuild it still take less than two days, mean less than 1% of time per year.
I will choose solution that has more performance that run more than 99% of time (i.e. ICH10 on RAID5) over one that has more performance that run less than 1% of its time (i.e MegaRAID on RAID 5) any day. ^__^
So if degrade write performance only contribute less than 1%, why bother ?
how about a software raid in the mix ? like the linux implementation, just to compare is the chipsets have any benefit compared to a fully software colution ? you did throw in a HW card so a SW solution should complete the picture ...
1000 microseconds = 1 milisecond
The access time is between 110 mircoseconds and 360 microseconds, so between 0.11 ms and 0.36 ms
Since Schmid and Roos refuse to post any retail prices for anything, the LSI’s MegaRAID SAS9260-8i is $600.

Corrected on page 10. Thanks Adrian.
Good article but really strange choice of hardware. Surely the people who want these results are people looking to use SSD's in servers as well as the very small enthusiast community?
In which case why havent Nvidia based server boards for Opterons or Intel based servers been submitted?
Also raid 0 is great for a theory but realistically raid 10 is the most used raid solution, especially with solid state drives. It would have been good to have an update with this configuration.
Hope you do a follow up article.
All of a sudden "Intel seems to have optimized its ICH10R for RAID 1+0"
On page "Benchmark Results: I/O Performance"
Nowhere else do I see any mention of 1+0 benchmarks nor any graphs.
Does Nvidia and AMD solutions mean you have to have a working OS installed first? The descripcion of the raid setup tools is a bit unclear.
To me the conclusion should be don't spend $600 on a new bottleneck for your raid performance. Who cares about degraded performance? No one in their right mind keeps a system running on degraded performance as you use your raid to secure important data you are not willing to risk it being destroyed by a second drive failure.
Also too little focus is spent on the processor difference. Todays multicore cpus lend them self very well to these integrated solutions and processor overhead is almost a non-issue. Lastly, is it possible intel has some advantage as the SSDs are intel? $600 for LSI's card with the not included battery backup option as the only selling point, is better invested in a UPS for the entire system.
there is a big oops in the charts on the i/o section
amd sb750 raid5 is exactly the same as intels ich 10r raid0 in every chart
um, you put one too many zeros on one of the access time charts. amd sb750 is listed as 600, i think it should be 60...
Should probably note that raid 5 is not supported on all 6 of the intel chipset ports (only the first 4).
I'm still living with that error.
I'm curious if the INTEL SSD are a case for the Intel chipset to have an advantage? I don't know, but they should have used another brand like Corsair or WD for this test. The LSI card I guess very expensive and out of reach for most home sever builds as are the Intel SSD's. It was a good article though seems like a lot of work! Good job TH!
I moved from JMicron Raid on a Gigabyte board to an Intel ICH7R Asus board for the same reason Tom’s pointed out. My Raid 0 setup with two 7200.10 drives tops out around 120mb/sec read while the Intel let me have 140mb/sec. I have since replaced the 7200.10 with 7200.11 1.5TB and have 200mb/sec read speed from the Intel chipset. Equivalent offer from AMD and Nvidia 3 years ago couldn’t push more than 120mb/sec like the JMicron.
"Please get that Gate.com pop-up ad window OUT OF MY FACE!!!!" I agree lonewarder. I have been reading toms for years now and frankly the ads are getting really annoying. I know they have to pay their bills too but how about keeping them less obtrusive.
Good article tho. I was curious as to how ich10 stacked up against the offerings from amd and nvidia.
