ASUS / ASRock / MSI / GIGABYTE BIOS's with updated RAID OROM - Page 195

post #1941 of 3916
Hello, here is a picture of the option in question:

1464816

As you can see, one may choose between iRST and RSTe, I installed Windows with iRST. Does this matter in regard to TRIM support?

If you choose "IRST", you will get TRIM in RAID0 support automaticly.
Unfortunately the picture is somehow upside down.

OK thx a lot for clarification,

yes the picture is upside down, I was kind of in a hurry while posting and didn't check before uploading.

So TRIM is working automatically...

... here are my results of AS SSD Mark

1465292

These results are optained using 4 Corsair Neutron GTX in Raid 0.

Those are connected to 4 SATA II ports (because I have no controller providing 4 SATA 6 Gbit/s Ports).

My question is:

Are those normal results?

If I am not completly mistaken, the theoretical maximum throughput of a SATA II Port is 2.4 Gbit/s (300 MB/s).

Those values times 4 (since there are 4 drives in RAID 0) result in 1200MB/s, however as you can see only about 800 MB/s are obtained - is that normal?

Youd get better results with using just 2x on the SATAIII interface wink.gif

Yeah.... he'll get 900+ read for sure but poorer writes with just 2 drives.

The only way to top it is a Z87 or a nice expensive pci-e 8x RAID card smile.gif

EDIT: ps Those writes are thumb.gif

These are normal results; my 4x Force GT 120GB on sata-2 raid0 scores 1716.
If you disable c-states in bios, you get a much better 4K write score.

Thanks,

one more question, if I could organize a 4 Port Sata 6Gbit/s Controller (via Slot-Card or by chaning the Motherboard to a ASRock Extreme 11 - since I know of no other Board providing 4 or more such ports, that can act in union), by how much would those speeds increase? (just a rough estimation)

That's what I feared.

No raid ssd max speed is around 550 MB on sata3 port from the 768 that the port will allow.
No raid ssd max speed is around 300 MB on sata2 port, you limit your ssd because of the max port of 300 MB.

Ssd normal speed is around 500-550 MB
Sata 3 port or 6GB port is max 768MB smile.gif so i dont know if in raid 0 they will join and be 1536 MB because the ports dont let u go higher than 768, but maybe im wrong.
Sata 2 port or 3GB port is max 300MB i dont know how u get 800mb, u should get max 600mb not even, i think in sata 2 port max ive seen is 540-550 mb smile.gif

It is adviced for max performance to use on sata3 6GB the Ssd or the raid of ssd and on sata2 3gb use for hdds or raid of hdds, hdd even if is sata 6gb will not go more than 200mb smile.gif and all to be the intel ports.

Also check this, a good ideea is use RAM for cache RamDisk:

They already run @ 500MB/s and you could have two of them using that speed whereas if you raid them you can only achieve 768MB/s because that is as fast as a Sata3 6Gb/s can handle. Put your different OS's one on each. It will be just as fast but be 2 separate drives. I don't think the rest of the hardware can realistically handle anything faster so you won't see very much gain in Raid0. If you are using HDD's in the loop they will be your bottleneck when you transfer files from drive to drive. That is why you cache them with RAM. If you transfer files from SSD to SSD with no cache then you will notice a much greater gain being able to read from one and write to the other @ 500MB/s. It will greatly improve your drive to drive speeds.

Can you be more specific about Z87 or give me a link, its a new mainboard?

LE: im reading already about it biggrin.gif

C-states you mean the CPU C1E / CPU C3 Report / CPU C6 Report? or other CPU options? im intrested because i use mac os and i have at boot time some options with C-States, i want to understand exactly. thx!
