Raid 0

Post by **Nellyboy** » Thu May 21, 2009 12:56 am

Hi fellas, been messing about with me comp and went for a raid setup using the onboard controller.

2 x 500gb samsung hdd's used in raid0 partitioned as 350 and 640. Loaded os onto 350gb part.

Vista64

I used crystaldiskmark to compare speed of this with the old hdd I was using. Old hdd was so bad it was a joke.

Sammy's seem great and well quick booting and getting into bf2.

My results:

Well I've been messing about with setting up a Raid 0 using 2 spare Seagate 250gb sata drives

Here is a screenshot of both drives tested individually before raiding them

After setting up Raid 0 with a 100gb and 400gb partition I tested again

Now I was hoping for a better result than that

Before setting up the raid my main OS drive was a Samsung 750gb sata drive and this is the test result on that

Now that is only slightly slower on the Seq test but much quicker on the 512k and similar for the 4k.

So have I not set it up right or is the Samsung drive just so much better on its own than the 2 seagates put together?

Not sure Eagle, we need a real geek like Trig or Myo in here to explain the findings. Looking at the result of my WD black hdd it seems very quick for a single drive. MegaZone's looks nippy too.

Heres my Raid0 pair of 36Gb 16Mb cache raptors that I use as my C drive:

Eagle, what are the models of the drives?

Also what motherboard do you have as it can also be down to the raid controller and the block size it set the raid array to.

Mine is on the ICH10R with a 64k block size raid 0, my limitation is the age/type of drives

im going to get some 320gb F1 drives soon which will give it a good boost

The drives are Seagate Barracuda ST3250820AS 250gb sata.

Mobo is Gigabyte GA-P35C-DS3R rev 1.1

Block size is 128k

Initially I had the drives plugged into the onboard GSata port (purple) but I have now started again and plugged them into the ICH9R ports (orange)

Tested again and now have a better result

I think I'll leave it like that for now and see what sort of performance it gives me over my single drive

That's loads better Eagle. Hmm, now we just need to make it faster.

Post by **madman045** » Sat May 23, 2009 12:44 am

128k is huge.....

Either 64k or 32k if you like to defrag often

Wow, Runcore Pro IV ssd on jkk's ThinkPad. Its a rocket with the ssd.

I would hope so Nelly for Â£360 for 128GB

Id love SSD, just couldnt take out a 2nd mortgage to buy them and a decent raid card
