Agreed.

oooo! thats a cool looking card. which one is it?

Whats with those two PCBs sticking out at 90 degrees? very scrange design of card if you ask me

[jackvdbuk]

thats a serious amount of harddrives clunk how much pr0n can you fit on them??

They will be used for storing those camera shots

And i would not worry too much about airflow to that card the heatsink is only there to make it look cool

Adaptec 3805. It is a funny looking thing. Its pretty easy to set up, but I'm obviously missing something because my RAID 5 is around the same speed as RAID 0.

I will let you know when its finished

Sorry about that, I will make the images smaller, I had a batch file for photoshop and it looks like it hasnt worked. I'll get those done today

By the way, the heatsink gets red hot, even when its idle.

Edit: I've resized all the pics to 800x600 and made them about 1/4 the filesize that they were

That space is for the battery backup unit. not really needed unless your data is of super duper importance. or you have a tendency off tuning you computer off at the wall without shutting down properly.

[Clunk]

Sorry, what I meant was, missing something in the settings that is making the RAID 0 slower than it should be, not something missing from the card itself

Have you checked the stripe size of the array? too big or too small and there will be a performance hit. for raid 0 look towards around the 8k mark

[Clunk]

Sorry, my mistake, it is the stripe size that I was changing.

Here are some bios shots, maybe I missed something? Also, the smallest stripe size is 16k and that really kills the performance.

When you enter the RAID bios, you get this.



If you click on that, you get this.



If you click on Manage Arrays, you get this (which is the RAID 0 that I was already messing with).



Back out of there to the first screen, and open Serialselect Utilities and you get this.



Open the Controller Configuration, and there are a few settings, and that is how they are currently set.



Then back one screen and into the PHY Configuration, and you get this. (I havent touched anything there).



Back to the Array Configuration Utility and it looks like this.



And then this.



And then this.



And then this. Write caching and read chaching are on (could that be it?)



It then saves and builds the array and comes up with this warning.



And then save and exit.

[Clunk]

Just had another play around with the stripe sizes and anything other than 256k gives a drop of around 3/4 of the total performance.

I also had a mess around with the read and write cache on and off, and that made it worse, and I also tried the drives cache off, and that also made it worse.

The access time is 17ms, which seems much higher than other results Ive seen. Looks like I need to have a further look

[alsenior]

playing around is the best thing you con do with something like that. i assume that you have os on a different disk.

[Clunk]

Yep, there isnt anything on the RAID at all yet.

[danroyle]

that is a beast of a system clunk

lets hope you dont spring a leak on the watercooling or we could lose half the worlds porn in one fell swoop
