Testin RAID0 Cache settings, performance

Hi all,

I did get my hands on moded BIOS for my MB and it has newer RAID ROM in it.

What that means is that now i can change read/write cache settings on RAIDexpert for my RAID arreys.

Here are the results. I used my OS arrey for test disk and ATTO for test program.

As you see settings(shown on each ATTO screen) as Read Cache Status: Read Ahead, Write Cache Status: Write back. Gives the best performance on my system(as in specks).

Now to dum q, Can it be more harmful for my Frose 3 SSDs to use those settings? i have battery backup for power fails..

Where is this cache? ... on SSD or dos it use DDR for it?

These particular SSD's have no cache onboard and will leverage the system ram with the settings in question here.

In other words.. it's called "ram caching".

I would stick with the settings from the first ATTO screen as they more closely mimic what Intel allows with their config. Hope that helps

Thanks for quick replaying,

First ATTO screen from left or right? :)

Right one is AMD's "Default" (Read: no Cache,Write: Write Through), thats maybe why they are so slow.

first ATTO from the left with read ahead/write back.

Caching to ram generally only helps down low and has not much effect on large file performance. Which of course your OS will thank you for. Enjoy
