SSD RAID - please share successful configurations

I have finally decided to install openSUSE KDE 11.2 on my desktop computer (after using it on my laptop for a few months). I’m going to pull out my existing HDD (with Ubuntu) and install a new HDD for openSUSE. I thought this would be a great opportunity to upgrade to a faster solid state drive system (with RAID).

Please share your successful SSD RAID configurations on openSUSE. I’m personally looking for a low cost, reliable SSD RAID solution, but I’ll look at any configurations that are proven. Even if it costs more, I want to make sure I use a setup that others have used with success on openSUSE.

Thanks.

P.S. Here’s my machine info in case anyone is interested:

If you have the choise in your bios to make a raid from 2 or more ssd drives connected to motherbords sata connectors
you can configer them as raid 0 1 0+1 5

Installing opensuse 11.2 will recognize the raid and install

I myself have two 64GB ssd’s in raid 0 with Nvidia mediashield raid support in bios
used stiping for the 2 , make them bootable
Mobo is Asus P5N-D
and the speed is like lightning

Thank you. What model SSDs are you using? What model SSD would you recommend?

I have 2 PATRIOT MEMORY 2.1 each 64 gb
they are 2 years old now
never had any problems with them
only you have to use specials parameters in your fstab
and elevator=noop as boot parameter
/dev/disk/by-id/raid-nvidia_aeecbbcb-part6 swap swap defaults 0 0
/dev/mapper/nvidia_aeecbbcb_part7 / ext4 noatime,defaults,data=writeback,acl,user_xattr 1 1
/dev/disk/by-id/raid-nvidia_aeecbbcb-part5 /boot ext4 acl,user_xattr 1 2

part 7 is configured as /

Thank you! Very helpful.

Where did you find those parameters? I’d like to understand what you are doing so I can troubleshoot if I run into any problems.

Those parameters you find with a search on this forum and with google

key words SSD EXT3 or EXT4

But be aware that the fstab parameters very between the ext3 and ext4

What i showed you is on ext4

Thank you! That’s great help! I’m looking forward to the type of fast performance you are enjoying :slight_smile:
