You seem concerned about loss of data quite a bit, yet you're copying it all to a RAID 0? In RAID 0 one disk dies and you have absolutely nothing .
A massive RAID 0 and off you go.

Currently I have a raid0 SAS array in my system (I know, you must think I really hate my data to have this) and really like the performance over a single disk. A couple months back I built a new system for myself at work which is using SSDs and can't ...

You effectively lose to RAID5 or RAID10 (Which is a mirrored raid 0 array) which get's the best of both worlds.
You need at least 3 disks.
Hit when writing, over a RAID 0 striped array.

I'm currently running a Raid 0 configuration and wondering if I could switch it to a Raid 1 config without losing any data currently on the 2 drives. Is there any software that will allow it to happen? Do I have to create a complete image of the raid ...

Situation is this. A PC with 2 hard disks, in an RAID 0 Array.
The electronics on one of the disks has failed. I can not find the same board for the disk (I've tried this, removed board from the OK disk, and the second, the damaged one, works fine).

It will not try to "fix" your RAID.
You could try RAID Reconstructor .
You literally have striping the disks, there is no redundancy .
RAID 0 caused half of data to be on one disk and half on other.
You cannot.

I'm looking at a server which has RAID1+0 array and a RAID 5 array. The RAID 1+0 is used for system files and the RAID 5 array is used for SQL server database and log files.
The RAID 5 array is made up of 6 72GB SAS drives. In the HP array configuration...

I'm planning to use ZFS on my system (HP ML370 G5, Smart Array P400, 8 SAS disk). I want ZFS to manage all disks individually, so it can utilize better scheduling (i.e. I want to use software RAID feature in ZFS).
The problem is, I can't find a way to...

I have a single partition on a Raid 0 array of 3 drives using my motherboard's raid support(DFI INFINITY 975X LGA 775 Intel 975X ATX).

My question is: when is it appropriate to simply create one large array with fast read & write performance, such as RAID 10, instead of creating smaller arrays for specific applications?

RAID 10 comes in 2 flavours:
RAID 1+0 where you build 2 RAID 1 arrays, then stripe them.
Disc array correctly, get it wrong and you're in for a long rebuild time.

After upgrading to Ubuntu 9.04, my raid 5 array is no longer being assembled correctly. Right now, from boot, it will start a raid array using ata-MAXTOR_STM3500630AS_9QG03T0L-part1, at /dev/md0, but that is fail because it isn't my whole Raid 5 setup...

You are updating the initramfs after you change /etc/mdadm/mdadm.conf right? If you don't, when you boot your changes won't be used .
Also see what /usr/share/mdadm/mkconf outputs and try using that.
Using the UUID is the preferred method.
