Multiple Raid Cards per computer?

Hello Everyone,

I'm getting ready to upgrade my system soon, and I may have assumed something incorrectly. The initial raid build is here :http://hardforum.com/showthread.php?t=1586412&highlight=

The main purpose of the upgrade is to increase the size of the raid 5 array. I bought 5 4TB HDs, and another LSI 9260 4i card. My plan is to install the Raid Card concurrently with the existing one, create a 12TB Volume, and then just copy everything over. Once the transfer is complete, I would just remove the old hardware and go along on my merry little way.

While this was probably not a the cheapest route to go, I didn't really see another way to transfer 6TB of data.

Can any of you who are much smarter than I am when it comes to data storage systems let me know if you think this will work just fine? Also, even though I have bought the hardware, any advice you have would be great as well.

Thank you!
 
No issues with having multiple RAID cards for the most part. You should be fine.
 
Something like this would have probably been cheaper and given you a lot more expandability, could have even used all 5 of your new drives.

not if his new or old drives are not expander friendly.

Also, most raid cards supports working together if you have compatable models.

But using a raid5 array on 4tb drives is very very scary thing to do, the risks of having 2 disks fail is very high.
 
Are they much higher than 2TB drives?

When I bought the 2TB drives I have now, 2TB was the biggest you could get, and I have been very lucky to have zero issues in 3 years.

It's going to be a 4 drive system, and I'll have one spare drive. Besides, 4TB drives have been out for what, 2 years now? I'd think most of the bugs are ironed out.
 
the problem is the rebuild times, which will be very long, and if another drive fails in the meantime you're stuffed.
