Designing a NAS

Hi I'm designing a new nas with 8 1TB drives and I have a $200 for a hardware raid card. I am stuck between Raid 50 and Raid 6 / Which raid card to go with. Any help would be appreciated. The motherboard I'm using is an Intel DP45SG   and I have the two pci-e slots filled with dual gigabit adapters and one pci slot with a gpu (Total ethernet bandwidth of 5Gb's because of NIC teaming. I have both of the x16 slots open and I'm pretty sure they also can take an x8 or x4 raid. Any help finding a raid card / configuration would be appreciated.

You can't get a good hardware RAID card for $200 with RAID 50 or RAID 6 support. Those kinds of cards go for $300+.

 

You can pick up a used 9211 or M1015 for $150 on eBay, they have RAID 10 support which is a good redundant setup. You would only get 4TB out of your drives, though.

You can get nice raid cards from ebay, that will do anything you want for $100-150 easy. 

 

This card would more than fit your needs, and is only $100.

Raid 6 will give you the most storage space with coverage for 2 disk failures.  With your 8x1tb setup, this would give you 6tb of storage.

Raid 50 would be 2x raid 5s striped together.  So you end up with the same amount of potential drive failures, but if 2 drives fail in the same raid 5, you lose it all. 

 

Honestly, I would go with the raid 6.  It will be the simplest and gets you what you want.

 

Also, do you already have the drives? Or are you buying new drives?

Hey gadgetguy,
 
@wpirobotbuilder and @ChineseChef gave you some good options. Are you looking for more redundancy or speed? How much of those 8TB would you like to actually have as usable? Do you have any specific needs that you want this array to meet? Is there a reason why you want to do a 8x1TB instead of 4x2TB or 2x4TB (speed, redundancy, future upgrades)?
 
I would say go with either simple RAID5 or RAID6. Both give you significant speed boost and offer one/two drive failure tolerance and both of them use less storage space for redundancy compared to RAID10, RAID50 or RAID60.
 
What drives are you using? I would recommend going with RAID/NAS class drives for smoother and safer performance. I would suggest checking out WD Red drives and their good features for RAID environments. Here's a link: http://www.wdc.com/en/products/products.aspx?id=810.

I stand corrected.

 

I would make sure your motherboard is on the compatibility list for that card, which you can find here. You should be able to use almost any drive with the card, and you'll also want to check operating system compatibility (shouldn't be a problem).
