RAID 5 or RAID 6

[JayKnowHow]

I was wondering if I should go with a RAID 5 or 6 array. If I was to go with the RAID 5 I would get more storage for my money but it would be less reliable and I would need to keep a second Drive on hand incase one of the drives fail. On the other hand the a 6 array it would be almost fail proof but I would loose one more drive just for backup.

 

If you about a cheep 6 port RAID card please let me know.

 

If you Have anything else to add please do so accordingly.

 

Thank You

Is this for home use or for a business?

If you're just using it for home use, go with raid 5. 

There is no need for raid 6. 

 

If you want a foolproof solution, buy another external HDD and run a incremental backup. 

 

Also, this is a inexpensive 8 port raid controller.: http://www.ncix.com/detail/highpoint-rocketraid-2720sgl-8-port-20-75407.htm

It has really good reviews.

Read this thread, i posted comments relevant to this thread there.

 

Tl;DR

 

RAID 5 if < 12TB

RAID 6 if >= 12 TB

If you value your data more than the cost of an extra drive, then RAID 6 is the way to go.
