Have you ever wondered what the pros and cons of every raid level is? Well look no further, I stumbled upon this website which describes all forms of RAID Levels and the pros and cons of each, along with a nice description. So the next time your talking with your fellow techies, you can sound a little bit smarter :)

Check it out here, I have also included an insert below from the website for a quick read.

“RAID 50 should have been called “RAID 03″ because it was implemented as a striped (RAID level 0) array whose segments were RAID 3 arrays (during mid-90s)

Most current RAID 50 implementation is illustrated above

RAID 50 is more fault tolerant than RAID 5 but has twice the parity overhead

High data transfer rates are achieved thanks to its RAID 5 array segments

High I/O rates for small requests are achieved thanks to its RAID 0 striping

Maybe a good solution for sites who would have otherwise gone with RAID 5 but need some additional performance boost”
