At Puget Systems, we’ve been using LSI RAID cards for a number of years now and have always been very happy with the quality of both the controllers and the MegaRAID software. The new 9361-8i and 9341-8i RAID controllers from LSI continue in their predecessor’s footsteps but add PCI-E 3.0 support and the new mini-SAS HD SFF8643 12GB/s connector.
Why RAID is (usually) a Terrible Idea
As president of Puget Custom Computers, I get a unique perspective on computer products and technology. Our company specializes in selling high performance custom computers, and that naturally brings up the question of RAID often. There is an overwhelming opinion out there that if you have the money and want a blazing fast and stable computer, that you should put your hard drives in RAID. We have known for years that this perception is just flat out wrong, but the problem is that the idea is so widely accepted that it is nearly impossible to convince our customers otherwise. In fact, if we try too hard to talk them out of it, we end up losing the sale! Should we be selling configurations that we know are flawed, for the sake of making the sale? We think the answer comes in the form of transparency and education! This article is just the latest effort in educating the public about RAID.

Some are for making larger, faster storage solutions. Others trade off size for increased reliability. Yet others try and accomplish both. This article gives a rundown of the basic types of RAID available today.
