As SSDs have gotten faster, especially with the advent of NVMe technology, the vast majority of users don’t need to worry about RAID 0. However, there are still some niche applications where combining the speed of multiple, very fast SSDs is helpful – so in this article we are going to look at the current state of NVMe RAID solutions on a variety of modern platforms from Intel and AMD.
Qualification: LSI 9341-8i & 9361-8i RAID Controllers
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.
Product Qualification: Intel RS25DB080 RAID Controller
In this article we will be reviewing the Intel RS25DB080 8-port RAID controller which features two 800MHz processor cores with 1GB cache memory. Our testing however shows that this card suffers in terms of performance when compared to the Intel RS25DB040 and RS25DB080.
Product Roundup: Intel/LSI RAID cards
As hard drives are becoming faster and faster, you need a RAID card that is able to keep up with them. Today we will be reviewing the performance of five RAID cards. From LSI: the 9211-4i, the 9750-4i, and the 9240-4i. From Intel: the RS2BL040 and the RS2BL080.
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.
The acronym ‘RAID’ stands for Redundant Array of Independent (or Inexpensive) Disks. There are several variations designed to meet different needs. 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.
