SOFTRAID OVERHEAD CPU SOFTWARE

You can see what the differences in cost and performance are on the desktop space.ДЄs for ГЇssues in setting up RAIDs, to be honest, I see more issues with discrete hardware soltions than I do with on board software solutions on the whole. Take a look around the net and search for hardware versus software based comparison testing. But, as note above, some folks want every bit of performance and choose a discrete solution for no CPU overhead and slightly better performance. This is just my opinion, but if all the user needs is a simple RAID 0 or RAID 1 stripe, its a waste of money on a discrete hardware solution. There's a bit more CPU overhead there, but not enough in most cases to warrant a hardware based system. Most onboard chipset based software soltuions can hande those with little issue. Most folks on desktop are looking for basic RAID 0, RAID 1, or RAID 0+1 across 2-4 didsks. Although there are numerous enterprise level hardware solultions for desktop, you tend to find most of these options in the server space.ДЇor desktop use a hardware based solution is typically overkill. This usually means you are looking for many disks (more than 2 for sure), RAID 1, RAID 5, perhaps reliable JBOD and doing all that with a minimal amount of resource drag on the system. As HiVizMan noted, if you require an enterprise level of reliability and resource allocation, then it is best served to go with a discrete hardware based platform.

The decision between a discrete hardware based solution versus a software based solution boils down to how robust of a RAID platform you are wanting to set up. I've been using RAID set ups for quite a few years. We buy stuff that we know will not make one iota of real world difference to your system but we still buy it. The difference between current motherboards on-board RAID options with SSD's in RAID and using a dedicated RAID solution card is slight and therefore far more attractive to users.ДЄs to the individual users personal motivation to do anything, logic plays a very small part I suspect. As the core aspect of a RAID, namely redundancy is not present.

So we tend to like RAID 0 which while called a RAID is technically not one. We gamers and enthusiasts are all speed freaks at some level. So to answer directly it boils down to capacity and type of raid. So if you needed to have 12 different drives in an array you would go card. However with SSD and SATA6G the speed issue is largely a thing of the past but the volume or capacity issue is still a factor. You have to understand that a high speed RAID was really only possible using a dedicated card. The distance between performance and cost has narrowed quite a bit.
