Is an entry or Mainstream rAID Module right for your application?

rAID is pertinent to both data protection and application performance, thus it is important to select the right product for your needs.

or for connecting to a bunch of disks using JBOD mode. However, it does not offer all of the features or the performance of Intel’s

mainstream product line. the following table highlights some of the differences between the three key categories of rAID products.
