RAID, redundant array of independent disks, uses redundancy to provide a more robust disk drive array capable of operation even with the loss of a drive. RAID 1 replicates data with a 50% overhead. RAID 5 and 6 are more common in larger arrays with less overhead as more drives are added to the mix but with a tradeoff in performance.  

Mark Anthony, Product Line Manager at Microchip Technology, talks about the company's SmartRAID 4300 Series, which is designed to accelerate the operation of RAID arrays implemented build on NVMe drives.
