performance 99.9 percent of the time. There are differences in total throughput capabilities between Provisioned IOPS (io1) and General Purpose SSD (gp2) volumes. Io1 volumes are designed to provide up to 320 MB/second of throughput while gp2 volumes are designed to provide up to 160 MB/second. RAID If you need more I/O capabilities than a single volume can provide, you can create an array of volumes with redundant array of independent disks (RAID) software to aggregate the performance capabilities of each volume in the array. For example, a stripe of two 4,000 IOPS volumes allows for a theoretical maximum of 8,000 IOPS. RAID 0 and RAID 10 are the two RAID levels recommended for use with Amazon EBS. RAID 0, or striping, has the advantage of providing a linear performance increase with every volume added to the array (up to the maximum capabilities of the host instance). Two 4,000 IOPS volumes provide 8,000 IOPS, three
