All the performance specifications of NeoSapphire all-flash arrays (ranging from 300K IOPS to 600K IOPS) are strictly verified through 100-hour tests, so they are sustained numbers rather than peak values.
Conventional disk arrays are usually deployed with multiple spinning disks designed to store data on rotating platters and accessed via mechanical read/write heads.
Unlike conventional disk arrays, flash arrays are built with multiple SSDs. With the benefits of SSDs, flash arrays can provide better performance compared to conventional disk arrays.
