For any IT professional, RAID (Redundant Array of Independent Drives) is likely a familiar concept. Originally, RAID was developed to replace high performance, but expensive mainframe disk drives with an array of lower cost PC hard disk drives (HDDs). Today, as enterprise storage transitions to Solid State Drives (SSDs) that offer higher reliability and lower failure rates, RAID remains a key strategy to protect critical data.

SSD RAID is now as common as RAID with hard disks has been for decades — and for the same reasons. SSD RAID makes the system as a whole more reliable through the use of redundant disks and error correction. In systems ranging from single servers to large storage arrays, and even special-purpose PCs used for gaming or graphics, different RAID levels are used to get the most out of SSDs. SSD RAID can use as few as two drives, or dozens.

This white paper explains the most commonly used SSD RAID levels and their unique advantages and disadvantages. For more information on Samsung enterprise SSDs, visit our solution page.
