COMPARING DIFFERENT RAID LEVELS ON NAS STORAGE When it comes to Network-Attached Storage, RAID can significantly affect its performance and fault tolerance. So when you're about to set it up, choosing the right RAID level for your enterprise NAS is a pretty important decision. This article will go through different types of RAID configurations that can be used with a Network Attached Storage and compare their strengths and weaknesses. This post will cover the five most common RAID levels and their specifics, including what you should choose for your enterprise NAS. Here is a rough comparison between different RAID levels.
WHAT IS RAID 0? RAID 0 is the most straightforward RAID storage configuration that uses data striping that divides files into segments. These data chunks are kept on different drives on the array. RAID 0 is excellent for applications that require fast read and write speeds. It also is relatively safe in terms of the risk of data loss. However, RAID 0 should be avoided as a rule in applications that require a high level of security and where the loss of all data could result in catastrophic consequences. Another benefit to consider is that users can utilize all the capacity of disk drives which is good when you need to use your NAS storage to its maximum potential.
WHAT IS RAID 1? RAID 1 employs disc mirroring, which makes duplicates of the data. The original file is kept on a single disk drive, and copies of the file are retained on the remaining disk drives of the array. RAID 1 provides data redundancy by creating a fault-tolerant array. For example, in a twodisk RAID 1 configuration, if one fails, the other disk drive has the mirror data, so data isn't lost.
