Your JetStor system engineer will also make recommendations, which you can use to make the most informed decision about your RAID needs.

RAID LEVEL 3: RAID Level 3 Storage | RAID 3 Advantages and Disadvantages

The data block is subdivided ("striped") and written on the data disks. Stripe parity is generated on Writes, recorded on the parity disk and checked on Reads.

RAID Level 3 storage requires a minimum of 3 drives to implement

RAID LEVEL 3: RAID Level 3 Storage | RAID 3 Advantages and Disadvantages

Characteristics & Advantages

Very high Read data transfer rate

Disadvantages

Transaction rate equal to that of a single disk drive at best (if spindles are synchronized)
Controller design is fairly complex
Very difficult and resource intensive to do as a "software" RAID

Recommended Applications

Video Production and live streaming
