Characteristics & Advantages
- Very high Read data transfer rate
- Very high Write data transfer rate
- Disk failure has an insignificant impact on throughput
- Low ratio of ECC (Parity) disks to data disks means high efficiency
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
- Image Editing
- Video Editing
- Prepress Applications
- Any application requiring high throughput
