## Why It Matters
REV addressed the need for high-capacity, reliable removable storage for professional backup and archiving during the mid-2000s. It filled a gap between tape systems and rewritable optical media, offering faster random access and greater durability than tapes at a lower cost per gigabyte than hard drives at the time. While ultimately superseded by cheaper USB hard drives and cloud storage, REV represented a significant advancement in removable hard disk technology for business users, particularly in environments requiring secure, physically isolated data storage and rapid restores. Its development marked a key innovation in removable magnetic storage before the widespread adoption of flash-based alternatives.

## Notable For
- Pioneering removable hard disk technology combining magnetic and optical layers for enhanced durability.
- Offering significantly higher capacity and faster access times than contemporary tape backup systems.
- Being a direct, high-performance replacement for Iomega's Jaz drive line.
- Utilizing a unique cartridge design ensuring data integrity and protection against dust and scratches.

## Body
### Overview
REV is a proprietary removable hard disk storage system classified under the broad category of hard disks. It was developed and marketed by LenovoEMC (following their acquisition of Iomega).

### Technology and Media
- REV utilizes removable hard disk cartridges encased in protective shells.
- The disk surface integrates both magnetic and optical layers.
- This hybrid design aimed to increase durability and data integrity compared to standard magnetic hard disks.
- Standard REV disks offered initial capacities of 35GB, with later models achieving 70GB.

### History and Context
- REV was positioned as a successor to Iomega's earlier Jaz drive technology.
- It was marketed primarily as a professional solution for reliable backup and data archiving.
- The system saw adoption in environments requiring fast random access and removable storage.
- REV disks required a dedicated REV drive unit for use.
- The technology was eventually phased out as USB-connected external hard drives and cloud storage became more cost-effective and convenient alternatives.
