## Why It Matters
The Jaz disk played a notable role in the mid-1990s as a high-capacity, portable storage solution, bridging the gap between lower-capacity floppy disks and later technologies like USB drives. Its magnetic cartridge design emphasized durability and reusability, catering to professionals and businesses needing reliable data backup and transfer. While eventually overtaken by more convenient formats, the Jaz disk represented an important step in the evolution of portable storage, addressing the growing demand for larger data capacities in a compact, removable form factor.

## Notable For
- **High Capacity**: Offered 1GB and 2GB storage, surpassing floppy disks and early CD-Rs.
- **Cartridge Design**: Durable, removable hard disk format for secure data handling.
- **Dedicated Hardware**: Required a Jaz drive, ensuring compatibility and performance.
- **Professional Use**: Popular among businesses and creatives for backups and large file transfers.

## Body
### Technology
The Jaz disk utilized magnetism to store data, similar to traditional hard drives, but in a portable cartridge form. Its 1GB and 2GB capacities were achieved through rigid disk platters housed in a protective casing.

### History
- **Release**: Launched in 1995 by LenovoEMC (formerly Iomega), building on the success of earlier removable media like the Bernoulli drive.
- **Market Positioning**: Targeted users needing higher storage capacities than floppy disks (typically 3.5" disks held 1.44MB) but lacking affordable, portable alternatives.

### Specifications
- **Storage**: 1GB or 2GB per cartridge.
- **Interface**: Connected via a Jaz drive, often integrated into computers or used as an external device.
- **Durability**: Marketed as a robust, reusable medium for frequent data transfers.

### Legacy
The Jaz disk’s popularity waned with the rise of cheaper, higher-capacity USB drives and optical media (e.g., DVD-R). However, it remains a notable example of mid-1990s storage innovation, reflecting the era’s balance between capacity, portability, and cost.
