Jaz Drive

Jaz drive is the successor of Zip drive. Jaz drive is a SCSI device, which is an external drive. Iomega introduced Jaz drives in 1995. Jaz drives have rigid platters. Jaz drives can backup data up to 2GB. It is similar to Removable Rigid Disk (RRD) drive. Jaz drive has self-terminating interface (SCSI-2). It houses the conventional hard disks. Jaz drives connect internally to the computer through SCSI or IDE and externally through parallel ports. An availability of an adapter called as Jaz Traveler helps in connecting the Jaz drive to the parallel port.

Jaz drives are portable and help in backing up files for the user. Jaz drive is recognized as a hard disk and hence any application can be run through the same. Storage capacity available are 1GB and 2GB. 1GB Jaz drive does not support 2GB Jaz disk but 2GB Jaz drive supports both 1GB and 2GB cartridge. Jaz drive requires SCSI controller because it uses SCSI interface. Jaz drives have automatic playback and backing up options. It has speed almost like any other hard drive (but not equal to or greater than). External Jaz drive requires 100-240V and 50-60Hz frequency. In the year 2002, Jaz drive was discontinued. REV drive is the successor of Jaz drive.

Jaz drive Models

Some of the models of Jaz drives are as follows:

Iomega JAZ 2GB Ultra SCSI External Drive (PC/Mac) 31191
Iomega 2GB SCSI External JAZ Drive Disk Storage System V2000s 30271700
Iomega JAZ 2GB Internal Disk Drive VS2000si Jazz 50 Pin
Iomega JAZ Drive – V1000s etc

Advantages

Removable media
Good performance
Helps in upgrading hard disks
Meets SCSI-2 specifications
System can be run from Jaz disk
Good transfer rate of 5.5Mbps
Good seek time of 12ms
Backward compatible
Lets conversion to and from the wave file format
Storage capacity is larger than Zip drive
Anti-gyro mechanism (Iomega) to prevent vibrations

Disadvantages

Jaz drive have certain limitations, due to which it has been discontinued, some are mentioned as follows:

Expensive in terms of buying and installation
Very unreliable (dependability is less)
Storage capacity is less
Less secure
Disk requirement is more for backing up large data
Backing up process is time consuming
Even the disks are expensive
Jaz disks are very costly compared to DAT tapes
Supports for short term storage
Prone to ‘click of death’
Prone to overheating (initial Jaz drives)
Read-write damage results in corruption of data
Dust particles enters trough the side case of the drive, which corrupts the surface of the disk

SCSI Data Recovery
Jaz drive uses SCSI interface and data loss may happen from Jaz drives. Loss of data from SCSI Jaz drive can be due to hot swapping, damaged boot record, In such situation Remo recovery application is the greatest asset available. Read on, to know more about the application.
