| RLL |
Run Length Limited |
An old system what was used with
the 8088, 8086, and 80286 Processors. These drives were
temperature sensitive making the drives disk to change the physical
diameter and then write over previously written data on adjacent
cylinders. |
| IDE |
Integrated Drive Electronics |
This type of drive has its drive
controlling electronics integrated into the drive and did not require an
external drive controller board for operation. |
| EIDE |
Enhanced Drive Electronics |
Allowed the computer to have more
than two drives |
| SASI |
Shugart Associates System
Interface |
Predecessor to SCSI |
| SCSI |
Small Computer System Interface |
Bus Oriented that handles
concurrent operations |
| SAS |
Serial Attached SCSI |
Improved SCSI, uses Serial
communication instead of a Parallel Interface |
| ST-506 |
Seagate Technology |
Historically a Seagate Interface |
| ST-412 |
Seagate Technology |
Historically Seagate Interface
with a minor improvement over the ST-506 |
| ESDI |
Enhanced Small Disk Interface |
Backwards compatible with the
ST-412 and ST-506 drives but they are faster and more integrated |
| ATA |
Advanced Technology Attachment |
The Successor to the ST-412,
ST-506, and ESDI by the integration of the disk controller into the
drive itself, this is incapable of concurrent operations. |
| SATA |
Serial ATA |
Modification of the ATA drives,
These use Serial Communications instead of Parallel and no longer
require need the large ribbon cable. |
| eSATA |
External Serial ATA |
External SATA Drive that uses a
eSATA port, not a USB or Fire Wire port. There are USB docking
ports available for the standard SATA drives that are very good for
external backups of your data or for extra storage capability for users
of Video Editing Software, where the user has a lot of videos to store
and not enough of internal data storage space. |
