Internal Hard Disk size 3,5" Seagate ST-1102A with data capacity from 89 MegaByte PATA IDE AT

The ST-1102A is a hard disk drive manufactured by Seagate Technology. It was an internal storage unit for desktop computers and is a relic from the prehistoric era of computing, as it came equipped with a capacity of only 89MB.

Here are some of the specifications of the ST-1102A:

• Manufacturer: Seagate Technology
• Capacity: 89MB
• Interface: IDE (Integrated Drive Electronics)
• Form Factor: 3.5-inch
• Rotational Speed: 3500 RPM
• Cache: 8KB (very small by today's standards)

The IDE interface is obsolete and not compatible with modern computers that use SATA or PCI Express interfaces. Additionally, the 89MB storage capacity is minuscule by today's standards. A typical modern smartphone has a storage capacity many times greater.

The ST-1102A was released in 1989, making it over 30 years old. It was a high-end drive at the time of its release, but it is now considered to be a very outdated and obsolete piece of technology.

The disk turns on regularly and is seen by the PC interface, however it was not possible to test its functionality due to the lack of compatibility between the AT system of the disk and the PC.
