How big were hard drives in 1990?

Changes in Storage Space Over Time Ten years later, in 1990, a “normal” hard drive (like the ones produced by Maxtor) held about 40MB, with more expensive options able to store more than 100MB. Fast forward to present day, and you can buy a 3.5-inch hard disk drive with 15TB of storage space.

What is the capacity of hard drives?

The primary characteristics of an HDD are its capacity and performance. Capacity is specified in unit prefixes corresponding to powers of 1000: a 1-terabyte (TB) drive has a capacity of 1,000 gigabytes (GB; where 1 gigabyte = 1 billion bytes).

What is the maximum capacity of a hard drive?

Hard drives are workhorses when it comes to capacity. The storage size of hard drives is exponentially larger than solid state drives, and current capacities for consumer hard drives — currently reaching up to 12 TB — are anticipated to continue growing.

How can a ST-412 MFM hard drive be integrated?

How can a ST-412 MFM hard drive be integrated with a modern PC? I have a Seagate ST-225 20MB hard drive. It used a ST-412 MFM (Modified Frequency Modulation) controller which unfortunately went to the great bit bucket some time ago.

What kind of encoding does a MFM drive use?

While the electrical connections are known and well-documented the format of the data on the drive is also not what was used on later IDE drives. MFM drives use RLL encoding. That’s when it gets fun because there were different configurations of RLL encoding. Controllers needed to look at the disk and figure out which was used.

When was the Modified Frequency Modulation ( MFM ) drive made?

A case in point is the circa 1984 Modified Frequency Modulation (MFM) drive which [Michał Słomkowski] was tasked with recovering some files from.

How big is the largest hard drive in the world?

In the 2000s and 2010s, NAND began supplanting HDDs in applications requiring portability or high performance. NAND performance is improving faster than HDDs, and applications for HDDs are eroding. In 2018, the largest hard drive had a capacity of 15 TB, while the largest capacity SSD had a capacity of 100 TB.
