What is SMR Hard Disk

SMR stands for "Shingled Magnetic Recording." It's a technology used in hard disk drives (HDDs) to increase storage density. In SMR drives, data tracks overlap like shingles on a roof, allowing for higher capacity. However, it can lead to slower write speeds compared to traditional HDDs.

What is the structure of this technology?

In Shingled Magnetic Recording (SMR) technology, data tracks are arranged in overlapping layers, similar to shingles on a roof. This overlapping structure allows for higher data density, enabling larger storage capacities in hard disk drives (HDDs). When data is written to an SMR drive, adjacent tracks must be rewritten as well, which can result in slower write speeds compared to traditional HDDs.

In which year did this technology come?

Shingled Magnetic Recording (SMR) technology was introduced in the mid-2010s, with the first SMR drives becoming available around 2013-2014.
