Hard Disk Drives (HDD) and Solid State Drives (SSD) have been data storage media for decades.
In the 1950s, IBM released the world’s first HDD product. Since then, HDDs have grown very rapidly, from capacity to speed.
Entering the early 1990s, a new type of storage media emerged, namely SSD. At that time, SanDisk became the first company to release SSDs commercially.
Long story short, SSDs and HDDs in computers or laptops function similarly. However, there are some differences between the two as summarized below.
1. Technology
First, HDDs function by relying on rotating magnetic media, while SSDs are designed with flash technology.
2. Speed
The difference in technology also affects the speed of each of them. SSDs have better operating system boot speeds, are able to read and write data faster, and have lower latency than HDDs.
3. Durability
HDDs are also no better than SSDs in terms of durability.
Potential problems in SSDs arise from moving parts that generate vibrations, as well as high temperatures. That’s because the SSD architecture is based on rotating magnetic media.
4. Save Power
SSDs consume much less power than HDDs and this can result in longer battery life in laptops.
5. Quieter
Devices with SSDs are quieter than HDDs because, going back to their architecture, HDDs function by relying on rotating magnetic media.
