Which advantage of SSDs contributes to their portability?

The advantage that contributes to the portability of SSDs is that they are lighter and occupy less physical space. Solid State Drives, unlike traditional Hard Disk Drives (HDDs), do not have moving parts, which not only makes them less prone to mechanical failure but also allows them to be designed in much slimmer and more compact forms. This lightweight nature and smaller physical footprint make SSDs ideal for portable devices such as laptops, tablets, and external drives, enhancing their overall portability.

Higher storage capacity, faster operation, and cost-efficiency are all important aspects of SSDs, but they do not directly relate to the aspect of portability. While high storage capacity is beneficial as it allows for more data storage, it does not impact how easy it is to carry the device. Similarly, faster data access improves performance but does not have a direct effect on the physical portability of the drive. Cost is a factor that influences purchasing decisions but does not affect how portable an SSD is. Therefore, the lightweight and compact design is the key characteristic that makes SSDs especially portable.
