Definition - What does Flash Storage mean?
Flash storage is the term used to describe any electronic device which is capable of performing as a storage repository with the help of flash memory. It can be anything from a fully integrated all-flash storage array to a simple universal serial bus device. Flash storage is capable of improving the efficiency and performance for many applications compared to traditional storage media.
Techopedia explains Flash Storage
Flash storage makes use of flash memory, which stores data in an array of memory cells. The cells can range from traditional single cell to multi-level cells. It differs from conventional storage methods in not having a write-protection mechanism with respect to data, but has faster read and write capabilities.
Compared to hard drives, flash storage provides many advantages. They have better performance capabilities as the speed to access data is less in the case of flash storage. In other words, it removes rotational delay and seek time. Their fast processing capabilities for applications and quick access to stored data make it more business friendly than traditional storage options. As they can handle large workloads better and more quickly, they are good while working on complex data sets and operations. Another key advantage of flash storage is that it offers more durability. Unlike hard disks or other storage techniques which make use of moving parts, flash storage does not have any, and as such users need not worry about damage to storage units due to mishandling of the moving parts. This also helps in better and more efficient performance of the flash storage. Additionally, compared to hard drives or similar options, flash storage does not require much power, which can result in reduced energy costs.
However, there are certain disadvantages associated with flash storage. Flash storage is expensivecompared to other options, such as hard drives. Flash storage also tends to suffer performance issues at higher capacities. They also have capacity issues, thus limiting their sizes compared to hard disk drives.
