Flash Storage

What Does Flash Storage Mean?

Flash storage describes any type of long-term storage repository supported by flash memory. Flash storage may also be referred to as solid state storage.


Unlike traditional hard disk drive storage, flash storage has no mechanical parts which makes it a good choice for storage in mobile technology. Flash storage comes in a variety of formats and prices, ranging from inexpensive consumer-grade USB drives to enterprise-level all flash arrays.

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.

Compared to hard drives, flash storage drives provides many advantages, including faster read and write times. Flash memory's quick access to stored data and fast processing capabilities makes it more business-friendly than traditional storage options.

Because Flash can handle large workloads more efficiently than traditional mechanical storage, it's a good choice for working with complex data sets and multi-step, distributed operations in the cloud. When compared to hard drive use, flash storage does not require as much power and does not generate as much heat, which can result in reduced energy costs.

Although flash storage for enterprise use has come down in price in recent years, it is still more more expensive than traditional hard drive storage. Another limitation to consider is that flash memory has a limited number of write/erase cycles (PE cycles) before wearing out, so depending on its use, a flash drive's lifespan may not be as long as a mechanical hard drive.
