Best All-Flash Storage Arrays

Flash memory is often confused with solid-state disk (SSD) storage. However, they are not the same thing. A solid-state drive is any storage device without moving parts. Thus, flash is a type of SSD, but not every SSD is flash. Because people are familiar with flash USB drives, many users confuse the terms. An all-flash array (AFA) replaces the disk supporting input/output processes and storage.

SSDs use flash memory to ensure a high-speed when reading/writing data, reaching speeds of over 5GBs/s. To achieve this, they read or write multiple flash memory chips simultaneously, having between 4 and 16 channels to access flash storage.

Both technologies are based on solid-state chips, and thus considered solid-state storage. However, they are used differently in a computer system.

Flash memory is used for storing, reading, and writing data at high speeds.

RAM (random access memory) is the part of your computer memory that performs operations on the data retrieved from storage.

Both flash memory and RAM are faster than hard disk drives (HDD) because of their solid-state nature. RAM, however, is faster than flash. On the downside, it is also more expensive. It is also volatile, which means it cannot hold data when the power is down.

Regarding costs, there are two types of RAM used in computer systems: SRAM (static RAM) and DRAM (dynamic RAM). Static RAM is usually faster, but as such, much more expensive than DRAM. Therefore, organizations use SRAM for memory cache, and DRAM for operational memory for the operating system and applications.

Flash memory is less expensive than RAM and is non-volatile. Therefore, it can hold data without being connected to power. The downside of flash memory is that compared to RAM memory types, it is significantly slower. Organizations use flash in use cases that require reduced power consumption and persistent storage at a lower cost.

All-Flash Storage Arrays are high-performance storage systems that use SSDs instead of traditional HDDs.
