Flash SSD

Flash SSD is a data storage device that uses NAND-based memory to store data persistently. Flash SSDs provide high performance, low latency storage, which provides significant performance, power consumption and cooling benefits over traditional spinning media.

Flash SSDs are used across all industries as a means to achieve significant performance increases over spinning drives.

The I/O capability of Flash SSDs is 10X faster than spinning drives. Customers use Flash SSDs for the best application response time to run virtual servers and virtual desktops and to unleash the power of analytics for real-time decision making for the business. These capabilities provide value to both IT and the business, allowing customers to differentiate their business for their customers.

How Flash SSD works

Flash SSDs work by assembling NAND-based Flash memory into an electronic non-volatile computer storage medium that can be electrically erased and reprogrammed.

These drives can be utilized in a storage area network (SAN) much the same way as traditional spinning hard drives (HDD’s) to deliver higher storage capacity and resiliency than a single storage device can provide.

What are the benefits of Flash SSD?

Flash SSDs have no moving parts, so power utilization and heat production are much lower than HDDs. Flash SSDs are more resistant to physical shock, have lower data access times, and have less latency than HDDs. Normal drive failures inherent with traditional HDDs (drive motor, platter, and seek head) do not occur.
