SLC SSD FAQs

Industrial M.2 SSD

 

For users in need of flash storage for an industrial application, an SLC SSD is a common choice. SSD stands for solid state drive, which is an alternative to HDDs, or hard disk drives. SSDs are considered to be more reliable than HDDs, and combining SLC NAND flash memory with SSDs offers even greater reliability. Some forms of SLC SSDs, such as SLC SATA III, meet military grade standards for reliability and are dependable for industrial functions in which protecting data is essential.

 

Why choose SSDs over HDDs?

SSDs have edged out HDDs for a number of reasons, but reliability is chief among them. HDDs rely on mechanical components to read and write information on a disk. These moving parts are subject to breakdowns, which can compromise the integrity of the data. They also make the process of reading and writing data more time consuming.

 

SSDs don’t have moving parts. Instead, data is read and written according to the functions prescribed by an internal processor. The processor directs the operations in the flash memory of an SSD, so that it is not necessary to have any moving parts. Although the specific speed of an SSD depends on the processor, it will be faster than the processing speed of an HDD. Advanced SLC SSDs, such as SATA III, are dramatically faster than HDDs as well as lower performing SSDs that have slower processors.

 

What is an SLC SSD?

SLC SSDs use single-level cell NAND flash technology. In an SLC SSD, a single bit of data is written to every cell. Reading and writing data only involves retrieving or saving one bit of data at a time, which allows for fast processing. SLC SSDs also offer increased data protection, thanks to longer lifespans and the reduced risk of data being lost when a power failure occurs during the write cycle.

 

SLC SSDs are designed with integrated features to maximize the potential of the storage system. For instance, wear leveling technology helps to ensure that no part of the flash memory is overused, which would cause it to wear out too quickly. As with most industrial products, SLC SSDs are used in applications that require tolerance to shock, vibration, and temperature.

 

When should developers choose an SLC SSD?

Developers and OEMs who are seeking reliable, rugged flash memory should use SLC SSDs when they can’t afford to risk data loss. Embedded flash storage often operates in very challenging conditions, and SLC SSDs are up to the task. SATA III SSDs also come with additional features, such as the ability to quickly erase sensitive date when necessary.
