SFSA030GQ1BJ2TO-C-LB-226-STD Datasheet/PDFSolid State Drives (SSDs)
SFSA030GQ1BJ2TO-C-LB-226-STD is one of solid-state drives (SSD), also known as flash storage systems now used in many computing applications, especially laptops and digital cameras. An SSD works by using integrated circuits or flash memory to store data rather than spinning hard disk drives.
SSD technology uses memory chips, rather than mechanical spinning disks, for storage purposes. This is why SSDs are noted for being much faster than their hard drive counterparts and provide improved performance in any application it is used in. In addition, SSDs also produce zero noise, lower power consumption and better heat dissipation compared to hard drives.
Data stored on an SSD is written to blocks of flash memory cells. The NAND flash memory technology used in most SSDs nowadays can be divided into two types: Single-Level Cell and Multilevel Cell. Single-Level Cell (SLC) provides the highest performance and durability but is also more expensive. Multi-Level Cell (MLC) is more inexpensive but has lower performance and durability. SFSA030GQ1BJ2TO-C-LB-226-STD utilizes MLC technology.
SFSA030GQ1BJ2TO-C-LB-226-STD is a 2.5-inch SATA III interface SSD with a capacity of 120GB. It can reach up to 550 MB/s sequential read speed and up to 490 MB/s sequential write speed. With the help of a host of advanced technologies, SFSA030GQ1BJ2TO-C-LB-226-STD can extend its product’s life with data retention and reliability for lower OOb rating.
Application Field
SFSA030GQ1BJ2TO-C-LB-226-STD is more frequently used for laptop PCs and low-energy consumption digital devices. The lower power consumption and better heat dissipation of the SSD can bring out its best performance and extend the life of the device. It is also used in small-sized server and NAS storage, embedded Motherboard etc.
Working Principle
An SSD is composed of a controller, NAND flash memory semiconductors and a power source. The controller serves as the brain of the device, which is responsible for controlling the operations of the device such as data reading and writing, power saving and error protection.
The power source supplies power to the controller. The flash memory stores data on a chip and is composed of a number of cells. The data stored on the chip is written to the cells respectively. The flash memory has the advantages of being shockproof and able to store data even without power.
Whenever data is written to or read from the cells, the controller controls the data operations and manages the data. With MLC technology, SSDs can write data for up to three times before it has to be written to a different cell. This process extends the life of the device.
