2.5 SSD M.2 NVME 2280 Solid State Drive Laptop Interface OEM Customization

Many friends may not be familiar with what SSD is, but in fact, SSD is also a solid state drive, abbreviated as a solid state drive. A solid state drive is a hard disk made of a solid-state electronic storage chip array, consisting of a control unit and a storage unit (FLASH chip, DRAM chip). Solid state drives are identical to regular hard drives in terms of interface specifications, definitions, functions, and usage methods, as well as in terms of product appearance and dimensions. Widely used in military, vehicle, industrial control, monitoring, network monitoring, network terminals, power, medical, aviation, navigation equipment and other fields.
What is SSD? What is the classification?
The operating temperature range of its chips is very wide, including commercial products (0-70 ℃) and industrial products (-40~85 ℃). Although the cost is high, it is also gradually becoming popular in the DIY market. Due to the differences between solid-state drive technology and traditional hard drive technology, many emerging memory manufacturers have emerged. Manufacturers only need to purchase NAND memory and use appropriate control chips to manufacture solid-state drives. The new generation of solid-state drives generally adopts SATA-2 interface, SATA-3 interface, SAS interface, MSATA interface, PCI-E interface, NGFF interface, CFast interface, and SFF-8639 interface.
classification
There are two types of storage media for solid-state drives: one uses flash memory (FLASH chip) as the storage medium, and the other uses DRAM as the storage medium.
Solid state drives based on flash memory
Flash based solid-state drives (IDE FLASH DISK, Serial ATA Flash Disk): use FLASH chips as storage media, which is also commonly referred to as SSDs. Its appearance can be made into various shapes, such as laptop hard drives, micro hard drives, storage cards, USB drives, and other styles. The advantage of this SSD solid-state drive is that it can be moved and data protection is not controlled by power, making it suitable for various environments. However, its lifespan is not high, making it suitable for individual users. In flash based solid-state drives, storage units are divided into two categories: SLC (Single Layer Cell) and MLC (Multi Level Cell). The characteristics of SLC are high cost, small capacity, but fast speed, while the characteristics of MLC are large capacity, low cost, but slow speed. Each unit of MLC is 2 bits, which is twice as much as SLC. However, due to the large amount of data stored in each MLC storage unit and its relatively complex structure, the probability of errors increases and error correction is necessary. This action results in its performance significantly lagging behind the simple structure of SLC flash memory. In addition, the advantage of SLC flash is that it can replicate up to 100000 times, which is 10 times higher than MLC flash. In addition, in order to ensure the lifespan of MLC, the control chip verifies and uses intelligent wear balance technology algorithms, so that the number of writes to each storage unit can be evenly divided
Spread and achieve a time between failures (MTBF) of 1 million hours.
Solid State Drive Based on DRAM
Solid state drives based on DRAM: Using DRAM as the storage medium, the current application range is relatively narrow. It imitates the design of traditional hard drives, can be set and managed by the file system tools of most operating systems, and provides industry standard PCI and FC interfaces for connecting hosts or servers. The application methods can be divided into two types: SSD hard disk and SSD hard disk array. It is a high-performance memory with a long lifespan, but the downside is that it requires an independent power supply to protect data security.
What is SSD? Interface type:
The mainstream interface types for SSD solid-state drives are:
SATA interface: SATA SATAII SATA3.0
PATA (IDE interface): IDE44PIN IDE40PIN
PCI-E interface: mSATA PCIE (IDE) PCIE (SATA) ZIF: ZIF interface, etc
The above is a brief introduction to what SSD is. Through this article, we hope everyone can have an understanding of SSD.
