FrameSolid
With the advancement of solid-state drive (SSD) technology, there is an increasing demand for long-term, stable write performance. While traditional SSDs provide high-speed read and write performance initially, their performance often degrades significantly over time, posing a major challenge for applications that require continuous, stable operation. FrameSolid technology was developed to address this issue by ensuring that SSDs maintain stable performance during prolonged use, making it particularly suitable for applications that demand reliable storage.
Advanced LDPC
Advanced Low-Density Parity-Check (LDPC) codes are sophisticated error-correction algorithms designed to enhance data reliability in high-performance storage and communication systems, such as SSDs and wireless networks. The core principle of LDPC involves using a matrix-based method to detect and correct errors, ensuring data integrity during transmission or storage.
Selected SSD Controller
The latest Industrial SSD series is equipped with an advanced LDPC ECC engine capable of correcting up to 120 bits per 1024 bytes of data. Combined with a Block/Page RAID function, this design ensures up to 3,000 program/erase (PE) cycles of endurance using 3D NAND technology.
Conformal Coating
Conformal coating is a protective layer applied to printed circuit boards (PCBs) to shield them and their components from environmental damage and corrosion. Typically applied with a thickness of 30-210μm, the coating conforms closely to the shape of the PCB and its components, covering solder joints, exposed leads, traces, and other metalized areas. By enhancing resistance to moisture, pollution, dust, and chemical contaminants, conformal coating helps extend the lifespan of electronic products.
Underfill
Underfill technology is a cutting-edge solution designed to enhance the reliability of electronic components. The process involves injecting a specialized filling material between the bottom of components on a PCBA (Printed Circuit Board Assembly) and the substrate.
Wide Temperature
We are pioneers in developing high-performance products designed to endure extreme temperatures. Leveraging our Advanced Sorting technology, we have built a customized die bank database tailored for a variety of NAND chip brands and types. Our top-tier industrial solutions, including DRAM modules, operate reliably in temperatures as low as -40°C and as high as 105°C. These robust products are vital in critical sectors such as industrial processing, logistics, and telecommunications. To ensure their durability, we subject them to rigorous 3000 Power Cycle tests.
SMART IoT
S.M.A.R.T, short for Self-Monitoring, Analysis, and Reporting Technology, is a monitoring system designed for early error detection in flash storage devices like solid-state drives (SSDs). SSDs use NAND flash memory, which stores data by moving electrons. However, repeated write cycles can gradually degrade the NAND chips, limiting the lifespan of the drive.
Thermal Throttling
Thermal throttling is a technology designed to dynamically regulate the operating frequency of devices, such as SSDs, to prevent overheating and maintain stable performance. This mechanism leverages real-time temperature monitoring through dual thermal sensors placed on both the PCB and the controller. Integrated with the SP SMART toolbox, these sensors continuously monitor the SSD's temperature to detect potential overheating.
End2End Protection
End-to-End (E2E) technology is a comprehensive approach to testing and monitoring systems from start to finish. Its primary goal is to simulate real user interactions and ensure the seamless operation of the entire system. By replicating user scenarios, E2E testing verifies whether various components and processes in the system work cohesively.
Advanced Power Shield
The Power Shield (PS) function activates when the external voltage drops to a critical level, such as from 3.3V to 2.7V. At this point, the voltage detection circuit inside the SSD controller triggers the power protection mechanism.
Write Protect
Write Protect can prevent important data stored on a solid state drive (SSD) from being accidentally changed or deleted. When activated, Write Protect mode only allows reading of data; writing and deleting are blocked.
PFP
SP Industrial's complete series of solid-state drives are equipped with a power shielding firmware architecture that protects them by sensing unstable voltage and powering down to stop receiving host commands.
SP Industrial's R series of SSDs uses Advanced PFP with industrial-grade polymer capacitors to allow more time for data to be flushed from temporary memory (DRAM cache) to permanent storage (FLASH) during unexpected power loss situations.
Quick Erase
Reliably erasing data from storage devices is critical for secure data management. Solid state drives(SSDs) differ from hard disk drives in how they store and manage data using flash memory instead of magnetic disks.
AES 256
AES 256 (Advanced Encryption Standard with a 256-bit key) is a powerful encryption technology used to keep data secure and confidential. It works by encrypting data and allowing it to be decrypted when needed.
TCG OPAL
Self-Encrypting Drives (SEDs) integrate hardware-based encryption to secure data at rest. A Media Encryption Key (MEK) encrypts and decrypts data, protecting sensitive information in applications like IoT, industrial systems, and medical devices.
SP Toolbox
Understanding SSD Endurance
Two key metrics are used to estimate SSD endurance:
Total Bytes Written (TBW): Calculated using the formula:
TBW = Physical Capacity × NAND Program/Erase Cycles ÷ Write Amplification Factor ÷ Wear Leveling Factor.
Drive Writes Per Day (DWPD): Defined as:
Sorting
To meet the needs of industrial customers operating under various temperature conditions, SP employs Advanced Sorting Technology (AST) for NAND Flash testing and classification. This technology accurately evaluates the durability and stability of NAND Flash and classifies them based on test results to meet the strict requirements of wide-temperature applications.
Garbage Collection
Solid-state drives (SSDs) utilize NAND flash memory to store data, employing a process managed by the controller to ensure efficient storage and retrieval. Unlike traditional storage methods, SSDs cannot directly overwrite old data with new data. Instead, the existing data in the relevant block must first be erased before new data can be written. This process is facilitated through a mechanism known as Garbage Collection.
Bad Block Management
Bad Block Management is a mechanism used by the controller in flash memory to detect and handle bad blocks. It identifies and marks defective blocks, ensuring they are not used for data storage again. To maintain data reliability, the controller replaces bad blocks with reserved spare blocks, which helps prevent data corruption and improves the overall reliability and lifespan of the memory.
pSLC
SP Industrial bridges the gap between SLC and MLC/3D TLC solutions with pseudo-SLC (pSLC) Flash, a more advanced variant of MLC/3D TLC. pSLC offers faster speeds, higher program/erase cycle endurance, and better reliability than standard MLC/3D TLC, while being more cost-effective than SLC. It operates similarly to SLC but has fewer program/erase cycles, making it an efficient choice for applications demanding high endurance.
Wear Leveling
Wear leveling is a key solution for managing the limited program/erase (P/E) cycles of NAND flash memory. By evenly distributing wear across memory blocks, wear leveling extends the lifespan and reliability of flash devices. SP Industrial SD and microSD cards incorporate three wear leveling techniques: dynamic, static, and global.
