1Reliability with Power Failure Protection(PFP)
Embedded system operation puts great emphasis on reliability and durability for it generally runs for 24/7 and often in a harsh environment. To survive in such critical operating conditions, Industrial SSDs are generally adopted for safer data maintenance purpose, which is essential for mission-critical applications since the consequences of data loss or corruption would lead to great damage to the whole system operation. To provide a more reliable storage solution, SP industrial SSDs apply the Power Failure Protection (PFP) to prevent potential data loss or corruption caused by unexpected power failure, which may be the greatest risk to embedded computing system.

SP SSD devices are equipped with advanced PFP technology to minimize, even eliminate, the potential damages posed by accidental power loss. The PFP is able to perform two measures before and after the unplanned power failure happens-pre-failure alert and post-failure power hold-up. The pre-failure alert is a precaution mechanism that the SSD is able to monitor each circuit and take instant actions once a possible power failure is detected. When it comes to such situation, the PFP will send an early warning to the SSD controller to stop receiving new data and, at the same time, accurately transfer in-flight data to the flash memory. Once the power failure does happen, the SSD will carry out the secondary measure with a voltage hold-up circuit to provide the DRAM cache buffer sufficient time to collect and deliver the data to the flash memory safely. Also, the SSD will manage to restore the link table of lost data on the next power up.

2Flexibility with Pseudo-SLC Flash and Industrial Temperature Solution
SP provides flexible product combinations with different levels of NAND Flash and wide-temperature solutions to meet each specific industrial application need. Customers can find the best embedded solution from SP’s various products portfolio according to their technical requirements, enterprise storage environments and budget plans.
Pseudo-SLC Flash
SP offers various NAND flash types for different application needs. In addition to SLC and MLC flash, which are commonly known by most customers, SP also adopts the pseudo-SLC flash that enables firmware adjustment to improve the speed performance as well as the durability when compared with MLC. Pseudo SLC is a variant of MLC that it rearranges its mechanism to store 1 bit per cell instead of 2 bits per cell like MLC does. Therefore, the pseudo SLC is able to deliver superior read and write speeds and higher endurance capability with up to 10K Program Erase cycles whereas MLC is only rated for 3K Program Erase cycles. The pseudo SLC shares similar performance capabilities as SLC which are much better than MLC but still less than SLC. However, the cost of pseudo SLC is much less than that of SLC to offer customers a balanced alternative that takes performance, durability and cost into consideration.
Industrial Temperature Solution

SP presents multiple products to support different temperature applications with normal, extended and industrial temperature solutions. Now that the normal temperature (0°C to 70°C) and extended temperature (-25°C to 85°C) solutions can satisfy most industrial operation scenario, SP intends to fulfill each customer’s requirement by further providing the top-grade products with industrial-temperature solution that it enables long-term operations under -40°C to 85°C temperature range to guarantee durable and reliable performances even under harsh environmental conditions. The industrial temperature solution is especially designed for rigid requirements of outdoor system operations, such as Transportation and telecommunication applications.

3Data Security with AES 256 Encryption

SP SSD devices apply the AES 256-bit encryption technology to promise higher data security. In the process of data transmission from system to memory, the AES Engine will automatically proceed Full Disk Encryption (FDE). And while the transmission is from memory to system, the data will be decrypted automatically without any leakage of classified information even if the hardware is damaged or broken.
