SSD350 series drives for reliable operation in industrial conditions

By | January 14, 2020

The SSD350 series of drives introduced to the CSI offer, and produced by one of the world's leading manufacturers Silicon Power is a solution dedicated to such industries as: transport or automation.

Silicon Power SSD350 2.5 "SATA III SSDs are mass storage devices based on flash memory technology 3D NAND. The SSD350 series includes the following models that meet different requirements:

Series SSD350R Rugged based on the SM2258H controller has:

  • Built-in Advanced PFP (Power Failure Protection) technology to eliminate the risk of damage or loss of data caused by unexpected power outages or voltage drops
  • The Power Shield function using the controller software and power circuit monitoring algorithm to protect the SSD from failure and securely write data from the DRAM cache to the flash memory controller in case of sudden voltage changes
  • This allows better data protection in the event of a power outage. The function is activated before the standard write protection mode, thanks to which data integrity is maintained. What's more, this feature also protects against media damage associated with power off.

Series SSD350S Performance based on the SM2258H controller is a model equipped with Power Shield functions that uses the controller software algorithm and power circuit monitoring to safely write data from the DRAM cache to the flash memory controller.

Series SSD350E Embedded based on the SM2258XT controller is a disk without DRAM memory but with Power Shield functions shielding the architecture of the system's software.

All SSD350 series products are equipped with LDPC ECC to correct 120 bits for each 1024 bytes data as well as in function RAID Block / Page, guaranteeing durability 3K PE cycles with 3D NAND. They also have the latest Direct-To-TLC and SLC cache architecture as well as external DRAM memory, which allows for optimal, long-lasting read and write performance and reduce write amplification to provide even greater TBW strength; greater than with memories equipped with 2D MLC.

StaticDataRefresh technology monitors voltages and provides quick refresh when needed to maintain high read performance over time and maintain data integrity.

The SSD350S / R series can additionally include hardware write protection and secure erase via an optional connector.

It can also provide write protection for the software and the secure erase function with appropriate software if needed.

The SSD350S / R series is equipped with an integrated power management system PMU industrial grade (Power Management Unit), which ensures greater reliability of the power supply structure compared to traditional discrete systems. It also comes with complete protection from OVP. OCP, function Surge Rejection and In-Out Short Protection, which provides a higher level of protection compared to traditional fuse design.

Early withdrawal of weak blocks and the global consumption balancing algorithm ensures equal use of flash memory cells to extend the life of SSDs.

Silicon Power also supplies the SSD550 S / R series equipped with pSLC, allowing to achieve 30,000 PE cycles to meet the requirements of applications requiring high strength.
