Industrial SSDs

Yes, many industrial flash storage solutions offer a fixed BOM (Bill of Materials).

This means that the hardware and firmware components of the product remain unchanged throughout its entire lifecycle. This ensures:

• Consistent performance: No unexpected changes with firmware or hardware updates.
• Long-term availability: Particularly important for projects with certification or validation requirements.
• Stable supply chain: Minimized risk from sudden changes in production.

The fixed BOM is a key aspect in ensuring reliability and predictability in industrial applications.

• TBW (Total Bytes Written):
  Indicates the maximum amount of data that can be written over the lifetime of a flash storage device. It is a measure of durability and is given in terabytes. A higher TBW value means a longer lifespan.
• MTBF (Mean Time Between Failures):
  Describes the average operating time between two failures. It is given in hours and provides insight into the product’s reliability. Industrial flash storage typically has an MTBF of 2 million hours or more.

Both values are crucial for selecting the appropriate flash storage for applications with high demands.

The read and write speeds vary depending on the flash type, interface, and manufacturer:

• SATA III: Up to 550 MB/s (Read) and 500 MB/s (Write).
• NVMe (PCIe Gen3): Up to 3,500 MB/s (Read) and 3,000 MB/s (Write).
• NVMe (PCIe Gen4): Over 7,000 MB/s for reads and up to 6,000 MB/s for writes.

Please note that actual performance also depends on the storage architecture and working conditions.

The differences lie in how data is stored, which affects performance, durability, and cost:

• SLC (Single-Level Cell):
  Stores 1 bit per cell. Offers the highest reliability, durability, and write speed, ideal for critical applications.
• MLC (Multi-Level Cell):
  Stores 2 bits per cell. Provides higher storage density with moderate reliability and performance. Suitable for semi-industrial applications.
• TLC (Triple-Level Cell):
  Stores 3 bits per cell. Offers high storage capacity at a low cost but with limited durability and performance. Primarily used in consumer devices.
• pSLC (Pseudo-Single-Level Cell):
  Uses MLC technology but stores only 1 bit per cell, significantly improving durability and performance. A cost-effective alternative to SLC for industrial applications.

The choice of the right flash type depends on the requirements for durability, performance, and budget.

Industrial-grade flash storage is specifically designed for demanding environments that require reliability, durability, and stability. Unlike commercial-grade storage solutions, they offer:

• Increased robustness: Higher resistance to extreme temperatures (-40°C to +85°C), shocks, and vibrations.
• Consistent performance: Longer lifespan through specialized wear leveling technologies and lower bit error rates.
• Long-term availability: Stable supply chain and long-term product specifications for industrial applications.
• Data security: Enhanced error correction mechanisms (ECC) and protection against data loss during power outages (Power-Loss Protection).

These features make industrial-grade flash solutions the ideal choice for applications like industrial automation, medical devices, transportation, or military systems.
