High Reliability Flash SSDs, Cards and Modules for Industrial Applications
Industrial Flash SSD Economics - Premium Value for the Higher Quality
Fortasa Industrial SSD Product Family
Frequently our embedded customers compare our Industrial Grade Flash Card, SSD and other storage products with the consumer grade devices typically found on Amazon, or other retail or e-tail sites. The discrepancy in product cost between the Industrial Grade Flash and its consumer brethren is amazingly wide. Considering that every card, whether Industrial or Consumer, has to have a connector, PCB, Flash Controller and NAND Flash component, they are often dumbfounded as to the such sizable price difference.
Given the lack of transparency, I wanted to elaborate on the economics of building an Industrial vs. a Consumer Flash card and the reason for substantial cost difference.READ MORE
CompactFlash Memory Card Interface Modes and Capabilities
Fortasa CompactFlash Card and SATA Adapter
CompactFlash memory cards have been a preferred storage device in many of embedded application. Developers appreciate the compact physical size, high performance interface, environment robustness and ability to easily remove the device even during system operation. Most often the CompactFlash memory card is used as a direct replacement of a conventional magnetic Hard Disk Drive.
Most conventional operating systems, such as Windows or Unix/Linux, have standard device drivers that recognize CompactFlash cards as a HDD and enable transparent interface to the card. This handshaking is performed by the system device driver that reads the CompactFlash card's Device ID table to recognize the Flash card capability and sets up an appropriate level of interface to the card.READ MORE
Resolving CompactFlash Card UDMA Compatibility Issues
CompactFlash cards have been the dominant choice for embedded storage in Industrial Electronic Systems. Attracted by the universal standard in both interface and form factor, the CompactFlash cards have migrated from the storage media predominantly used in consumer devices such as Digital Cameras and MP3 players to Industrial Applications and non-consumer platforms.
In embedded applications, CompactFlash cards are generally used as a higher reliability and more robust storage system to replace traditional Hard Disk Drives. The CompactFlash card includes a TrueIDE interface to emulate the bus interface of the ATA/IDE bus and make Flash storage transparent to the host system.READ MORE
DOD 5220.22-M Requirement - Secure Data Purge From The Flash Storage Device
DoD 5520.22-M Security Data Purge
Another ubiquitous and popular data sanitization method to safely and securely erase sensitive data from a storage device, including Flash SSDs, is DoD 5220.22-M. This method was initially defined by the US National Industrial Security Program (NISP) in the National Industrial Security Program Operating Manual (NISPOM) and is one of the most commonly used data sanitization methods used in data destruction software. Another item to note is that the NISPOM does not define any US government standard for data sanitization. The Cognizant Security Authority (CSA) is truly responsible for data sanitization standards.
The DoD 5220.22-M data sanitization method is implemented in the following way in Fortasa Flash SSDs.:READ MORE
