Solid state storage solutions deployed by OEMs need to last 5 to 10 years or more and perform in every type of usage model and environment. SolidStor technology makes designers, supply chain managers and OEMs confident that their storage system choice exceeds the high performance, high reliability and low total cost of ownership requirements for demanding applications in the netcom, industrial, embedded computing, data center, military and medical markets.
Benefits of SolidStor
WD offers a wide array of patented and patent-pending silicon-level, system-level and firmware-level technologies to ensure its SiliconDrive products deliver industry-leading data integrity. These include:
- Best-in-class advanced ECC algorithms
- Patented wear-leveling technology
- Bit-flip error elimination
- Patent-pending data refresh technology
Advanced Error Correction Code (ECC) Algorithms
SolidStor technologies add redundancy to the data stream that is transferred by a host system to a SiliconDrive. When noise or some form of interference causes data distortion, these proprietary technologies detect and correct the inevitable errors.
Patented Wear-Leveling Algorithms
WD's patented wear-leveling algorithm writes data evenly over the entire SiliconDrive, resulting in the longest possible drive life. A SiliconDrive solid state drive is specifically engineered to exceed the exacting requirements of OEMs who demand high reliability in a wide variety of operating, environmental and duty-cycle applications.
In contrast, traditional flash card wear-leveling algorithms do not write evenly over the entire card. The expected life of traditional flash cards is directly related to the amount of static data present - the more static data, the shorter the card life.
Bit-Flip Error Elimination
Smaller manufacturing process geometries combined with increasingly complex chip designs is resulting in increased sensitivity to transient bit-flip errors. Transient bit-flip errors occur when a cell's state is unintentionally flipped from a 1 to a 0 or a 0 to a 1. If these unintentionally flipped data bits are not detected and corrected by ECC (error correction code) they cause unpredictable behaviors resulting in corrupt data, host system downtime and fatal data errors.
Industry-Leading Data Integrity
Solid state storage solutions are subject to physical degradation that can eventually lead to failure. The two end-of-life parameters that determine the performance of a solid state storage system are endurance and data retention.
Endurance specifies the cumulative program/erase cycling capability of any individual sector in a solid state storage device. Data retention specifies the maximum period of time, after programming, that data can be expected to be retrieved from a solid state storage device. These two parameters are not mutually exclusive and it is paramount to understand their complex inter-relationship to design a reliable solid state storage solution.
Fast Data Transfer
SiliconDrive solid state drives are designed to run at high internal clock speeds to manipulate single sectors of data with high efficiency. The result is fast read/write performance in both transactional applications and large file streaming applications.
Most traditional storage products are designed for the consumer electronics or personal computer markets and therefore focus on maximizing large file transfer performance rather optimization for small file transactional applications. SiliconDrive solid state drives are specifically designed to support the broad range of small and large file transfer requirements of OEM applications. |
