Operation and Performance Characteristics

 

 

1.7.6.2Error Detection and Correction

The SSD’s error detection code and error correcting code (EDC/ECC) helps maintain data integrity by allowing single or multiple bit corrections to the data stored in the drive’s flash array. If the data in the flash array is corrupted due to aging or during the programming process, EDC/ECC will compensate for the errors to ensure the delivery of accurate data to the host computer. The EDC/ECC engine on the Zeus SSD is capable of correcting up to two bytes in error and detecting up to 3 bytes in error. An extensive retry algorithm is also implemented on all Zeus SSDs, so that single event disturbances such as ESD or EMF occurring during a read operation can be readily overcome.

1.7.6.3Built-in Self Test

During power-up, the SSD’s micro controller tests Zeus controller memory, and then performs a back-end status check to verify proper flash memory controller operations. If a fault condition is detected in the flash memory controller, the SSD’s status is reported as failed.
