Error Rates
Table 3 lists the error limit specifications. When all data correction mechanisms are enabled, the error
rate will be sustained through all operating temperature ranges as specified in the upcoming sections.
Table 3.
Error Limits
Built-In Self Test (BIST)
The micro-controller tests the controller memory during power-up, 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 status of the SSD is reported as failed.
Mount Time
The amount of time required to initialize and mount the SSD varies according to the operating system
(Windows
®
, Linux
®
, etc.) environment and the storage capacity of the drive.
Seek Time
The SSD has no moving read/write heads or rotating platter. There is no seek time or rotational
latency issues. This improves transaction throughput, particularly for applications that are configured
to take advantage of the characteristics of the drive.
Data Transfer Rates
The data transfer rate of the SSD depends on the flash controller/flash memory configuration of the
drive. The scalable architecture of the drive is capable of accommodating sustained and burst data
transfer rates as outlined in Table 4.
