2.6Access time

Access measurements are taken with nominal power at 25°C ambient temperature. All times are measured using drive diagnostics. The specifications in the table below are defined as follows:

Page-to-page access time is an average of all possible page-to-page accesses in both directions for a sequentially preconditioned drive.

Average access time is a true statistical random average of at least 5000 measurements of accesses between programmable pages, less overhead, on a randomly preconditioned drive.

Note. These drives are designed to provide the highest possible performance under typical conditions. However, due to the nature of Flash memory technologies there are many factors that can result in values different than those stated in this specification.

Power-on to Ready for non-media related commands is defined as the time that it will take the drive to respond from the application power until it is ready to accept commands from the host that do not require access to the flash media. In some cases the drive may accept media access commands during this time, but the commands will not be completed or status returned to the host until the media can be accessed safely. Commands such as Check Power and Identify are examples of non-media related commands.

Power-on to Ready for media related commands is defined as the time that it will take the drive to respond from the application power until it is ready to accept commands from the host that require access to the flash media. Commands such as FPDMA Read Extended and FPDMA Write Extended are examples of media related com- mands. This value includes the time needed to charge the Power Loss Data Protection Circuit to a level that is adequate to protect customer data from unexpected power loss
