Response time
Response time measurements are taken with nominal power at 25°C ambient temperature. The typical values in the table
below are defined as follows:
• Page-to-page response time is an average of all possible page-to-page accesses for a sequentially preconditioned
drive.
• Average response time is a true statistical random average of at least 5000 measurements of accesses between pro-
grammable pages on a randomly preconditioned drive.

1.
Execution time measured from receipt of the Command to the Response.
2.
Assumes no errors.
3.
Typical response times are measured under nominal conditions of temperature and voltage as measured on a representative
sample of drives.
These drives are designed to provide the highest possible performance under typical conditions. How-
ever, due to the nature of Flash memory technologies there are many factors that can result in
values different than those stated in this specification.
