CREATE TABLE table_71289 ("Device" FLOAT, "Device type" TEXT, "Capacity [MB]" TEXT, "Avg seek time [ms]" TEXT, "Avg rotational delay [ms]" FLOAT, "Avg transfer rate [kB/s]" FLOAT)

What is the avg seek time for a device that is less than 3231?
SELECT "Avg seek time [ms]" FROM table_71289 WHERE "Device" < '3231'
SELECT "Avg seek time [ms]" FROM "table_71289" WHERE "Device" < '3231'
