seek time[′sēk ‚tīm]
The time required for the access mechanism of a random-access storage device to be properly positioned.
seek time (storage)
The time it takes for a disk drive
to move its
head(s) from one track
to another. The seek time depends on
the power of the servo, the mass of the heads, the number of
tracks traversed and the time taken to position the heads over
the target track accurately enough to start data transfer.

, minimum seek time
, maximum seek time
seek timeThe average of the time it takes to move the read/write from its current location to a particular track on a disk. In 1998, Seagate introduced its line of Cheetah hard disks with 5ms seek time. Ten years later, it was down to an average of 3.9ms. See access time.

With the FalconStor NSS appliance fronted by the Violin 1010 memory appliance, production performance of data-centric applications is unleashed from disk seek
times, since Tier-0 memory enables faster processing of terabyte-scale datasets.
They make the distinction between disk seek
time at half that of IBM disks and disk access time--the two are not the same.
The cache reduces mechanical disk seek
and latency periods, optimizing physical disk I/O access patterns and reducing the number of drive accesses, which are the bottlenecks in most RAID storage systems.
