Time taken to move from one cylinder of a HDD to another is called ______________.
Time taken to move from one cylinder of a HDD to another is called ______________.
The correct option is B Average seek time
Time taken to move from one cylinder of a HDD to
another is called Average seek time.
A hard drive's average seek time is typically
calculated by approximating how long it takes to look for data over one-third
of the hard drive's tracks. Though the average seek time is the most common way
to measure this value, it can be done in two other ways too: track-to-track and
full stroke.
Seek Time is measured defines the amount of time it
takes a hard drive's read/write head to find the physical location of a piece
of data on the disk. Latency is the average time for the sector being accessed
to rotate into position under a head, after a completed seek.
Disk access times are measured in milliseconds
(thousandths of a second), often abbreviated as ms. Fast hard disk drivesfor
personal computers boast access times of about 9 to 15 milliseconds. Note that
this is about 200 times slower than average DRAM.
Data transfer rate is an important indication to
measure hard disk performance. It can be divided into external transfer rate
and internal transfer rate. External transfer rate is commonly called burst
data transfer rate or interface transfer rate. It refers to the speed of
outputting data from the hard disk cache.
