Question $1$

Consider a disk with the following specifications:

$$ Capacity: $8$TB

$$ RPM: $5400$

$$ Average Seek: $5$ms

$$ Max Transfer: $140$MB$/$s

Please compute the following for a transfer of $50$MB bytes:

A$.$ Tseek

B$.$ Trotation

C$.$ Ttransfer

D$.$ Ti$/$o

Question $2$

Assume a drive has been engineered so that the max transfer rate is exactly the max rate at which the data passes under the heads when reading sequentially. If this drive has the following specifications, what$$s the max transfer rate $($in MB$/$s$)?($show your work$--$I need to be able to figure out how YOU figured it out$)$

$$ Capacity: $10$TB

$$ Platters: $7($double sided$)$

$$ RPM: $5400$

$$ Tracks$/$platter side: $1024$

Question $3$

Please define the following terms:

Torn Write

Platter

Track

Track Skew

Disk Head

Disk Arm

Question $4$

Please give a short description of how iNode garbage collection works

Question $5$
