◉ what is an mSATA Answer: A SATA cable often used to connect
SSD to connect to a PCs power port as an alternative.
◉ Downsides to using SATA interface to connect an SSD Answer: The
interface can bottleneck SSD b/c it cant support the transfer speed
of the SSD of up to 6.7GB

◉ Define HDD Answer: A hard disk drive that store data on a metal
or glass platter.
◉ What is the performance rating scale for HHD drives Answer:
15,00; 1000 High performance
7,200; 5400 Average performance
◉ what is Access time Answer: the delay as the read/write head
locates a particular track position
encompasses the total time for a computer to read/write required
data
impacted by the sector location process (rotational latency) on the
drive.
◉ what is Seek time Answer: the time it takes to move from one
point to the pint data resides.
