[Year 12 IT Apps] BACK UP MEDIA

[Rob Minato]

The differences are rapidly diminishing. HDD were much cheaper but ssd is closing the gap. Today it's $110 for a 1Tb hdd and $185 for a 240 Gb SSD.
Sustained data rates are twice as fast for ssd.

SSD and flash (in same block on p290) are much the same thing albeit speeds are much different.

I mourn the loss of thousands of precious lives, but I will not rejoice in the death of one, not even an enemy. Returning hate for hate multiplies hate, adding deeper darkness to a night already devoid of stars. Darkness cannot drive out darkness: only light can do that. Hate cannot drive out hate: only love can do that.
