Suppose the embedded flash memory modules of question 34 were to be incorporated in standard 3.5 inch form factor disk drive housing. How much data could be stored assuming that half the volume would be taken up by cooling heat sinks and interface circuits?
What will be an ideal response?
The dimensions of a typical hard drive are 10.2 cm × 14.7 cm × 2.6 cm = 389.8 cm3. Half this is available for storage; that is 194.9 cm3. The volume of a single 128 GB chip is 17 × 22 × 1.4 mm = 523.68 mm3 (or 0.52368 cm3). The number of chips that you can fit into 194.9 cm3 is 194.9/0.52368 = 372. The total capacity is 372 ×
128 GB = 47.6 TB.
