Question

hard disk drive has 16 platters, 8192 cylinders, and 256 4KB sectors per track. The storage capacity of this disk drive is at most Select one: a. 32 GB. b. 128 GB. c. 128 TB. d. 32 TB.

Answer 1

Answer:

B

Explanation:

Here, we want to calculate the storage capacity of the disk drive.

We proceed as follows;

Per track capacity = 4 * 256 KB = 1024 KB = 1 MB

per platter capacity = 1 MB * 8192 = 8192 MB

total capacity = 16 * 8192 MB = 131072 MB

converting total capacity to GB,

1024 MB = 1 GB

thus, 131,072 MB to GB would be;

total capacity =131072/1024 = 128GB
