What is the approximate data transfer rate of a SATA III (6 Gbps) interface?
A. 600 MB/s
B. 3 Gbps
C. 150 MB/s
D. 6 GB/s
Answer: Option A
Solution (By JKSSB Mock Tests)
SATA III has a maximum theoretical bandwidth of 6 Gbps, which translates to about 600 MB/s (due to 8b/10b encoding overhead). Actual speeds may be lower.
Explanation:
CD-RW discs use a phase-change material that can transition between crystalline (reflective) and amorphous (absorbent) states via laser heating to clear or write data.
