What does the term 'wear leveling' refer to in SSDs?
A. Improving read speed
B. Evenly distributing write and erase cycles across memory blocks to extend lifespan
C. Defragmenting the drive
D. Reducing power consumption
Answer: Option B
Solution (By JKSSB Mock Tests)
Wear leveling is a technique used in flash memory storage to ensure that all memory blocks experience roughly equal write/erase cycles, preventing premature failure of heavily used blocks.
