Which are the reliability technologies for HSSDS?

Question

Options

• ARAID
• BBad block management
• CWear leveling
• DPower failure protection

• A
  16% (4)
• B
  84% (21)

Explanation

Bad block management, wear leveling, and power failure protection are all reliability technologies that address the specific vulnerabilities of NAND flash memory used in solid-state storage. Bad block management detects and quarantines defective memory cells, rerouting data to healthy areas to prevent data loss. Wear leveling distributes write and erase operations evenly across all flash cells, compensating for the fact that each cell has a finite number of write cycles before it degrades. Power failure protection uses capacitors or similar mechanisms to flush in-progress writes to non-volatile storage when power is suddenly cut, preventing data corruption.

RAID (option A) is incorrect because it is a system-level redundancy strategy applied across multiple drives - it is not an intrinsic reliability feature of solid-state storage itself, making it the distractor here.

Memory tip: Think of B, C, and D as technologies that fight the three natural enemies of flash cells - bad cells, uneven wear, and sudden power loss. RAID is something you do to drives, not something built into a drive.
