In write-through caching, data is written simultaneously to both the cache and the underlying disk. This ensures data integrity because the write is not acknowledged until it's safely written to the disk.

Write-back caching offers reduced latency but increases risk of data loss if cache is lost.

Write-through trades speed for security, offering enhanced data security and reducing the risk of data loss during power failures.

NAS systems are purpose-built to handle file sharing and provide:

Centralized file access for multiple clients.

Optimized file sharing through dedicated hardware and software.

Efficient management with file-level protocols (NFS, CIFS/SMB).

FC protocols (Option B) are for block storage, not NAS.

Object ID (Option C) relates to object storage, not NAS.

Speed (Option D): While NAS can offer good speed, its main advantage is shared file access.
