Under the same migration environment conditions, if the two file systems have the same amount of data (both 100GB), their migration rates are the same, regardless of the directory structure or file…

Question

Options

• ATrue
• BFalse

• A
  22% (12)
• B
  78% (42)

Explanation

B is correct because migration rate depends on more than just total data volume - it is heavily influenced by file count, file size distribution, and directory depth. A file system containing millions of small files (e.g., 100GB split across 10 million 10KB files) will migrate far slower than one with the same 100GB stored in a handful of large files, due to the per-file metadata overhead (open, stat, close operations) and filesystem traversal costs multiplied across every file.

Why A is wrong: Assuming equal migration rates ignores the I/O pattern differences between small-file-heavy and large-file-heavy workloads. Small files cause sequential migration tools to spend most of their time on metadata operations rather than actual data transfer, dramatically reducing effective throughput even though total bytes are identical.

Memory tip: Picture moving 100GB as either one large suitcase or 10 million tiny envelopes - same total weight, but stuffing and labeling each envelope takes vastly more time. File count is the "envelope tax" of data migration.
