Understanding Defragmentation and Modern File Systems

Why is defragmentation unnecessary for SSDs?

• Defragmentation improves SSD performance.

• SSDs can access data spread across the disk at the same speed.

• SSDs have unlimited write cycles.

• SSDs are immune to data fragmentation.

What is the primary function of an extent in modern file systems?

• To compress files for more storage space.

• To reserve a continuous area of the disk for a specific file.

• To automatically defragment files.

• To increase the speed of data retrieval.

How does file compression help in reducing fragmentation?

• By increasing the size of files.

• By creating larger gaps for new files, reducing fragmentation.

• By automatically defragmenting files.

• By converting files into a different format.

What is delayed allocation in file systems?

• A way to automatically defragment files.

• A technique to hold data in memory before writing to disk.

• A method to compress files before writing.

• A process to increase disk space.

What feature in Mac OS claims to reduce the need for manual defragmentation?

• Delayed allocation

• Transparent defragmentation

• File compression

• Extent allocation
