Which of the following is a disadvantage of RAID 10?
The correct answer is D. Higher cost. A major disadvantage of RAID 10 is its significantly higher cost due to the requirement for a minimum of four disks and only 50% of the raw storage capacity being usable.

Why each option
A major disadvantage of RAID 10 is its significantly higher cost due to the requirement for a minimum of four disks and only 50% of the raw storage capacity being usable.
RAID 10 generally offers excellent performance for both read and write operations because it combines the benefits of striping for speed and mirroring for faster reads.
RAID 10 provides robust fault tolerance, capable of surviving multiple disk failures as long as the failures do not occur within the same mirrored pair.
RAID 10 is a widely supported and commonly implemented RAID level across various hardware and software RAID controllers due to its balance of performance and fault tolerance, especially in high-performance environments.
RAID 10 combines RAID 1 (mirroring) and RAID 0 (striping), requiring at least four disks. Because data is mirrored, only half of the total raw disk capacity is available for storage, making it a more expensive solution per usable gigabyte compared to other RAID levels like RAID 5 or 6.
