A RAID 5 array is built from four 2 TB disks. What is the usable storage capacity of the array? / चार 2 TB डिस्क से RAID 5 ऐरे बनाया गया। ऐरे की उपयोगी भंडारण क्षमता कितनी है?

8 TB

4 TB

6 TB
4.
2 TB
Correct Answer: 6 TB
RAID 5 reserves the equivalent of one disk for distributed parity, so usable capacity is (4 − 1) × 2 TB = 6 TB. / RAID 5 एक डिस्क के बराबर distributed parity रखता है; उपयोगी क्षमता (4 − 1) × 2 TB = 6 TB। Option (a) is the trap — it ignores the parity overhead entirely.
