0.022 seconds does it take for the raid 5 to read this data for the raid 6.
What is data?
In a computing process, data can be employed as a variable. Data can reflect either abstract concepts or tangible measures. Data are widely employed in scientific study, finance, and almost every other type of human organisational activity.
Reading speed for each Raid's(Raid1 and Raid2) = 48 Mega Byte/sec.--(1)
When in disk failure read performance is degraded by = 12% that is 12/100 × 48
= (12/100) × 48
= 5.76 Mega Byte/sec (Must be subtracted from (1) to find original speed.)
= 48 - 5.76
= 42.24 MB/sec (Read speed of both Raid's in case of 1 disk failure in each of the arrays) ---(2)
From (2) if one disk fails read speed is 42.24 MB/sec
If one more disk fail then this read speed again degraded by 12%
12/100 × 42.24
= 5.07 (This should be subtracted from (2) to get the final speed)
=42.24 - 5.07
= 37.17MB/sec---(4)
To read (3) that is 0.85 MB both raid tooks
=1/37.17 × 0.85
= 0.022 seconds
