看到這一段有點看不懂
內文是
As the number of disks grows by 1
當DISK多一顆
the number of access required to calculate a parity word in RAID 3
also grows by 1.
在RAID 3中，需要計算parity的disk也會多1顆
in contrast, RAID 4 and 5 continue to access only existing
values of data being stored.
這段看不懂
thus,as the number of disk grows , RAID 3 performance will continue to
degrade while RAID 4 and 5 will remain constant.
當disk數一直增加，RAID3效能會一直掉，RAID 4 and 5 會維持固定
怎麼翻都怪怪的 麻煩大家指點了
