raid for comptia

Here are the RAID types in CompTIA

Table of RAID 0, 1, and 5

RAID 0 is writing data to two drives at once. Very fast half data on one drive half on the other. no fault tolerance cause one drive down and lose half of the data. 0 for no fault tolerance

RAID 1 is first level of fault tolerance. You literally copy the same data to both drives. If one dive goes down, no problem the other is a duplicate

RAID 10 means you put half on one drive and half on the other and make a copy of each half. Now you have speed plus a duplicate if one drive crashes.

CompTIA 220-11-1 exam objective. If a term is here, you need to know it for the test.
