Simplify the following text for a Grade 7 native English-speaking person.
Original: RAID 5 and other non-mirror-based arrays offer a lower degree of resiliency than RAID 10 by virtue of RAID 10 's mirroring strategy . In a RAID 10 , I\/O can continue even in spite of multiple drive failures .
Simplified: Like RAID 1 , it only uses two disks , but it does both striping and mirroring ( similar to RAID 10 ) .
