De givna valen är Single, RAID 0, LARGE och RAID 1. Såsom antingen högre hastighetsdatatransmission, dataspegling för mer tillförlitlighet, en upptäckt av
It combines the same advantages of RAID 0 (speed) and RAID 1 (safety), but in different way. RAID 1+0 creates a large stripe of small mirrors. After failure of a disk, while it is being replaced, only the small fragment of a whole array is rebuilt. Två eller flera RAID 0-enheter sätts samman med RAID 1. Sämre kraschsäkerhet än 1+0 eftersom det räcker med att en disk i varje RAID 0-enhet går sönder, därför mindre använd. Även för den vanligaste konfigurationen, fyra diskar sammansatta i par, är 0+1 mindre tillförlitligt än 1+0.

In Raid 0+1, striping occurs first and then mirroring. RAID (Redundant Array of Independent Disk) are the group of disk organisation techniques evolved to deal with the reliability and performance. The fundamental difference between the RAID 0 and RAID 1 is that the RAID level 0 does not contain redundant data, in fact, it uses striping. 2016-10-06 RAID Implementation Types RAID 0+1.

In general, when you need performance over data redundancy, RAID 0 is your choice, while RAID 1 is the choice when you’re handling mission-critical data where redundancy is a must. Del 1: Raid 0 vs. Raid 1: Spot Main Differences. Här är en detaljerad jämförelse av raid 0 och raid 1-matriser.
Raid 0+1 vs Raid 1+0 (Probability of Failure) Here's a little bit of math that should show the differences in rates of failure. For simplicity, let's assume there is an even number of disks. In both array configurations, each disk is broken up into blocks. In Raid 0+1, striping occurs first and then mirroring.
퍼포먼스 및 용량 위주로 구성한다면 디스크 3개를 raid 0으로 묶은 스트라이프 볼륨 2개를 raid 1로 미러링 한다. 이 경우 사용 가능한 총 용량은 3tb가 된다. 2021년 2월 26일 RAID 10이나 RAID 01과 같이 두 가지 방식을 혼용하는 경우도 있다. RAID의 존재 의의는 저장장치의 가용성과 성능 향상에 있지 데이터 백업의 용도 2018년 8월 31일 대용량의 단일 볼륨을 사용하는 효과.
In raid 0+1 the first disk failure fails all disks in that stripe, the failure of any subsequent disk means a member of the other stripe has failed and so data access is lost. Two disk failures = total data access losss. In raid 1+0 there is potential for loss of upto half the members and for data access to remain.
