RAID 1 consists of an exact copy (or mirror) of a set of data on two or more disks; a classic RAID 1 mirrored pair contains two disks.This configuration offers no parity, striping, or spanning of disk space across multiple disks, since the data is mirrored on all disks belonging to the array, and the array can only be as big as the smallest member disk.

Bei RAID Level 0 handelt es sich - wie die Null im Namen schon andeutet - um kein redundantes Speicherverfahren. Es dient lediglich zur Beschleunigung von Plattenzugriffen. Dazu fasst RAID 0 zwei oder mehr Festplatten zu einem logischen Laufwerk zusammen. 1.1 RAID介绍RAID是磁盘冗余阵列（redundant array of independent disks）简称磁盘阵列。RAID是一种把多块独立的物理磁盘按不同的raid级别组合起形成一个磁盘组，在逻辑上看是一块大的磁盘，可以提供比单个物理磁盘更大的存储容量或更高的存储性能，同时又能提供不同级别数据冗余备份的一种技术。 However, RAID 5 will not offer you the same speed as RAID 1 or the same capacity as RAID 0. It will take processing power to create the parity bits, and some storage space will be set aside for the redundancies.

RAID-1 has the same speed advantage as RAID-0 for reading, but no speed advantage for writing. You lose half your space, but if one of the drives fails, you still have all your data and can use the computer like normal. Raid 0/1 + Raid5? Har läst en massa trådar här om olika Raid konfigurationer men tycker fortfarande det känns förvirrande. Min tanke är att köra Raid 0 eller 1 på två stycken SATA diskar och använda dom för OS samt program/spel och sedan köra Raid 5 på tre eller flera 500 GB diskar. Raid 1+0(Raid10) 의 경우, 이미 Mirroring 후 Striping을 진행하므로 미러링으로 묶인 하드를 통하여 손실된 데이터만 복원이 가능.

On most situations you will be using one of the following four levels of RAIDs. RAID 0 RAID 1 RAID 5 RAID 10 (also known as RAID 1+0) This article explains the main difference between these raid levels along with an easy to understand diagram.

优点：性能上考虑的话，raid 0+1要更有优势一些，raid 0+1写入速度更快一些，读取速度和raid 1+0 一样， 缺点：一旦其中一块硬盘挂掉之后，一半的硬盘无法正常工作，如果2个条带上各坏一块，整个阵列将挂掉 De simpelste RAID-vormen, die alle RAID-controllers beheersen, zijn RAID 0 en RAID 1. De eerste zorgt voor betere prestaties, de andere voor veiliger opslag. Beide RAID-vormen zijn ook te combineren.

RAID 0 y RAID 1 distribuyen los datos de manera diferente. Con RAID 0 los datos se dividen por igual entre las unidades de disco duro del vector.

However, it has superior fault tolerance and rebuild performance. Minimum number of drives required: 4. Performance RAID 10 provides the high efficiency of RAID 0 and the safety of RAID 1. Just like in RAID 0, the read and write speeds will be incredibly fast, although the storage space will be cut in half, as is typical with a RAID 1 configuration.

I have an intel ICH8R/ICH9R SATA RAID controller. My PC came from Dell with 2 250GB hard drives configured for RAID 1(Mirroring). I have since bought an external harddrive for backup and now would rather have my drives configured for RAID 0(striping) for the extra hard drive space and performance. 2009-08-12 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.

Eftersom man på de flesta RAID controllers kan köra RAID 1 också,  LSI Cisco UCSC RAID SAS 2008-8i for C220 with RAID 0/1/10/5/50 Windows-drivrutiner kan hjälpa dig att fixa LSI Cisco UCSC RAID SAS 2008-8i for C220 with  RAID 0+1 — RAID-nivå. De olika kopplingarna kallas för RAID-nivåer. Vanligast är RAID 0, RAID 1 och RAID 5, men det finns  DeLock PCI kort 4x SATA 1.5 Gb/s RAID 0, 1, 0+1. AS-SX-109A. 349 kr.
