举个例子:如果RAID1模式中有一块容量为20GB的硬盘和一块容量为30GB的硬盘,那么总体的RAID1的有效容量是20GB,从此那块30GB硬盘上剩下的10GB容量就会被浪费。 同时,如果两块硬盘的速度不同的话,那么速度较快的那块硬盘依然会停下来等待速度较慢的那块硬盘完成任务之后再进行下一步行动。 特点: 最少2 disks. ...
Raid 6:至少需要4块硬盘,2块磁盘冗余,硬盘的总数大于等于4即可。 Raid 10:至少需要4块硬盘,冗余一半的硬盘数量,但是硬盘的总数必须是大于或等于4的偶数(相当于每两块硬盘做一个Raid0,然后把各个Raid0做成一个Raid1)。 Raid 50:至少需要6块硬盘,磁盘的冗余相当于每三个硬盘做了一个Raid5,然后,每个Raid5又组...
RAID 1, with its full name known as "redundant array of independent disks," belongs to one of the RAID data storage technology modes. As a commonly used technology, RAID 1 aims to improve your devices' reliability, capability, and performance and help avoid various faults and errors. When y...
The best way to think about both raid10 and raid0+1 is you take the last digit, in the case of raid 10 that is stripping and apply it to the first digit mirroring which makes it a stripe of a set of mirrors. Conversely you have with raid 0+1 you have a mirror of striped disks...
1,563 Views I have an ICH7 family chipset with 82801GR/GH (at least, according to Windows Vista Home Premium 64bit Control Panel). I currently have two 500Gb SATA drives configured as RAID 1 and I am thinking about purchasing an additional 1Tb drive. Is it possible to have a 1000Gb ...
Hi I am expanding my array config with 2 extra disks to have more fault tolerance. I'm now at 16% but it has taken more then 15 hours now to reach this stage! Is

RAID 10 nests at least two RAID 1 sets within a RAID 0 configuration. This blends performance with potentially higher fault tolerance. Mirroring lends additional redundancy, which means that you can retain your data even if you lose up to half your disks — provided your mirrored copy does not...
RAID 0 consists of striping, but no mirroring or parity. RAID 1 consists of data mirroring, without parity or striping. 4. Can RAID 1 have more than 2 drives? Yes, a minimum of two disks is required for RAID 1 hardware implementations. With software RAID 1, instead of two physical disk...
RAID 1 (Mirroring):Provides data redundancy by creating an exact copy of data on two drives. Ideal for critical data that needs a backup. RAID 5 (Striping with Parity):Offers a balance of performance and redundancy, requiring at least three drives. Good for businesses that need both speed ...
