Bear in mind that the total capacity a RAID 1 would offer is directly proportional to the total capacity of the smallest hard drive you use. So, it is best to use hard drives of the same storage capacity. You need a minimum of two drives, but you can use up to six (6) or more ...
Disk mirroring ensures that there is at least one exact copy of the data at any given time in case ofdrive failureor other significant event. For this reason, a RAID 1 array requires a minimum of two physical drives, which is the typical configuration. It's possible to set up an array...
RAID 10 stripes the blocks of data to each RAID 1 array. Each RAID 1 array then duplicates its data to its other drive. Minimum number of drives is four. Level 50: RAID level 50 employs the features of levels 5 and 0. RAID 50 includes both parity and disk striping across multiple ...
RAID-1:可用于一个固态盘的容量足够,并且需要更高的数据可用性和/或双倍读取性能时使用。 RAID-0:当潜在的数据丢失并不严重时,可与工作站类型的应用程序一起使用。提供最高的性能和最高的性价比。 RAID-6:不太可能与固态盘一起使用。 主要设计用于重建时间较长的高容量硬盘。
yes, both raid 5 and raid 6 use distributed parity to provide redundancy. raid 5 requires a minimum of three drives and can tolerate one drive failure, while raid 6 needs at least four drives and can withstand two drive failures. can you explain raid 10 in more detail? raid 10 is a ...
