WebYou must have two Hard Drives of equal size and capacity. You must have decided if you want to use RAID 0or RAID 1. We recommend RAID 1. RAID 0 Striped Disk Arraywith no Fault Tolerance - Provides data striping - spreading out blocks of each file across multiple disks, but no redundancy. WebOct 26, 2024 · RAID 6 has dual parity and can survive two concurrent disk failures. When third disk fails, the array is gone, and you'd need to restore the data from the backups. – Esa Jokinen Oct 26, 2024 at 5:23 4 As nearly everyone has already pointed out, a RAID6 can withstand only two drive failures. Are the drives actually dead though?

RAID 6 extends RAID 5 by adding another parity block; thus, it uses block-level striping with two parity blocks distributed across all member disks. As in RAID 5, there are many layouts of RAID 6 disk arrays depending upon the direction the data blocks are written, the location of the parity blocks with respect to the data blocks and whether or not the first data block of a subsequ… WebMar 20, 2024 · RAID 6.
