Seven drives in a 6+1 RAID 5 configuration is a standard configuration in many storage environments. RAID 6 implementations require a minimum of four drives and have the storage capacity of N-2 drives because the equivalent capacity of two drives is exclusively dedicated to holding parity data. Also, you only need a minimum of three disks to implement RAID 5 as opposed to four drives of RAID 6. Disk failure.

With 2 parity blocks, it has the capability to compute data at a time of 2 disk failure. This is achieved through the dual parity block or drive in RAID 6 providing enhanced fault tolerance and enabling RAID operations to continue even if it encounters a failure. RAID 6 write operations are slower than RAID 5, as it has to write to an additional parity block. A RAID 6 configuration has a minimum of four drives.

In that case you almost certainly want to use RAID-6. With the rebuild time on an array with large drives you are at a much greater risk for a 2nd drive failure and therefore total array loss. With the low cost of drives there's almost no reason not to go with RAID-6 or RAID-Z2 or even Z3. RAID 6 requires a minimum of four disks and a maximum of 16 disks to be implemented. Usable capacity is always 2 less than the number of available disk drives in the RAID set.

Raid 6 is an extension of RAID 5 and uses two parity block for working which is distributed among all the disks in the RAID pool of RAID 6 and thus requires minimum 4 disks for its operation. With 2 parity blocks, it has the capability to compute data at a time of 2 disk failure. RAID 6 is like RAID 5, but the parity data are written to two drives. That means it requires at least 4 drives and can withstand 2 drives dying simultaneously.

RAID 6 requires a minimum of 4 drives and a maximum of 32 drives to be implemented. Usable capacity is always two less than the number of available drives in the RAID set. Usage: Similar to RAID 5, including file servers, general storage servers, backup servers, etc.

I have a MD1400 with (12) 10TB near-line drives on an H830. In the past using 3TB or 4TB drives on an H810 I would typically make MD1200 trays one virtual disk, RAID6, with a dedicated spare. But with 10TB drives that's 9x10TB or app. 90TB. When a drive fails in a 7 drive, 2 TB SATA disk RAID 5, you'll have 6 remaining 2 TB drives.
