|---|---|---|
| 250 | 6 hours, 56 minutes | 1 month, 2 weeks |
| 500 | 13 hours, 53 minutes | 1 month, 2 weeks |

How does RAID 6 rebuild work?
The RAID controller takes the fresh drive and begins running its parity checks on the other drives. Using the parity data, the controller turns the new drive into an exact duplicate of the old one. This process is referred to as “rebuilding” the RAID array.
How many drives can I lose in RAID 6?
two disk drives
In RAID 6, two disk drives can fail without total data loss occurring. This means better security than RAID 5, but it also means even slower write speeds since one additional checksum must be created.
Is RAID 6 obsolete?
By 2019 RAID 6 will be no more reliable than RAID 5 is today. The Storage Bits take For enterprise users this conclusion is a Big Deal. While triple parity will solve the protection problem, there are significant trade-offs.
How long does it take to recover data from RAID 6?
The recovery process will take about 5 to 10 minutes for the smallest arrays. But if your RAID 6 array includes a significant number of disks, the time for recovery can be much, much longer. RAID 6’s only disadvantage is not related to data recovery.
Why is my RAID 6 drive not working?
The most common reason for RAID 6 failure is having some read errors on the disk drive. The most common mistake found on the SATA drive is URE or unrecoverable read error. It means that every two hundred million sectors, the disk will not be able to read one of them.
What causes data loss in RAID 6 arrays?
In addition to wear and tear, mishandling the device and physical damage are some of the main reasons for data loss in RAID arrays. RAID 6 arrays are capable of handling 2 drive failures without data loss but the failure of more than 2 drives will result in data loss.
