With that said, you will get much higher write speeds with RAID 50. Difference Between RAID 5 vs RAID 6. RAID is expanded as a Redundant Array of the independent disk. It is a storage virtualization method that merges multiple physical components into a single logical unit for performance improvement and data redundancy.

Raid 6 vs raid 5

So, while RAID 5 would be slow in actual writing, it will be hidden with a good raid controller - where the write occurs in memory from the perspective of the user/application. RAID 5 should never exist with a hot spare (warm spare.) RAID 6 is always a better use of the same drive count. http://www.smbitjournal.com/2012/07/hot-spare-or-a-hot-mess/ There is no space/capacity advantage or cost advantage to the RAID 5 solution (but some small performance advantage) but it does a ton for mitigating things like URE risk. While a RAID-5 array contains one additional drive, over and above those required to store the data, a RAID-6 array contains two additional drives. The capacity of an array consisting of N drives with minimum capacity C is thus given by the formula (N - 2) * C. RAID 5 vs RAID 6 - YouTube.

Typically, one of these parity functions is the same as in RAID 5 (XOR function), while the second is more complex. 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. Read speed is as fast as RAID 5, but write speed is slower than RAID 5 due to the additional parity data that have to be calculated.

Oct 4, 2019 Synology Hybrid RAID or SHR, has been around for quite a while now, A little slower than traditional RAID but equal speed to RAID 5 and 6

Como mencionado, apesar do RAID 6 ser mais lento, a diferença de performance é imperceptível quando o servidor ou sistema de armazenamento é novo. Porém vale lembrar que hard disks SATA são menos confiáveis que as unidades SAS ou memórias SSD, por isso ambientes que precisam de segurança adicional contra falhas precisam do RAID 6.

The most common RAID configurations are RAID 0 (striping, where data is split into blocks stored across Jun 28, 2017 Most of these RAID5 risks can be mitigated with RAID6. The rebuild failure rate with 600GB 7D+2P RAID6 Rank is 0.0000861% (as opposed to Oct 4, 2019 Synology Hybrid RAID or SHR, has been around for quite a while now, A little slower than traditional RAID but equal speed to RAID 5 and 6 Feb 26, 2016 RAID 5 can protect against a single drive failure, whereas RAID 6 can protect against two drive failures. RAID 5 and RAID 6 are otherwise nearly Jun 13, 2018 Raid 5 will have the lowest writes but put your data at risk if one device fails.

RAID 6 works based on both the parity methods and stripping methods in contrast to RAID 5 which uses dual independent parity functions that are printed to

From the above example both RAID 5 with Hot Spare and RAID 6 have same capacity, but offer different level of protection. In case of failure of RAID 5 array with Hot Spare, the Hot Spare is activated and the rebuild process start immediately.
