Raid 6 vs Raid 10: What UK businesses need to know before they Switch

Should UK IT professionals keep using Raid 6 or is it better to switch to Raid 10? Which version is less likely to fail? Is it better to use Raid 6 because it has dual parity or should companies opt to keep using Raid 10 because it can be mirrored and provides plenty of data storage? Before companies may a decision on which Raid system they will use, here are the facts about Raid 6 and Raid 10.

• Raid 6 offers greater data storage capacity. Raid 10 mirrors data and this requires that a Raid 10 system use additional data storage and also double the amount of data written to a hard drive. By contrast, a Raid 6 array uses 50 percent of the data disk space. The storage space also can increase if more disk drives are added.
• Raid 6 does require more processing power because it makes two calculations per one write operation. Could this also mean that you may need Mac hard drive recovery less with this type of Raid?
• Raid 6 can always protect against two driver fails simultaneously. Did you know that Raid 10 may not be able provide such protection and may cause a business to need data recovery from an external hard drive? External hard disk drives can fail causing the need for external hard disk recovery. Raid 10 may not always be able to protect if two drives fail, depending on where the failure is. If a Raid 10 system fails on the same drives, using the same mirrors within the rebuilt window, Raid 10 may not be the best option,
• Raid 10 has faster rebuild times. It only has to copy from a surviving mirror in order to rebuild a drive. Did you know it can take roughly 30 minutes with a Raid 10 system, but it can take significantly longer with Raid 6 because it must use parity calculations? Since Raid 6 takes longer to rebuild, it may not be the best Raid solution to use if external hard disk recovery is needed or Mac hard disk recovery is needed. Did you know that data recovery from an external hard drive can take more than 12 hours with a larger size Raid array?
