dunno if HW controllers can support this. Different RAID levels represent different configurations aimed at providing different balances between performance optimization and data protection. It is an older system.How i can check if it is possible? Reply Laurens says: January 12, 2015 at 11:07 pm I cannot give you a short and relevant description of how to do this, especially not without any knowledge of your setup. this contact form
Fault tolerance lessens interruptions in productivity, and it also decreases the chance of data loss. Read more about Ramesh Natarajan and the blog. If any drive in a RAID 0 configuration fails, you could lose all your data.

If I want to add a 3rd drive to the RAID can this be done easily, or would it mean having to rebuild and reload the array, or would it be I deceided to use it on case scenarios such as: if two active disks fail at the same time. With RAID 6, the RAID array will even survive that second failure. Raid 5 Calculator A mirrored 16 TB RAID 1 system gives you 8 TB of effective capacity, which means you'll run out of space again pretty soon.
The capacity of a RAID0 volume is the sum of the capacities of the disks in the set, the same as with a spanned volume.

This is because addition in any characteristic two finite field reduces to the XOR operation.

Raid 50 Because of the increased storage demands of consumers, home NAS devices also support RAID.

Best practice is to have three copies of your data: the original, a backup, and a backup of the backup, preferably offsite.If you have existing data that you want on the
Are the removable mirrored drives (CRU and G Tech) a good solution to this issue. If you go for a NAS box its software takes care of making those mirrored drives appear as one partition.

It requires at least 3 drives but can work with up to 16. Windows 7 Home allows JBOD and RAID 1 while Professional and Ultimate add RAID 0 mirroring. Raid Movie

The disks are synchronized by the controller to spin at the same angular orientation (they reach index at the same time[clarification needed]), so it generally cannot service multiple requests simultaneously. Is it a 6GB/s transfer speed or any other? All RAID levels except RAID 0 offer protection from a single drive failure. http://robotadv.com/raid-0/raid-0-offline-need-help.html A business will generally find it more urgent to keep data intact in case of hardware failure than, for example, a home user will.
