Is raid 1 technology secure


Mar 28, 2012
Looking for a network backup/storage drive that is secure to internet threats (intrusion, virus..etc.) Having difficulty finding a quality product.
Any recommendations?


Your topic and the text in your question do not work together. A drive is going to be as secure from virus/intrusion etc as the OS it's being hosted by is. Raid 1 has nothing to do with how secure a drive is from something like a virus, it's basically duplicating data to 2 drives when you save something in case one of the drive dies you should still be able to access it on the other one.

RAID1, as tomatthe said, is only a secure way to keep file duplicates around in case one of the two drives dies. All it does is allow you access to the FILE when in reality it's on both DRIVES but you only see one physical drive in Windows. Handy, mainly for servers and high-end workstations where data integrity is key (power outages, longer-lasting systems, etc). For the normal end-user it won't really benefit you much.

In a nutshell, both copies of the file would get infected anyway, should you get some malware of some kind, so absolutely not: RAID1 is not helpful against malware.

The only way to totally secure your data from Internet threats is to make sure it does not reside on a machine that is connected to the Internet. You should look at using something with a small attack surface, like a separate machine running FreeNAS. That will help guard against malware/viruses that find their way into your local network. And yes, RAID only helps prevent data loss due to drive failures. RAID 1, 5, 6, 10, etc... all use multiple drives in an array and the array can suffer the loss of 1 drive without data loss. 2 drives with RAID 10 and 5 or 6 if using a hot spare.
