Best NAS RAID Mode level?

Do you guys put your NAS in hibernate mode when your not using them? Just noticed my NAS lets me go from a RAID partition to a JBOD without losing data which is a nice feature.

Learned a lot on NAS drives already thanks guys

Wonder if the app, Western Digital Anti-Virus Essentials would block viruses and ransomware? @Caledon Ken.

Hi there

JBOD is actually quite a nice feature - especially if using different size (capacity) HDD's in those multi-bay external HDD enclosures. The computer software / hardware combination ensures that for ONE USB3 connection into the computer from the multi-bay device the data always gets read to / written from the correct HDD. I think if you don't need the speed of RAID 0 this is a good option as a failure on one HDD in the JBOD set won't mean a loss of data on the whole kybosh (depending though on how the files are spread across the HDD's of course).

Whatever system you use backing up to more than one set of media is absolutely important - although people say this ad nauseam on these forums there are still loads who never take backups and then complain that they've lost their data and can't get good help on recovering it.

As far as AV systems are concerned it's up to the relevant OS to handle that -- in general though Linux systems and proprietary NAS systems (which have their own OS in the box) are better protected against than Windows.

I find for things like Linux using a good firewall plus using the Routers firewall is often far more effective than typical Windows AV products - but again this depends on where you surf the web, what you download and a whole slew of other activities.

The other benefit of RAID1 is that if a disk goes faulty the service is maintained.
You just swap the disk out and it then rebuilds the new disk by itself.
With the capacity of disks these days you can normally get away with just a pair

Hi there

Very true but I don't think you actually understood the underlying question

Viz: OP asked What level of RAID to use

Most people got side tracked by getting too involved with technical answer rather than what the OP really wanted his system to do.

First thing is to ask what OP wanted. Now if He's already taking backups why would he sacrifice half of his HDD capacity to use RAID 1 -- the benefits are of course well known and if you have something that has to be online 24 / 7 --say a business payment system etc then RAID 1 makes sense.

Otherwise since you already have backups there's nothing wrong in using RAID 0 (speed) or JBOD (maximum capacity - especially for a load of HDD's of unequal capacity), On any failure OP can always re-build RAID 0 array / JBOD from the backups.

I think people need to understand what the OP wanted to do rather than the purely 100% technical "best answer".

I've experienced it more and more these days on client sites where a load of so called "consultancies" get involved -- seems more and more people - especially from some of those excruciatingly nameless off shored "consultancies" in SE Asia etc seem to write the code first and then expect the business to re-design the business processes around the spaghetti like sludge code that emanates from those sorts of places.

I'm sure any of you having worked on largish projects involving networking or large ERP systems like S.A.P etc know what I'm getting at here.
