JBOD RAID question

[Heeter]

Hi all,

If I was to lose a drive in a 4 drive, JBOD RAID setup, would the other 3 drives still retain the data on them?

Or would the JBOD collapse entirely like a RAID0 and lose all data?


Thanks

One advantage JBOD has over RAID 0 is in the case of drive failure. Whereas in RAID 0, failure of a single drive will usually result in the loss of all data in the array, in a JBOD array only the data on the affected drive is lost, and the data on surviving drives will remain readable. However, JBOD does not carry the performance benefits which are associated with RAID 0.

Standard RAID levels - Wikipedia, the free encyclopedia

That answer your question?

No, you would lose all data. JBOD stands for "Just a Bunch Of Drives". With it you don't need to have the sizes equal, and it has no fault tolerance. Also, JBOD isn't really considered raid.

That answers it,

Thanks guys,

Just double checking.

BTW, thanks for the wikipedia links too.

This is a old topic. With SSD these days you don't really need to use RAID for performance..maybe for data protection

Huh?

Did you check which section I posted this thread on? Server section. This is a Server question, not a standalone computer question.

I posted this under three weeks ago. Old would be you answering this two years from now.......

What he meant was that with SSD being around, this is a old topic. Personally, I think that is bull ****; especially when people aren't going to shelling out 500.00 for a 20 gig ssd drive

Hey thanks Johnny. misread what he said then.

Also, your right about that.

Thanks

I just plain don't think anyone should bother with SSD's in the first place. The only place I've seen them be any use is in situations where you have a database server that needs insanely fast read/write times such as is the case with EvE Online or Facebook for instance. Then you are looking at SSD's that don't cost less than $10k US each.
