Hi

I'm always reading that you should not use SSDs in raid0 because of data loss.

Is this because raid0 has no redundancy or is it because using raid0 usually makes drives fail suddenly?

Thanks in advance.

It is because of zero redundancy. RAID 0 does not increase failure rate of drives though. Considering SSD failure rate is fairly low, I don't think RAID 0 SSDs is something to be afraid of, though of course critical data shouldn't be kept on it. The only thing is there's really no benefit to RAID 0 SSDs, it just increases boot time since the RAID controller has to initialize.

due to redundancy.

 

In raid 0 if 1 drive fails ..that's it.

 

SSD's have a lower complete failure rate than HDD's, but higher Data loss and incorrectable errors over time.

 

The more SSD's in a raid0 the higher the chances of loosing data or even seeing failure of the entire raid due to data loss, requiring format and recreation.

 

BUT, its nothing to be really worried about so long as the data is not irreplaceable. Also RAID 0 SSD's doesn't make much sense as u would likely never notice the difference unless ur constantly doing file transfers.

RAID was designed for data redundancy. RAID 0 isn't a RAID but people still call it however it has NO data redundancy at all. More drives in a RAID0 = more likely to go wrong.

doesn't it double your drive space then?
