Raid Helps

[TheAmazingCookieFromSquare]

I have two Crucial BX100 SSD in 120GB 

 

Which Raid should i use

[vorticalbox]

raid 0 for speed

raid 1 for redundancy

I want da speed but wont i loose all the data like isint raid 0 unsafe

[vorticalbox]

I got it wrong its the other way.

 

raid 0 will stripe data one part to each drive, this increases speed as you're writing half to each drive rather than all of it to one. This allows for 100% use of capacity

 

raid 1 will copy all the data on one drive to the other the halfs your capacity but allows for one drive to fail and your data still be available.

Will raid 1 give me da speed?

no you'll want raid 0 for that.

But raid 0 will cause data failure

No. RAID 1 is just mirroring. The speed will be more or less the same as a single drive. 

 

I would personally not recommend RAID with such low capacity drives, it's just not worth it.

It doesn't cause data failure or loss, it just makes it more likely, as you have multiple drives to fail rather than one. The real world speed increase from RAID 0 is not that large, either.

it doesn't really make it more likely just a lot more destructive if it does.

 

I have a ssd and then two 500gb in raid 1 which are backed up to my nas.

 

with this set up I can lose 2 drives and still recover all my data, does mean I only have 500 on my pc rather than 1tb

RAID 0 does make loss of data more likely (assuming there's no backup) as you're adding more points of failure with each additional drive. Indeed, it also makes it more destructive as it's much more simple to retrieve data from a single dead drive than from striped data on multiple drives. 

 

I run a RAID 0 setup myself, but it's for somewhat stupid reasons (do as I say, not as I do xD). Everything's backed up to an external drive and important data is backed up to the cloud. If you ask me, RAID is mostly a waste of time outside of high capacity RAID 5 or 6. A good backup is normally much more cost effective than RAID. That being said, RAID 1 can make sense if you don't need the space and essentially have a spare drive.

If made well, raid 1 can have read speeds the same as raid 0(read in stripes)
