Will RAIDing SSD  make them last longer as te load is 0.5 on 1 SSD and 0.5 on the other SSD?

It can actually put more stress on the drive and SATA controllers (if you're not using a dedicated RAID card). It will reduce the amount of writes to each drive, so they may last longer in terms of write cycles. 

EDIT: Also, bear in mind the load isn't 50%, the data being written is 50%. The load is still 100% (theoretically), which is why RAID 0 makes transfers faster.

Hey there CRNoBOG

 

RAID generally puts more load on the controller itself and more stress on the drives, keeping them aligned and synchronized. 
In terms of pure writes, you are not very likely to reach that amount with regular usage as you are far more likely to encounter other problems or to simply upgrade that drive before actually reaching the write limits. 

On the other hand, RAID0 offers no redundancy at all and even though you'd be using two separate drives for the same data, and thus writing less data on each of them, you would be risking array problems and the need to reformat those drives in case something happens. 

I'd rather use a single SSD and keep the second one as a reserve or as a secondary for better data safety.
