Thank you for contacting us regarding the questions that you have about Raid 0 with different drives models; it will be more than a pleasure to help you out with this.
As we both know, RAID 0 is intended to boost or speed up the performance of your machine and provides no redundancy on the data that will be stored on the devices. Creating an array with 2 different drives but with the same capacity might not sound like a bad idea, and as matter of fact it is possible.
However if we go deeper into the devices specs you will see that:
950 Pro will work Up to 2,500MB/s sequential read and 1,500MB/s write
960 Pro will work Up to 3,500MB/s sequential read and 2.100MB/s write
The issue resides on the speed differences between both devices. If one disk is faster than the other, the speed is limited by the slower disk, so even if you double the performance of the slower disk by creating the array, the system failure rate will be effectively doubled as well, because the system will be more disposed to data corruption.
Having no redundancy whatsoever, will not be recommended on a system that could fail at any moment, since all data could be destroyed (unless you have a copy or a back up of course)
At the end of the day the decision will be yours, and even if it is possible, we do not recommend to create a RAID 0 array if you don’t have the exact same model of drives.
Hope this helps
