Is it possible? Of course, but with a RAID0, you will only use the same size on the HDD as is the SSD, which will usually be smaller.

Will it provide good performance? Obviously not, except in edge cases where you read/write only from a fast stripe on the SSD. The slow stripes will severely impact the performance of the whole array. On average, you might end up with a performance boost, but it will be relatively small, depending on your specific workload.

That being said, there are a number of approaches you can take to actually improve the performance with this set:

  • i have installed the os on a ssd but i have remain two drives, one is hdd and the other is ssd. so what would be better : 1- use only hdd. 2- use hdd and ssd (raid 0) ? Mar 13, 2016 at 11:25
  • Use SSD and HDD separately is the best option. Mar 13, 2016 at 13:49
