I will add a new HDD to my computer (identical to the old HDD).

I'm wondering if it's a good idea to do a raid 0 vs using the two drive separately.

How much it impact the latency and the performance.

Specially for small random read and write.

RAID0 should either do nothing or decrease the impact of latency and increase performance depending on the configuration and load. I would expect it would have a positive effect for small random read and write.

The disadvantage of RAID0 is that if you have a drive failure, all your information is likely to go, whereas if you use the 2 drives independently you will still have the data from the unaffected drive.

  • I do regular backup so I'm more interesting about not having to worry where i should put my data and get better performance. Is there some case when raid-0 is slower? – Fractale Jul 02 '18 at 06:34
  • Not really. Worst case would be no better then single disk performance depending on where the data is. – davidgo Jul 02 '18 at 08:32
