Write endurance on RAID 1 with two different size SSD

I have a RAID 1 with 2 120Gb SSD on a DL360 G9. One of the SSD have to be replace because it is complaining “SSD is approaching the maximum usage limit for writes (wear out) and should be replaced immediately”. I have a 200Gb SSD that will replace the old 120Gb SSD. I want to ask if the write endurance will increase on the 200Gb HDD considering that it will use only 120Gb of the capacity.

IMHO in theory yes, because it always has plenty of free space.

Hope this helps!

Thank you for reply.

Do I need to make any special setup to increase the endurance or just replace the old HDD with the new bigger one.

Re: Write endurance on RAID 1 with two different size SSD

If you replace a 120GB SSD with 200GB SSD in a RAID 1, only 120GB will be used.

The built-in controller of the SDD will ensure to use all the space and prevent hot-spots, however the usable space will be 120GB.


Hope this helps!
