We are using SSD drives for storage, but while checking datastores its showing "non-ssd". We have not performed non-ssd to ssd change command while setup the ESXI host.
Now we are running 40+ vms in the host. If we using SSD and datastore showing "non-ssd" it will give any performance degrade / it will give only non-ssd io perform?
Please clarify this SSD - non-SSD
It will have a performance degradation. ESXi kernel will look at it as a non-SSD disk and perform accordingly. You need to mark the disks as SSD if you want a SSD level of performance.

Hi,
yeah, sorry, I am digging up, but : this question is still actual and people seeing this could base their knowledge on this last answer.
"It will have a performance degradation. ESXi kernel will look at it as a non-SSD disk and perform accordingly. You need to mark the disks as SSD if you want a SSD level of performance."
Well I am surprised. Your answer is based on what please ?
What kernel might do to lower the SSD perf ?
I think it is important for vSAN, for ESX to know which disk is SSD or not, but not for any array based storage.
Also I am asking this to SupreetK, of course every experts thoughts will be welcome.
