So the effective benefits is only if i have a SD or USB external drive, in this case is much easy to replace
But in my case i have a Dell Internal Dual SD Module with two SD Card 1 GB in RAID1.
At this point is better install Esxi on the 300GB SAS Local Drive because if it's fail is more simple for replace it then use a Dell interal SD Card if is fail i need to open the lateral chassis the replace the SD fail.
So definally yours tell me is better use a drive external and non internal but in this case i have no LOG for SMART and not redundacy.
I think in my case is better install on HDD or not?
