Can someone please confirm what it means to "initialize" a virtual drive on an LSI MegaRAID card?
I've read in some places that it's writing zeroes to all the drives (Fast Init only does it to the first/last 10 MB, Slow and Background Init do the entire drive space).
Assuming I'm correct, if I'm setting up a RAID 1 or RAID 10 with SSDs that I've just secure erased, wouldn't writing zeroes to the drives (A) be total overkill since the drives are already consistent and ( B) severely impact performance until GC has time to clean things up?
I've also heard that performance may be degraded if the RAID card isn't sure the drives are consistent. Is this true? If so, would running a consistency check shortly after setting up the virtual drive solve that?
Many thanks in advance!
