How a Lenovo RAID Controller will present Native 4k drives to ESXI 5.5u3?

Hello all, I am wondering if it is possible to get around this issue...

I had asked a similar question to this before and Andrew Hancock had gave me a good answer.  This question is not a double post, but more related to elaboration.  How does a RAID controller present native 4k drives to ESXI as 512?  Does it do this as 512e which ESXI 5.5 also doesn't support, or some other method?  Is there a performance hit to this?  Does anyone know if this specific Lenovo RAID controller can handle presenting 4k drives to esxi as 512?

LOL does my line of thinking even make sense?  We had bought a bunch of 1 TB drives, which we are going to RAID6 once we decide on a server, but I am wondering if we can send them back and get >2TB and get more capacity.

VMFS is formatted as blocks and sub-blocks, so there will be little performance hit.

I assume you are RAIDing disks, and not using these disks directly ?

Hi Andrew, yeah I would be raiding the disks and not using them directly.  We are thinking of RAID 6 using Lenovo's RAID controller.

so that depends, on what RAID block size you use when you create the array!

some vendors call this the stripe size.
