Re: Can the new feature ES0S 775 GB 4k SSD drives be used in a 5887 EXP24S in P7-8205-E6C?

IBM Say the ES0S drives are Power8 only.

As for the difference instead of 512(520) byte 'sectors' (we know they 
are really not sectors on SSD) instead the new ones use 4K Blocks. In 
theory this will be better for performance most of the time because 
there are fewer I/Os done (1 to 8).  Practically it means that more disk 
storage can be addressed with the name number of blocks.

I seem to recall that IBM i moved from 512 to 4K (or was it 2K?) blocks 
back in the CISC to RISC days So logically this should be a smart move 
for IBM i to move to 4K block storage.
