I have a VSP with microcode 70-06-13. I have an HDT pools with flash drives 300gb sas 10k rpm drives and some 2TB 7200 rpm drives.

I was told in the past that if i were to add 900gb sas 10k rpm drives they would be treated as 300 GB drives, so 600gb on each drive would just be idle.

 

I ask as  want to kick this pool up a bit but removing some 2TB dirves and replacing them with 10k rpm dirves. We won't be buying nay 300gb drives so I only have 900 gb as an option. If the hdt is going to treat the 900gb as 300 then I'd need to do some more moving around so I clear all the 300's out of the pool and backfill with 900's - trying to same myself some work.
