Hi al Does anyone here that knows if the new 7K3000 drives from Hitachi uses 4k sectors or not? The docs say "Sector size (variable, Bytes/sector): 512", but since it''s variable, any idea what it might be? I''m planning to replace 7x3+1 drives on this system to try to get some free space on some full VDEVs. If the drives are in fact 4k sector drives, will it be possible to remedy the performance penalty now that we have already used about 99% of the original drives?

I''m planning to[...] This PDF data sheet for SATA says 512, without the word "variable": http://tinyurl.com/4b6qgtc http://www.hitachigst.com/tech/techlib.nsf/techdocs/EC6D440C3F64DBCC8825782300026498/$file/US7K3000_ds.pdf Of course they could mean what''s reported to the OS (the SAS models say "512 / 520 / 528"). I''d e-mail or call Hitachi and ask them directly (the contact info is in the PDF).
