https://community.hpe.com/t5/disk/sas-disk-performance/m-p/4331174#M7142 I am comparing 2 disks that I am considering for use in RAID 10 arrays for exchange 2007. Performance per spindle, not capacity is the priority. Both are DP SAS Hot Plug, 3.5" ENT series 15K<BR />HP 450GB(454232-B21) and HP 300GB (416127-B21)<BR /><BR />In the same series, higher capacity drives are often higher performing, but it appears to me that these 450 might be a newer better performing series as well.<BR /><BR />has anyone benchmarked these, looking for max IOPS per spindle.<BR /> <BR />any experience is appreciated, Fri, 02 Jan 2009 19:26:36 GMT Mervin Cinq-Mars 2009-01-02T19:26:36Z https://community.hpe.com/t5/disk/sas-disk-performance/m-p/4331174#M7142 I am comparing 2 disks that I am considering for use in RAID 10 arrays for exchange 2007.
