Western Digital recently (and silently) slipped a SATA 6Gb/sec model into their Caviar Black lineup.  We obtained a sample to evaluate how this drive stacks up against the other WD models.  We're also using it as an opportunity to evaluate performance across several controller types.  We'll be using our trusty ICH10R as well as a few new Marvell controllers sporting 6Gb/sec SATA.


For those curious, this new drive does not incorporate Advanced Format.  I suspect Western Digital will be leaving that feature to their lower spindle speed drive lines, since larger block sizes have a negative impact on smaller-than-2KB random writes - similar to what happens with a 2KB stripe size RAID.
