I have the earlier generation of the 2TB WD RE4 drive in one of my systems.
With Bonwick's diskqual script I saw an average of 119 MB/s across 14 drives.

drive can deliver 150MB/s on sequential access.

2009-09-01 Thread Richard Elling 

FYI,
Western Digital shipping high-speed 2TB hard drive
http://news.cnet.com/8301-17938_105-10322886-1.html?tag=newsEditorsPicksArea.0

I'm not sure how many people think 7,200 rpm is "high speed"
but, hey, it is better than 5,900 rpm :-)
