Surprisingly fast! 04/14/2014
Purchased 8 of these as a secondary tablespace array for a postgres database server. (The primary being 8 Dell enterprise SSDs) Installed on a Dell R720 with a PERC H710 card, bonnie++ reports 917MB/s seq writes, 1207MB/s reads! That's actually slower than my SSD array's sequencial rate of 843MB/s write, 979MB/s read. But as expected, the random seek latency is about 38ms with these drives, compared to 10ms with SSDs. Also, WD warranty is awesome, I always buy WD for my servers.
My observed seek latency of 38ms is significantly slower than I expected. It's also very difficult to find the average seek time of these drives in WD's official specs. So far I only found a mention of 3.6ms on a UK website, but I'm not sure I believe that. (See other thoughts)
My numbers could be due to many factors, like RAID hardware, stripe size, partition alignment, etc, etc. Take it with a grain of salt. Running queries against large 12GB tables on this array still perform faster than my SSD array, so that says something. (I'm keeping my indexes on SSD still though) Also a heads up, if you stuff these in a Dell server the OSMA going to complain that they're not official Dell drives. They'll be in "warning" status indefinitely.
