When the Caviar Green product line came out (1TB was when I first took notice), I was quite intrigued at the claimed power reduction. In electronics, heat is the main enemy of components. Usually every 10 degree C rise in temperature translates into a halving of component life. The Caviar brand looked like a way to get a much more reliable drive if the power reduction numbers actually panned out.
I took one of the drives in to work where I have fancy test gear at my disposal. In particular, I have some very good Tektronix current probes that let me measure DC and AC currents. I built a little cable that let me get to the +12V and +5V lines so that I could clamp my current probes around the wires to measure current consumption. I connected the two power leads to power supplies so that I could also vary the two voltages. In this fashion, I can accurately see and measure power consumption of the drive as I exercise the drive.Read more ›
They are a bit slower, adding about 33% to the seek time, but nothing noticeable to data reads. This only matters when reading lots of small files like during boot-up. I use an Intel SSD for my main drive and one of these for data. It is the best of both worlds.
I've found that most computers recognize these drives but must be told to mount them, format them, and assign them a drive letter. (This only needs to be done once.) This is a problem with large drives, not with these specifically. For true ease of setup, get a 1TB drive.
Other than the needless head parking, these are nice drives, especially for only $89.99 each (when I ordered them). I recommend these drives, but make sure you put wdidle3.exe on a bootable flash drive with DOS on it (Google for more information) and run "wdidle3 /D" to disable the head parking. If you would like to conserve some energy, let your OS spin the drive(s) down.
I use this new hard drive to store HDTV TV shows that I recorded live from Microsoft Windows Media Center and my AverMedia AverTV Hybrid Volar MAX USB TV Tuner stick. I also store my Apple iTunes library and my 1,050 CD collection using Apple Lossless encoding. Lastly, I keep a copy of my most critical data and software applications repository on the drive as well.
There have been no problems whatsoever with the hard drive or the hard drive docking station through USB 2.0 or eSATA connection. The Western Digital Caviar Green SATA hard drive and Thermaltake BlacX eSATA USB Docking Station are excellent choices that provide for an unlimited amount of storage capacity at a low cost. I intend on purchasing more of the same hard drives in the near future as my storage needs continue to grow.
I contacted both Western Digital and Thermaltake technical support within the United States to inquire about more information. Thermaltake requires that their BlacX hard drive dock utilize the eSATA connection exclusively with Western Digital hard drives that require the newer Advanced Format 4k hard drive sectors especially if the maximum storage capacity exceeds 1.00 TB.Read more ›
