The WD Purple is a surveillance drive with low power consumption and a design that's optimized for 24x7 operation. There is actually little beyond marketing that separates the Purple from the Red and Green drives. They all share almost identical hardware. The thing that does differentiate the Purple drives is their firmware which supports AllFrame, a surveillance specific feature. Allframe handles the cache in a way that is optimized for video streams. The AllFrame technology however is only enabled when used in conjunction with a supported host controller, most of which are only found in dedicated NVR (Network Video Recording) devices. As a result there is no benefit in using this drive in a HTPC to record video streams, because the surveillance specific functions won't be enabled. In terms of effective speed the Purple lags the new Red and Green drives by around 26%. [Oct '14 HDrivePro]

This is the most recent version (2013 FZEX) of Western Digital's best performing consumer storage drive, its predecessor was the WD1002FAEX which is now four years old. With average sequential read/write speeds of 150 MB/s this version outperforms its predecessor by a whopping 50%. Small file random 4K speeds have remained broadly unchanged with average read/write rates of 0.9/2.19 MB/s. Overall the 2013 WD Black has a very good performance profile and it also represents reasonable value for money, at least in the 1TB category. There are some good alternatives to the 2013 Black including the 2012 Blue. Looking at the 2013 Black vs 2012 Blue shows that both drives have similar performance. Power consumption (6.8/6.1 Watts active/idle) and noise levels (29.5 dBA) are also identical making it a tough call between the two. There is however, as always, better value amongst the larger capacities. [Feb '14 HDrivePro]
