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]

The 1TB Seagate Barracuda 2016 (ST1000DM010) has an impressive performance profile. With Sequential read/writes averaging 173 and 159 MBps respectively, the Barracuda can make short work of even moderately large backups. The small file (4K) performance profile is less impressive but still adequate with average read/writes coming in at 0.87 and 1.53 MBps respectively. For use as OS drives, rotational disks are quickly loosing market share to SSDs which offer orders of magnitude faster 4k read/write speeds. On the other hand cheap TLC based SSDs often have slower sustained write speeds than their rotational counterparts. Reasonably good overall performance can be achieved by using a TLC SSD to host the OS and a larger rotational drive such as the Barracuda for backups and media files. Larger capacity variants of this drive offer both better performance and better value for money. [Feb '17 HDrivePro]
