In terms of specs, price and age the Video SV35.6 appears to be identical to its 2TB Barracuda 7200.14 sibling. We have only seen nine user samples for the SV35.6 so far so we don't have enough data to formulate a strong opinion as yet but based on the samples we have seen, this drive appears to underperform the barracuda. Peak sequential speeds are similar but random 4k speeds lag by around 15%. It's possible that these are just statistical discrepancies that will iron themselves out as we see more samples but in the mean time we would recommend the barracuda 7200.14 over this drive. [Jan '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]
