I'm looking at getting one of these drives and tossing up between the 2tb or 3tb.
What I've noticed is there is a very slight price difference between the two and then a massive one between the 3tb and 4tb
Can anyone comment as to why that would be and provide any personal experience with them?
3 TB have historically been the sweet spot for cost per byte. This happens because higher densities in the same amount of physical space costs more to manufacture, and they charge a premium on higher capacity drives coz its usually the enthusiasts that go for them and they can afford it. But as even higher capacity drives continue to hit the market and saturate the commercial market, the cost per byte of the 4tb should, in theory, continue to drop to around or just above the 3tb drives. However there are other market forces at play as well that may be keeping it high such as exchange rate, supply/demand, etc.
The general consensus on brands seem to be that WD has a slight edge over Seagate in terms of reliability, so if you can get a wd for the same price get that instead. But always be aware that mechanical hard drives can die at any moment. Their warranties are usually pretty good and easy to action, but that doesnt help you if you lose all your precious photos on it so ALWAYS BACK UP.
