Hi all, I´m starting to have tooo many files I don´t wanna lose (18 mpx raws weight a ton) without a proper backup and I don´t want to have to shoot myself in the case of a hard drive failure. It´s time for a real backup and these are my needings: - 2.5" external case - USB 3.0 - Powered by the USB cable itself - 512 GB – 1TB - Mechanical HD (SSD will be great, but my plan of becoming the master of the Universe and therefore rich is going surprisingly slow) Looks easy, but there are too many options in the market and I´d love to hear your opinions about cases and the drives itself because I´m a little lost. On the other hand, I have an Asus P5E-VM HDMI motherboard wich lacks USB 3.0 so I´m getting an PCI Xpress USB 3.0 card too. I´ve seen models from Conceptronic to Sharkoon costing from ten to twenty pounds and I don´t get what are the difference that justifies that extra cost (especially when the PCB layout seems to be exactly the same in that two examples). Thank you in advance. PSD: As usual, excuse me about my poor english.
