There isn't a sticky on this where people recommend the best drives out there. A bit confused why that is? Anywho...which of these is the fastest and makes the most sense without wasting money? - SSD? Does a USB 2.0 bottleneck exist making this a waste to invest in? - HDD? 7200 spin...10,000 spin...15,000 spin? Does it matter? (How are the load times?) - External SDXC card reader? class 10 card of course...(is there higher?) Thanks.
