Just finished compiling this data.  Pricing is in CAD, with all sales/promotions included.  Products that were obviously a scam/fake, or had drastically out of line pricing (lower capacity costing more than the higher one, or just a huge leap from one tier to the next) have been excluded.

Additionally, here it is in $/GB format:

This confirms a few things that I've felt recently:

• Sweet spot for Flash Drives is around 256 GB
• Sweet spot for SSDs is around 1 TB
• SSDs are actually cheaper than flash drives if you need a sufficiently large capacity
