A good time for SSD buying is subjective. For the Anandtech forum community, it is a great time to buy. For others, not a absolute truth. For cheapskates like me who need storage above all, SSDs are still too expensive. Many non-tech saavy people don't even know what SSDs are.
All I am saying is to not confuse or mix your tolerable price/performance (capacity) curves with those of other people. What seems like a good deal to you may be another person's dealbreaker and vice versa.
I didn't say to just wait and wait and wait for the next big thing around the corner. But establish your own price and performance/capacity tolerances and buy when those are met. OP, I hope you are still paying attention as I have repeated this point many times now.
zCypher, I am using performance as a term to indicate capabilities of the SSD. Whether that is read/write speed, NAND lifespan, storage capacity is up to the consumer to decide and judge on. For every product in the world, there are two factors: Price and Performance.
