Hi, I will buy the new imac as soon as it comes out. I am planning to develop an application that would write data to the disk around 100MB every day (possibly more but for now I would think the upper limit is 1GB) and then transfer to an external storage. I heard warnings that SSDs have shorter life span compared to HDDs especially if multiple writes are done on the disk, but I haven't seen anywhere a quantitative comparison. The speed of bringing the applications up is not relevant except when it comes to my personal use and comfort. Can anyone tell me at what level are too many writes too many for a SSD, and what's your opinion, which one is better for me?
