I just wanted to dispel the idea that $400 is actually overly expensive for what you are purchasing - becasue you are purchasing an extremely fast internal SSD for that $400 that is not really equivalent to a slow external SSD.

I suspect that only a few usage scenarios would actual benefit from the extra speed of Apple's internal SSDs on the M1 Max. So, do you need the speed or not? Only your usage can answer this question, but I thought I should mention it since your original post asked the question about the speed differential between an internal 1TB and internal 2TB SSDs. I have an external TB3 2TB SSD that today costs $870 on Amazon. I just wanted to dispel the idea that $400 is actually overly expensive for what you are purchasing - because you are purchasing an extremely fast internal SSD for that $400 that is not really equivalent to a slow external SSD. Do you need a fast internal 2TB SSD or can you get by with a fast internal 1TB and a slow external 2TB SSD? So the question again returns to your usage. Maybe I'm wrong on this, as I haven't done any research recently on this issue, so please correct me if I'm wrong. That is certainly true, but I would like to point out that for your $400 you can purchase a slow external 2TB SSD (roughly 1GB/s), but you'd be hard pressed I believe to find a fast (roughly 7GB/s) external 2TB SSD for $400. You also mention that $400 charge for going from internal 1TB to internal 2TB seems a bit large and that you can just purchase an external 2TB USB3 drive for the extra $400. These speed differences are minimal and for most usages will not make any difference in actual practice. Of course, the size required for the internal SSD totally depends upon the individual's usage scenario, as many have already pointed out.Īnd since you ask in your post #1 about the speed differences between 1TB and 2TB internal SSDs. ' Are there any spec / speed differences between the 1TB vs 2TB SSD storage options?'
