I've read that a larger solid state drive (SSD) can have faster read and write speeds. Is there a point at which there are no more gains as you get to the extremes?

For instance, would the 4TB option on the 2020 MacBook Pro be faster than the 2TB version (or is it only faster when you go from a 512MB SSD to a 1TB SSD)?

Is there any data for the 13.3" 2020 MacBook Pro?

I could be wrong, but all the Apple's internal SSD speed should be the same. I have 13" 2020 MBP APPLE SSD AP2048N 2TB, didn't realized any SSD speed difference from my old 13"

Thanks!

Maybe faster speeds were only seen from the larger sized SSD when they first came out. Maybe they are all optimized to be the same speed today. I was hoping for improved performance for the larger size SSD that I ordered.

read speed is about the same across the board, but write speed, the more ssd cell the faster, for example 256 would be faster than 128 due to more nand cell to write to at the same time, it determinants after 512gb i believe, at which the write speed begans to even out due to controller limitation. you should only be wary of write speed only if its under 512gb.

Are there any negative aspects of getting a large SSD (besides the high price)?

Basically that, the high price, especially the price Apple charging, mlc nand 512gb goes for less than 100 bucks but Apple wants 200 for going from 512 to 1tb, I guess that’s the Apple tax
Nand ssd are also subject to write degradation so the more storage the healthier the ssd can manage itself in the long run. Of course that only matters if you constantly write to it everyday for like many years.

Would the 4TB SSD use noticeably more power than the 2TB SSD or would it be negligible?

it will draw more power but its so small its unlikely for you to notice. you probably save more power by dialing down the screen brightness by couple nits. ofcourse if you can get a smaller ssd and just get a external drive, its much cheaper that route consider the price apple charge per tb.

I like to have everything with me in one small package (the Macbook Pro). :)

Me too. I've ordered the 2TB to give me plenty of room for my photo library to grow. Don't want to have to get out an external drive every time I want to access older pictures. Having said that, I'm fortunate to be able to get the 2TB.

I have the 8TB drive and so do all of my employees. It’s insanely fast, but howevermuch faster it is than the smaller size drives, you are not going to notice the difference other than through disk speed tests.

I would recommend still buying an external drive, just in case something happens to the mac. The new SSD's are nonrecoverable on Catalina with the t2 chip.

That's exactly what I did. I have two backups one is use an external 8TB drive for time machine. another one is use a caldigit tuff nano 1TB SSD 10Gbs to backup my most important files from time to time. Fast and clean.

So, do Time Machine back-ups no longer work in Catalina? I’m still using the previous version of Mac OS X on my current computer.

Time Machine works fine. The issues is if you have not backup something or modified something before you last backed it up, the current version is only on the MPB's drive. And that drive is encrypted. So if your system dies, your data becomes inaccessible, perhaps forever. That is why with new MBPs data backups off your system, and if the data is critical off your premise, are more important than ever.

Time Machine still works, but it is slow. I like Carbon Copy Cloner. It takes about 20-25 minutes to fully back up 300GB, and then updates are typically 5-10 minutes. What’s nice is that it does have a feature broadly similar to Time Machine in that it keeps files from previous backups until you run out of space. I have an external Thunderbolt 3 enclosure (Shell Thunder, which is $140 on Amazon) with an m2 NVME SSD (2TB is about $240-280 depending on if you get a QLC or TLC drive).

Damn they cost that much now? I bought my p660 2tb for 164 last year
