2018 MacBook Pro 15" 512gb ssd vs 1tb ssd should be the same performance?

[IdentityCrisis]

Why do you keep ignoring that everything below 2TB performs slower for each size?

and yes apple did upgrade chips. from super neat Samsung chips to coil-whining Toshiba chips.

I wasn't ignoring. I was replying to someone with a 2tb speed test on a 2016. You need to read better. I have no noises from my MBP or any whine.

However, my Dell XPS does.

Well, you selectively avoid any posts that prove that 512GB SSDs are slower than comparable nVME drives.

Also, the speed bump from 2016/17 to 2018 is because of the T2 chip handling the striping.

THANK YOU. 100 thumbs up.

I posted that a 2018 512gb just like someone else above did perform 2600 writes vs what you continued to post.

so one in one youtube video performed 2600mb/s writes, while everybody else on these forums gets 1,9gb/s and based on that ONE result that nobody can replicate you concluded that all 2018 apple 512GB SSD drives perform at 2,6gb/s.

a result that might be due to outdated blackmagic tester that exploits APFS copy-on-write.

Nope, 1TB smokes the 512GB. It's one reason I went with a middle of the road config'd 2018 MBP 15" i7/1TB/16/Vega20. Like a race car (which I do drag race and build motors), it's all about selecting the right components to maximize performance and maintain lower temps, glta

That’s what I did in September too. Went with 1 TB. At first I thought I wouldn’t need that much space but I am over 50% used already.

Yeah, from me just installing Parallels, one VM on it, Office, Chrome, Firefox, syncing my photos with my phone, I am already at 600gb used on my 2tb. Now that doesn't include my bootcamp I gave 300gb too. 512gb is hard for anyone these days to live with honestly. Photos are getting larger due to the megapixel size, same with videos 4k, 8k, etc. One game was 30gb I downloaded in my bootcamp too.

I am also questioning 512 vs 1TB options, allow me to ask about how software such as Photoshop or Premier deals with scratch disk? (32GB ram) I don't plan to keep any files on the laptop's SSD everything will be stored on an external drive, but let's say I am working on a very big photoshop file does photoshop still need extra room for it's scratch disk or is that a thing of the past?

You can get NVMe/tb3 enclosure + samsung evo 970 1TB for 50% less money than the 1TB option and it will be just as fast as the internal.

I've posted this before - I don't have a 1TB model to test with, but here's a 16/17/18 with 512/512/256 drives

Way better than the 600-700MB/s I got from my 2013 MacBook Pro 256GB!!

Some good examples of how well an external enclosure works with SSDs.

Thanks, I hadn't expected the read speeds to be the same. Shows what I know!

It's no Samsung 970 Evo or Pro, but it's as fast as 99.9% of users need.
