MP 7,1 Apple OEM SSD -> same SSD transfer speed awfully slow

[LEOMODE]

Curious on 7,1 users. If you guys move files within Apple OEM SSD to the same Apple OEM SSD, is the data transfer painfully slow? I don't see the speed but I'm transferring about 90GB of data and it seems pretty slow (kind of like HDD transfer). In Task Manager it seems like Read Speed is about 70MB/s whilst write speed is about 600KB/s.

I'm curious if this is normal (meaning the speed itself is normal and I'm just perceiving it that way) or the speed will get faster only by transferring to another PCIe NVME SSD or something (because either from Apple SSD -> PCIE SSD or PCIE SSD -> Apple SSD write speed is much faster, like 3MB/s). I ordered 4TB so I don't have to worry about moving storages but if the internal transfer is this painfully slow I don't know if I should keep the 4TB!

Hello ~
Can you create signature with full setup specifications? I think you talked in another post about it but I can't remember and no time to recheck. Thanks if can.

I'm getting lighting fast copies, duplications, moves with huge 4K video files 25GB+.

Hey, I still have Mac Pro 5,1 and I haven't fully decided on whether if I want to keep 7,1 or not

But here it is:

12 core
32GB RAM
4TB SSD
single W5700X

I'm getting lighting fast copies, duplications, moves with huge 4K video files 25GB+.

Wow you're a mere one-up upgrade from my unit 12 -> 16 core, 4TB -> 8TB

Update: Ok maybe self-answering this, but it looks like this was bottlenecked by my other task which I was copying some files from other program. I would've thought it would still handle both jobs fast enough, but once that job is done my speed went back to normal.

It's filesize. Smaller = slow, gigantic = z00m!!1!@!

FWIW, different file-size benchmarks. Apple OEM SSDs (4TB in my case): Sonnet w/4 Samsung 2TB 970 EVO Plus (APFS RAID0):

This is the nature of all SSDs right now; Intel Optane has lowest latency / highest speed w smaller files.
