Samsung SSD T7 and Mac Studio m2 Max not 100% compatible.
When I reformatted my Samsung SSD T7 4TB in my Mac Studio M2 Max/Ventura with disk utility the read speed dropped dramatically from over 700MB/s to under 300MB/s.
I tried reformatting it in my previous computer (imac 5k 2019 3.6 Ghz 8-core Intel core i9) which thankfully I still have but the error remained.
After some searching, I found a Samsung software that could restore the SSD T7.
(SamsungPortableSSD_1.0.app) But it must be done in my imac/Monteray. If I understood correctly, it cannot be run under Ventura
After restoring the SSD T7 with the software, I did a new format in the imac/Monterey and then the speeds increased. But speed differs..
See photo higher Speeds from imac/Monterey:
See photo lower speeds from Mac Studio m2 Max/Ventura:
I also found out that speed increase if formatting with Mac OS Extended (Journaled) not APFS.
So what is going on new Mac Studio M2 Max can’t handle the SSD:s ?

Hey Jan,
Completely left-field, but I am wondering whether Apple wants you to connect the drive with an Apple Thunderbolt 4 cable?
They have been known to make it “difficult” for 3rd-party cables to work with their kit.

The performance of external USB drives on M1/M2 Macs has been posted about before.
There is a reduction in R/W speeds for USB drives on M1/M2 Macs compared to Intel Macs. It’s to do with USB 3.1 Gen 2 compatibility in the M1/M2 Macs. This issue was more pronounced in older M1 based MacBooks but has improved somewhat with newer M2 Max and M2 Ultra Macs. But still not as fast as the same drive on an Intel Mac.
On solution that some propose is to use a Thunderbolt hub between the Mac and the USB drives. There are some YouTube videos demonstrating this. But the improvement is marginal to substantial depending on the drive and cable. Its too unpredictable.
I now use only Thunderbolt external drives with my M1/M2 MacBook Pros and Mac Studios. They cost a bit more but they work well.
