Extremely slow external SSD’s and HDD‘s on MacBook Pro 16 M1 Max

[mva68]

Ok switch to Windows 11 then for audio production, what a mess.

Same problem for me. Killed the speeds on my UHS-II SD cards on both M1 MPA and M1 MBPro16. Checked with Blackmagic Speed Disk and went from 180Mb/s write to 45Mb/s. Seriously Apple?

I worked on it all day; nothing helped. Only quick option appears to be downgrade to Monterey

and did you downgraded?.. wonder if that helps

Hey everyone. I had the same speed degradation issue with my Samsung T7 SSD on my iMac 14’’. Solution: restart the machine in Safe Mode. Hold the switch-on button until the splash screen, then hold shift and click on your main disc. Fun fact, I have both the new MacBook 16’’ and the iMac, but only the iMac was affected by this issue 🤷‍♂️

hello, boot system in safemode, holt shift and click on main disk.. and then what? thanks

I haven't tried it yet. Theoretically it should work but after hours and hours I can attack it today.

You should be able to do a Time Machine restore from the Safemode menu (If you did a backup from Monterey)

no time machine restore!
HERE IS THE SOLUTION:
just quit your mac - hold down power button till you see the two options and click on "macintosh hd" it will restart your mac and the issue is gone for me..

just plugged my hdd and raws 100mb raws and its previews is finally loading!!! try it guys

Temporary fix but it works for now.We shouldn't have to run our computers in SafeMode.

temporary? u think that if i restart my macbook the ext. hdd will be slow again?
i thought that it fixed it.. gonna try

omg yea, it is slow again...
and running our macbooks in safemode could hurt them or is it bad for them?

of course i should be working without safemode.. just asking

I don't know whats up. It worked on my M1 MBA but not on my new MBPro16. In fact, the TV app won't work at all on the MBPro now.

i had one hour call with apple support. we came up with three solutions:

1) when u make a new user - the problem is gone, so the first solution is to migrate data from old user to the new user

2) THE EASIEST solution is: go to settings - general - login items - and if you have app called "open" try to disable it and restart your mac - then try to plug in your hdd or ssd or sdcard if you see any difference (i tried this one)

3) when in that settings - click (i) info button near the "open" app and it will show a folder with it - backup it and then delete it - it just custom settings for some apps - could help too


in my case it worked - i can finally see previews of my raw files and its loading!
try it and let me know please

I tried creating a new user but it made no difference. I disabled the "Open" exe file from start up early on and it didn't have any effect. I did these things after I already spent 6 hours trying to figure out why iCloud was crashing and the settings menu would freeze. That was fixed when I completely removed my VPN app and emptied it from the Trash bin.

can you please tell me everything that you tried?

It would take me an hour to list everything I tried. This is what I've discovered. I spent over an hour on the phone with Apple on two occasions today; no help whatsoever. They're trying to blame Sandisk for the slower speeds after upgrading to Ventura 13.1. I've reinstalled Ventura from scratch and reinstalled my apps one at a time. That resolved the SSD issues but my SD card write speeds are still abysmal. I've tracked that down to file format. ExFat formatting is just REALLY slow on write speed. Read speeds aren't as fast as normal but I can live with 200Mb/s. Reformatting to MacOS Journaled bumps things back up to 220/250mb/s. However, my cameras only use exFAT so I'm SOL. Only other option is to downgrade back to Monterey and after 3 days of working on this I don't want to jump into it right now. I suppose I'll just ride it out and see if Apple comes up with a bug fix in the next upgrade.

My T7 SSD was acting curiously (saying a file didn't exist that I was trying to open) so I ran Blackmagic and noticed that my drive has halved in write speed as well. Not as low as the people have posted here but still down. It also took a minute or so to mount instead of being instant.

I recently updated to Ventura AND updated my T7 SSD to APFS from Mac OS Extended. I'm not sure if the APFS change is making it worse. Sounds like dropping back down to Monterey may be on the cards. Very annoying.

 

[Madonion]

I can agree that the read/write speed to a ex/fat or fat formatted usb stick is slow , I have only one formatted this way the rest are in apple format
like another poster I need one in windows compatible format as I use it on sneaker net to transfer files from fusion360 CAD/CAM "Gcode" to the windows based CNC controller in the workshop ( dare not have it networked incase traffic glitches the controller )

BTW I am using 13.2 beta one the studio max

anything new? i just tried my hdd on my friends macbook air M2 which has montery and thumbnails of my raw files loads instantly...
so there is a problem either with my macbook pro 14" 2021 or with Ventura itself

my folder with raws when i plug it into my mac looks like this.. halfly loaded and very slow and laggy when scrolling:

I downgraded back to Monterey 12.6.2 and everything is fine now. No problems whatsoever.

 

[dawepr]

can i ask you, did u try to reinstall the ventura or went straight for downgrade to monterey?

I reinstalled Ventura as a completely new install first but it made no difference. I ended up doing a fresh install of Monterey and reinstalling all my apps. It was actually quite easy on the M1 MacBook Pro.
