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

I’ve updated to 13.1 Beta 2 but need to do more tests today, for some drives it’s looking positive though

Having the same issue. My external HDD is practically useless on Ventura. This isn't much of a workaround until Apple sort this nonsense out, but if you need to access/copy files to or from an external HDD, then install Windows 10 or 11 and access the drive through Windows. It will load and copy files over at "normal" speeds. Just tested it now and it works well.

I've been feeling that the last few iterations of Mac OS and some Mac models have had issues with drives and drives speeds, including file integrity. I know the chipset powering the m1 has issues with certain chipsets on SSD's, NVME drives and enclosures. I had a MFN rip apart and replace an enclosure this year and they could only conclude it was the Mac. (the drive worked fine on Windows)
 
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 🤷‍♂️
 
So I wiped my M1 Mini and clean installed Monterey and USB speed tests ran on multiple drives as expected. Then installed Ventura update and the same drives went from 700-800MB/s to 500MB/s and under. It's definitely Ventura. And yes, I've tested 13 and 13.01, no difference.

I have a feeling this did occur in MONT and disappeared in .1 patch….

This message will be a little offtop, but I want to say my opinion. I think what Apple is now is just some parasites who use all the fame that was left from Steve Jobs. There is no any innovation, style or care anymore. And it’s so sad to see.

Each update they do worse and worse things. Even with things that you have to try hard to make it worse but they still manage to do it. Take a look at search bar on Mac. It was beautiful stylish slim line, just enough to type in it. I loved that search bar. Every time I opened it I got a pleasure for my eyes. In Ventura, they made a bulky search window that takes so much space of the screen and cringe me each time I open it. This tells me that who runs the company now has no idea what ideals and principles were in the company at Steve Job’s times.

The file system organization in Ventura starts to look more and more like Windows. And I, personally, find this so uncomfortable to use. They add extra actions to do things, now you have to make extra clicks to get what you need. This doesn’t look like Apple anymore.

The politics of the company now is “we will give you freedom and put everything on top for you find all you want yourself”. But this makes it a total mess and takes time and effort to get to the result, especially if people are not too tech. With Steve Jobs it was real care about people to not have to do anything extra and get results faster with no effort and this was so amazing. Now it’s just “spend your own time to do things” and popular saying DYOR will fit here perfectly. But Mac principles were exactly the opposite. When people spend money to buy something that should make their life easier, they can’t get exactly the opposite. It’s just stupid and someone has to answer for this, because this is called SCAM.

It is not good to rant. But honestly, upgrading macOS is more like walking into a minefield now. I’m doing so much research and keeping notes just to be careful. Because it’s quite likely something could go wrong and I need to know what. I had to roll back several times with the past few releases. Monterey is the only okish one (buggy with bt tho), but I upgraded around 12.5.

FWIW I had exactly this problem after upgrading to Ventura on my Mac Studio. The two external drives (2 x MyBookDuo 28TB) were taking up to 30 seconds to mount and populate with folders. For me, deleting CP210xVCPDriver from the Applications folder restored everything to the original speed. The driver reinstalled itself on the next startup.

I have no idea what was really happening though, but this might be helpful to someone.

I had an old Macbook Pro 2017/18 and this Crucial X6 1TB SSD was great, transfers of 50GB in like 5 minutes under Monterey.
Now I just got the new M2 Macbook Air running Ventura and the same drive can take ages to transfer same size of a folder or file.

I have addressed to Apple Support on twitter but i don't know if it will help or not, latest update on OS seems to have improved the speeds a bit.
 
After recent OS update i can see speed update. Not as it was on Montrey but a bit better
 
MacBook air i7 2022, upgraded to macos 13.0.1, internal hdd ssd and external ssd... improved readiness in copying small files but little or nothing changed in copying large files (e.g. 1gb), long wait before starting copy and extremely slow transfer speed... problem not solved
 
Hello,
Just wanted to follow up on this. I have a SATA SSD 2tb in type C enclose. When I copy files from mac to SSD and other way around, the speed is decent. 2-3 mins for 55-60 gb transfer
BUT when I try to download any torrents directly to SSD, the speed is slow, some times finder or torrent client freezes (tried uTorrent, Transmission and others)
this happens on exfat and APFS.
Anyone else has the same trouble? Wondering if this is an enclosure issue or something in Mac OS.
M1 Macbook air

@lvleleven How did you open the trouble ticket? Tomorrow I'll open one for the same issue, maybe if enough people open tickets that will get the problem on their radar.
 
So an update, I’ve had to wipe my mac and reinstalled Monterey from the boot menu, can confirm speeds are back to normal. I don’t think apple give two ducks about it.

I’ll update to Ventura when the next OS gets released. I’ve been severely burnt by updating on launch, never again.

I'm not having this issue. For anyone tracking stats, here are the details...

2016 MBP, running Ventura 13.0.1 via OCLP 0.5.1, upgraded from Monterey 12.6.1. Samsung 860 EVO in a USB 3.0 enclosure, formatted APFS. 429MB/sec write, 425MB/sec read, which is about what I'd expect.
 
After several days of desperation, I have completely solved the problem by formatting APFS.

I used a Samsung T7 SSD with the factory format in a Mac Studio.

Now, after formatting, I have tried moving 280 GB (many thousands of photos and videos) and it has done so in about 4 minutes.

I hope this solution will help you!

Unfortunately using APFS isn't a solution when the flash drive is used on non Mac systems.
 
Having a similar issue with an external USB 3.1 SSD from LaCie. When I go in, there is a EFI that is in the FAT format while the rest of the drive is APFS. Could that be the issue? I don’t know enough about external SSDs to understand why both formats are on my drive. It was fine until upgrading to Ventura. Now I’m getting USB 2.0 speeds. So frustrating! Any help is appreciated. I remember a different issue when Monterey came out. On that release I initially had to wait upwards of 2 minutes for the drive to even show up.

If Apple weren’t so stingy on storage none of use would be going through this. I’m not paying Apple’s ridiculous SSD upgrade prices.
 
If anyone with the issue updates to 13.1 let us know if it resolves it here 😎
