Sandisk Extreme Pro 2T unreliable/unusable on Macos Ventura

This is 2nd unit of Sandisk Extreme Pro 2T in a few days, as I initially thought the problem was coming from the first unit. I send back the first unit and ask for a replacement. But same thing. It seems to be a MacOS problem. I’m running macOS Ventura 13.2.1 on a MacBook Pro 2019.

After a few hours or couple of days, the Sandisk Extreme volume becomes unresponsive and all the data in it are lost. The device lost the content, even its name. Remounting the device, formatting it again will only allow repeating the same disaster few hours or couple days later.

Needless to say that this is totally unacceptable nor even thinkable.

Does anyone has experienced this. Sandisk support, any advise?

Hi

thank you for this suggestion. However i didn’t open a support case, since meanwhile I have returned the device (the second unit) for refund. Reading different forums, it seems that this is a compatibility issue due to the fact that the Macbook Pro I have is a 2019 with Thunderbolt 3 ports that supports up to USB 3.1 Gen 2 @ 10Gbps, whereas the Sandisk Extreme Pro is using USB 3.2 Gen 2x2 @ 20 Gbps.

I cannot tell if the issue is from Apple or from Sandisk (i.e not gracefully back falling to USB 3.1 Gen 2), but I don’t see this kind of issue solved in a timely manner, while at the same time, users lose their data like hell with this combination.

Since I cannot leverage the full speed of the Sandisk Extreme Pro anyway, I"ll go for a native 3.1 Gen 2 SSD drive, proven stable.

Any luck here mate? I’m running into some similar issues. Curious if you found stability in anything.

Honestly, if you still have issues with this (i.e July 2024), whereas this thread was created March 2023, assuming drivers & OS are up to date, that means that nothing has been done Apple or SanDisk side to solve it. In this case, move away from SanDisk. I personally opted for a Samsung T7, which although having less read/write speed, doesn’t matter in my case since the USB port I have cannot do faster anyway.
Good luck

Thanks for the candid feedback!

I doubt our issues are the same, but reading your notes about the downgrading had me curious. I had random problems with the drive acting like a spinning disk - brutally slow.

I found some faulty cables that may have led to my issues. I had repeated issues with one of my drives, and, using new cabling, I have had 0 issues. I swapped to a new 20GB cable even though it can’t use half of that. I have had to format this thing a few times, but I’m unsure if it was the drive or the cabling.

I’m glad you found stability. Have a great day!
