Hello there!

I purchased a Samsung T7 Shield 2TB back in 2022 and have been using it extensively as my main SSD for editing footage and other tasks. Recently, I returned from a work trip during which I didn’t use the SSD for about 6–7 months. Upon plugging it in again, I noticed the following issue:

Sometimes, the disk becomes extremely slow, with write speeds dropping to as low as 2 MB/s. I thought it might be a firmware issue, so I updated it using the Samsung Magician application. After the update, the speed improved, and testing showed a write speed of around 850 MB/s.

However, subsequent tests revealed inconsistent results. Sometimes, I get the expected 850 MB/s, but other times, the speed drops back to 2 MB/s. This issue occurs on both macOS and Windows.

Is this a sign that the SSD is failing? Or is there something else I can do to fix it?

Thank you in advance!
