I found a very reasonably priced, now discontinued Samsung Portable SSD T1 (Model MU -- PS500B) at a nearby consumer electronics store. Manufacturing date is 03/2015. Not the latest&greatest, but for 129€, it seemed like a bargain. Worth a try.
From the comments on Amazon, I knew that installation was not painless and many had complaints. So I decided to "unlock" the drive on my Windows 10 PC and re-format it on the MacBook later.
In Windows 10 the drive did not show up with a driver letter, so I couldn't install the software required to unblock the drive. I had expected to see a "tools"-Partition or something like that
The manual was not helpful either.
|There is a new drive!|
|But it looks pretty useless|
No tools or utilities partition and no driver CD in the box. Gooooogling helped:
I found the T1 Activation Software here.
I then extracted "SamsungPortableSSD.exe" from the ZIP Archive and ran it.
I choose not to use a password and a few moments later, the drive was accessible:
|Re-formatted to NTFS|
|Shows up as expected|
|Yes, we're sure!|
