This is kinda bull**bleep**, sandisk seems to ignore this issue and seems ok with it.
I bought a 128GB thumb drive to be used in my “mini-nas” but that seemed like a no go.
Started transferring files from my old server to new server onto the sandisk thumb drive and after like 20-30sec, the copy process just stopped. First I thought it was some other issue but then I noticed how insanely hot the thumb drive was. Found by various forum threads that the drive kinda disconnects after copying large files but small files (and not too many) worked ok.
Saw some replies from sandisk representatives that the heat isnt an issue and I decided to proove them wrong.
Here´s my “ghetto modded” thumb drive
Now it works and I have no issues with the thumb drive disconnecting when reading or copying files.
Thought id share it if anyone have any use for the info.
