I've never had an issue with the short adapter... Been using it for a couple years now with my Adata 2TB ... no issues at all..
You and I had briefly gone over it before. So if your testament is for me, then it's meaningless. I have pretty good memory, and do not require repetitive reminders.
If your testament is for newbies to this thread, then you should properly disclose your usage pattern at the same time. Otherwise, like this testament, and your recommendation of SX8200pro over the years are misleading to newbies.
As I understand it, you use your laptop at home, often connected to a power brick. So your laptop is pretty much stationary almost like a desktop. That's what I called 'using a laptop as a desktop replacement' in my post that you just responded to.
For a mostly stationary machine, I doubt that you can find any difference using short or long adaptors. Perhaps lots of users in the audience use their laptops like you as a desktop replacement indeed, considering how old the batteries in these machine are (if not replaced since out of factories).
Laptops as mobile devices will go on daily commute trips, carried in bags/luggage, passed along single handly & etc. These situations are much more rough for a laptop than one mostly sitting stationary at home. I'm such a user. I regretted I picked the SHORT adaptor. A LONG adaptor will be a much better choice.
