Surface Pro 4 experience: Part 2

So I was trying to SP4 to do a quick sketch, and found that the new Surface takes FOREVER to wake up from cold.  To be precise, it took almost 5 minutes to boot up,  Due to it's form factor, I kind of expect it to wake up much quicker.  Maybe it's just that one time, since I did started SP4 from cold in some other situations and it was working ok.

Knowing that SP4 has a microSD slot, and being a storage hog, I want to maximize the storage that I can use.  So I brought this Samsung - EVO+ 128GB microSDHC Class 10 UHS-1 Memory Card and inserted it in SP4.  Maybe I had too much expectation because of this "UHS-1", so I was not too happy after seeing following tests I did:

• Sending 40.4Gb application files (with executable binaries and all setting files): took 43 minutes.
• Sending 61Gb multimedia files: took 50 minutes.
• Sending 17Gb multimedia files: took 10 minutes.

It still usable.  I was just expecting more.  Also I was told that there's this microSD ejecting itself problem on SP3.  Let's see if SP4 has the same problem or not.
