So on black Friday I bought the i5 128GB from Microcenter for $799. I come home and do some benchmarks noticed that the write speeds are about 3X slower than it should. Do some research and find that the Tablet has a Samsung SSD instead of Hynix SSD. I call a local Microsoft store and verify with a technician that all the tablets they have in the store have a Hynix SSD. This is extremely frustrating because Microsoft is swapping different SSDs with huge performance difference without letting customers know. So then I thought about. Microcenter was the only store that had the Tablet for $799. Amazon, Best Buy, MS Store, etc, etc all had it for $899 on Black Friday. It makes sense. So what I did is request a replacement tablet under warranty. The replacement is coming tomorrow and will let you guys what I find. This is just frustrating and I had to get this out and let people know. Anyone who got the Surface from Microcenter, check and verify the SSD you have peaks at 100-130MB/s for write. The Hynix SSD has write speeds above 300MB/s. I use AS SSD benchmark. Here is a review unit with a Hynix 128GB SSD (not Samsung) : http://www.notebookcheck.net/Microsoft-Surface-Pro-3-Tablet-Review.122170.0.html UPDATE: I got a replacement unit under warranty. Same tablet. So I booted it went through the setup nothing interesting there, the only thing I noticed is that the final set up was a lot faster. Right away went into Device manager, and see the Hynix Drive. Benchmarked get the expected results, I got 306MB/s sequential write previously I was peaking at 130MB/s.
