I am experiencing very poor SSD writing performance in my Surface Book. It's i5 dGPU 8GB RAM and 256GB storage model. Installing applications and copying files have been really slow. Windows 10 is updated to the latest. Has anyone having the same?

Disabling BitLocker slightly helped (10~20%) but not very much.

    Mine (i5 256GB) Pro 4 is even slower, with sequential writing 88MB/s and 4K at 0.87MB/s. Horrible speed!!!!

    And I also have battery drain, loss screen touch response, camera won't take picture, Input personalization server using more than 30% of CPU all the time. and so on.

    I'm getting similar numbers. What speeds should we expect from the SSD in the Surface Book?

    Well I ran tests from Crystaldisk and HD Tune, and the results from them are reasonable... I'm not sure if the problem is real or just from buggy testing tool. If someone can test his/her test result with AS SSD Benchmark, that would be great
