Surface book 2 i7 8GB RAM 256SSD slow SSD write speed

Question

I've bought Surface Book 2 with 256 GB SSD storage and gettings strage write performance

I've search for same issues on microsoft answers and reddit and found a lot of threads regarding Surface Book 2 (and other surface lineup) SSD slow write speed. 

But I didn't find any exact answer from Microsoft representatives is it "**by design"**or not.

I can definitely say that all surface books 2 with same 256GB SSD in my local store have the same write speed.

512GB model in our local store have approx 620MB/s

1TB models in our local store have aprox 1200MB/s

So my question is if it is normal write speed for 256GB models and intended to be "by design" or I should send my surface book 2 back to microsoft for repair?

Answer 1

I have same problem

This is not normally a notebook for 2800 euros SSD write 340MB !!!!

Answer 2

Here are my stats.  My sequential writes were faster but reads are slower.  Not sure what to do to change this for the better.

The only thing I changed was this within the disk drive properties.

Answer 3

That going according to my previous remark

"I can definitely say that all surface books 2 with same 256GB SSD in my local store have the same write speed.

512GB model in our local store have approx 620MB/s

1TB models in our local store have aprox 1200MB/s"

Also turning on Windows write-cache buffer flushing on device gives zero performance boost.

Seems like for whatever the reason TurboWrite is dissable for Samsung SSD on SB2. I hope Microsoft support will give us an official answer

Answer 4

I have the same problem!

Is bitlocker still enabled, I have almost no speed more. I hope Microsoft fixed that!
