SanDisk Extreme GO 64GB write speed problem.

Hello Everyone,


Few days ago I got a new pendrive: SanDisk Extreme Go 64GB USB 3.1 Gen. 1.


I have plugged it into my laptop with USB 3.0 USB and I started testing this pendrive with ATTO Disk Benchmark and CrystalDiskMark.


The average write speed was: 38 - 40 MB/s

The average read speed was: 140 - 145 MB/s


I expected speeds to be:

Write: ~150MB/s

Read: ~200MB/s


I thought that the pendrive was faulty and today I got it replaced with another, new pendrive.

I started testing right after unboxing and speeds are the same as the first penrive I had.


I would like to know what's wrong, because I saw reviews on the internet and people are getting better write speed than 40MB/s. Also SanDisk is caliming, that the speeds should be higher than 100 MB/s.


I have previous version of this pendrive, SanDisk Extreme USB 3.0 32GB and the speeds are higher than 100 MB/s, so my laptop is fine.


Thank You in advance.
