Performance of Samsung 970 PRO 512GB SSD

Hi Folks,

 

I have upgraded my ThinkPad X270 with a Samsung 970 PRO 512GB SSD.  The drive works fine but when I run the performance benchmarks in Magician I get:

 

  • Seq. Read 1,684 MB/s
  • Seq. Write 1,667 MB/s
  • Random IOPS Read 124,023
  • Random IOPS Write 112,060

 

This is well below the documented performance as follows:

 

  • Seq. Read up to 3,500 MB/s
  • Seq. Write up to 2,300 MB/s
  • Random IOPS Read up to 370,000
  • Random IOPS Write up to 500,000

 

Now I accept that these are theoretical maximums but the gap is significant.

 

The ThinkPad X270 has the following specification:

 

  • Windows 10 Pro 64 bit version 2004
  • Intel Core i5-6300U CPU @ 2.40GHz
  • 16GB RAM
  • Latest version of Magician
  • Drive interface PCIe Gen. 3 x 2

 

Could someone please confirm if the above is to be expected or whether I am missing something?

 

Many thanks

it looks like ur computer is using a pcie 2.0x4 slot which is why ur speeds are what they are..

to get the 3,000 speeds you need pcie 3.0 x 4 slot...  check ur devices specs to see if this is the case.
