Inspiron 5570, SSD read speed?

The system doesn't  -- for power/cooling reasons, and for market position -- likely elements of both.

This isn't a high performance system - nor is it designed and built with an elegant cooling system.

I think you have already found your answer in this thread:

Like @jphughan already wrote: Dell 5570 is running in  GT2 "low power mode" rather than the GT4 "max performance mode".

Sorry there isn't a better answer!

P.S.
Dell Inspiron 5570 (2017 Model), 960 EVO NVMe   - Windows Boot time is 19 Secs :Crying:
Dell Vostro 3750 (2011 Model), MX 300 SATA-600  - Windows Boot time is 8 Secs :Zipit:

Thanks for your response.

Yes I found that. 

But the Processor Intel i7-8550U supports GT4

Then what is the problem with Dell 5570 ? 

Please help

@ejn63 I think you are right, unfortunately...... (but it's sold as a high performance system, including the prize (~€950))

It's a mid-range system at best -- or for gaming, decidedly bottom of the line (aka entry-level).  The inspiron series anchors the bottom of the notebook market for Dell (and all the others have similar budget lines).  In these you don't get sturdy metal chassis, high-performance drives, standout screens, etc. -- they are built to a price, just as the Corolla/Civic/Cruze/etc. models are in the auto world.

The XPS models are the beginning of the performance lineup -- and even those are at best mid-range for gaming.  You don't get to high performance until you hit the Alienware and Precision workstation class of system.

Thanks for your response

But I think these may not be any reason for not getting the SSD speed, the poor built quality, display quality, the entry level GPU etc never affects on SSD speed where physically it has PCIe Gen 3 X 4 NVME Interface, and the CPU who supports GT4 which is technically required for Samsung 970 Evo's optimum performance. 

It may be that Dell intentionally somehow bottle necked it (not for heating issue, because I run my PC daily 10 to 12 hours, playing games constantly for 3 to 4 hours, Audio & Video production for 7 to 8 hours... never found any heating issue) which may be recovered by an upgradation of BIOS. 

I talked with a Dell guy, he also told me that a BIOS upgrade can fix it and Dell is working on it... I don't know what is true :smileylol:

I am having the exact same problem with an Inspiron 5570 and the Samsung 970 Pro NVMe M.2 512GB SSD.  I just updated the BIOS to 1.1.6.  I have switched the SSD to AHCI and write cache is enabled.

I tried taking to Samsung and they said that they couldn't even find the 5570 specs on Dell's website so therefore they're blaming the computer's output speeds for the SSD only meeting 1/2 of it's performance benchmarks. I'm so glad that I wasted a half hour of my life with that phone conversation.    

Here my Samsung benchmark results (BIOS 1.1.6 / Windows 10 Home):

@smspeight Thanks for calling!

I contacted with Dell Support, they remotely tried to solve the issue but no positive result found. Then they decided to replace the mother board and yesterday Dell technician came to my place along with a new mother board, replaced it, but no better result.

After few hours of war they told me "Unfortunately it does sound like some kind of compatibility or product limitation. What exactly it is, I can't say for sure. Thank you for bringing me your question." 

(I really appreciate Dell for their support and endeavor to solve the issue, thanks to Dell).

However guys be happy that we are getting  3 times faster speed than any SATA SSD,  system is booting in seconds and applications are opening on just a click. 

I want to share

Dell just now called me again and assured me that they are going to solve the issue. 

(I don't know how and when)
