850 PRO IOPS slow after OS is installed/migrated

JUMP TO SOLUTION

Hi All.

 

Ok so the problem is the IOPS went from well over 80,000 down to 30,000 after I migrated the OS using Samsung Data Migration Tool 3.1.0.3

 

I am using a Fresh install of Win10 1709

Downloaded and installed 01/24/2018 2 days ago

All current Chipset drivers from Intel/EVGA

 

Installed to a WD Black HDD, installed all of my software & drivers, any windows updates, etc..

Then Migrated the OS to the 850 PRO, booted up to the SSD,

Restarted a couple times for good measure.

 

Ran Samsung Magician benchmark, and the IOPS is down to 30,000

 

Is this Normal?, My friends say Star Citizen 3.0 loads in 30 Seconds, mine takes 3-5 minutes

Also to note, my system is much newer, and more powerful.

 

Here are my system specs.

SSD: Samsung 850 Pro 256GB (7.6 TBW) as of this writing (10% provisioned)

Motherboard: EVGA X99 FTW

CPU: Intel i7 5930K

RAM: Corsair Vengence 4x4GB=16GB DDR4 Quad Channel 2666MHZ

GPU: GTX780 FTW 3GB

APU: Soundblaster Z

PSU: X3 1600 Watt running in 1200 Watt mode

 

See Also this thread. was thought to be a chipset driver issue, but has been ruled out.

Thanks for input that might help address the issue, or prove this to be normal.

Any other information I need to add?

 

Thanks...

Problem Solved:


EVGA X99 FTW E997

Intel Microcode with Spectre updates BIOS 2.04

Rolled back to BIOS 2.03 and the IOPS are back to 100,585 | 60,302


Thanks.. Hope this info helps someone.

I think I am going to go back to my RAID which is much faster then this SSD.

Since I don't see why it is slowed down after migrating an OS.

 

My RAID0 with 5 WD Blacks has 5TB and is 3 times faster then the 850 PRO SSD, the IOPS READ is much faster also.

I can even add another one for a 6TB and even faster.
