Slow SSD speeds

[s3379665]

Hey Guys,

I just recently made a new build that cost me a pretty penny!

I inserted 2 SSDs!

1. 512 GB SAMSUNG 960 PRO (used for OS system)
2. Intel 600p 1 TB

It got set up by the retailer and they installed all the drivers. I turned it on at home and wanted to test it out and i tried to transfer a 4 gb folder that contained about 4000 items and the speed transfer were pretty low as to what i thought it was capable of. The file transfer would hit 250 mbps then it would dip down to 512 kbps and was not stable at all.

Did a crystalmark test

do they seem right?

Build has
cpu: i8700k
GPU: ASUS1080 ti OC
RAM: 32 gb ram
MB: apex X motherboard asus

Does this sound normal or is there an issue?

When theres a bunch of files all different sizes, transfer rate will be up and down, not consistent.

Copy a sinlge large file for us.

I tested CrystalDiskmark with my 960evo, and I came out just below yours in every test, except on the third row, where Yours was around 90% faster.
Seems legit. Have you run Samsung Magician on the drive? If not do it.
Btw if you bought 32GB for overkill like I did. You can probably turn of hibernation and the swapfile and then free up alot of SSD space.

How to turn of hibernation;
start -> cmd (run as administrator)
type
powercfg.exe /hibernate off
then reboot
if you need to turn it on again, same as above then type
powercfg.exe /hibernate on

For Samsung 960 and W10, there's a new driver (v2.3) that helped me: http://www.samsung.com/semiconductor/minisite/ssd/download/consumer/

I'm on the 2.3 Drivers. Just didn't know they where new.

What's the FW on it ? There was some flap about v3xxx lately.

This is the trasnfer files i was talking about - https://imgur.com/a/l93NJ

Now with one file 4 gb it took about 3 seconds - which i think is fine but i assumed that the above image that has 4000 items at 4 gb would take longer but not drop down to 1mbps or even as low as 128 KBPS

How would i know the speeds i am getting for each SSD is the correct amount? Is there a list that tells us what speeds we should be achieving? basically can i compare my crystalmark results to any benchmark speeds for the samsung 960 pro and intel 600p SSDs?

Any file transfer is limited by read and write speed of slower one minus overhead like from an AV etc. Looking at both disk's benchmarks and real life transfer it looks like your overhead is high, disks look like are running fine.

 

[s3379665]

As it is a complete new build straight from the shops, what overhead would be slowing it down? What is overhead and why would it be high? I am really bad with this stuff so i apologise for being slow

 

[GenRabit]

If the Antivirus has to check each file. that's gonna slow it down. That's overhead. Also seek time has to be taken into consideration.(although on SSD's that should be very very low)

I did not have an antivirus installed, it was a fresh installation of windows and downloaded all drivers for each component and then ran the crystalmark test. I do not think there is a high overhead on the PC. I assume that the transfer rate would settle at around 300 mbps and fluctuate around that mark, not dip down to 1 mbps
