[SOLVED] Awful sequential speeds with new Samsung 860 Evo

Solution
No it's not, but from what I can tell all the sata ports on my motherboard (Maximus VIII Hero) are 6Gbps ones. Magician also reports i'm using a 6Gbps port.

It's it currently my boot drive but I ran a benchmark in safe mode and the results are the same. I tried the Magician and the results are slightly worse >_<

In the grey Intel port, or the black ASMedia port?

Have you checked with Samsung Magician? Is the latest firmware for the drive installed?

Also that figure between storahci and the drive capacity is the alignment. It shouldn't be like that. You need to realign the sectors for it to work properly and faster.

You can use MiniTool Partition Wizard Free from here to realign the sectors. It might be safe but I strongly advise you backup any data you have on the drive before attempting to do that. Things can go wrong in the process and when dealing with storage that already contains data it's always best to have backups.

If the alignment is fixed the drive should perform better.

Yep, using the latest firmware. Thanks for the suggestion. I'll give it a try now.

You can double check the alignment before doing that too.

Just type msinfo32 into run box and System Information opens go to components > Storage > Disks and in the panel find the SSD and check “Partition Starting Offset” value. Whatever the number is evenly divisible by 4096 or not.

If there's no decimal remainder, the number is evenly divisible. That means the sectors are correctly aligned on the drive.

I tried that tool but it just tells me the drive doesn't need aligning. When I check MS Info I get:

555,745,280 divided by 4096 = 135680

Have you checked with Magician benchmark too? It just does sequential and read/write IOPS.

I checked my 840 Pro with Magician and AS SSD three times. Magician results are more consistent and AS SSD results are all over the place.

Mind you, this is a system drive.

OK so the sectors are aligned. Is this the system drive, where Windows is installed to?

Is it on the first SATA port?

No it's not, but from what I can tell all the sata ports on my motherboard (Maximus VIII Hero) are 6Gbps ones. Magician also reports i'm using a 6Gbps port.
