SSD performance really slow

[some guy named dave]

Hello,

I just installed a Samsung 850 evo running Windows 10 on it. I thought about encrypting it but I decided not to until I could perform benchmarks.

As it turns out, the benchmarks on it are quite poor even for a fresh install. Here is a screenshot of the benchmarks taken with Samsung Magician:

Optimization settings:

Note I also tried Performance mode and it was roughly the same.



Any ideas?

Thanks.

Two things come to mind:

1) What is your motherboard? If it is older and you have a SATA 2 connection you might be getting throttled by that.

2) Have you run the 'authenticate' feature in Samsung Magician to ensure it is a genuine product? We had another chap on the forum recently discover his was not, in fact, genuine and the performance was severely lacking.

I would try AS SSD, Atto or CrystalDiskMark first and see what speeds you get with them.
I found Magician to never be accurate.

I see a lot of other drives as well. They'll all be running a little bit in the background and using some bandwidth, unless they are on a separate controller. Might be skewing the numbers.

Try enabling RAPID Mode in Samsung Magician.

The motherboard is a Gigabyte GA-Z97X-UD5H (rev. 1.1) and the drive checks out as genuine.

The results from AS SSD are about the same. http://i.imgur.com/eDRvwPT.png

Try enabling RAPID Mode in Samsung Magician.

I'll try that in a moment and see what happens.

Edit - turning on RAPID mode resulted in much higher speeds, as the name would suggest. Here are those results: http://i.imgur.com/60Pj2Ny.png




Are there any potential downsides to using RAPID mode that I should be aware of?


Thanks.
