Hi everyone
I own a Samsung SSD 840 EVO 500GBs model.

Coming from an HDD as you might expect I'm very happy with this SSD.

I recently make a speed/performance test on the SSD, these are the results:

CrystalDiskMark
READ 689.3MB/s
WRITE 1140 MB/s

I know this is high because when I first got the SSD I tested it with the same program and the results were good but not that high if I remember correctly it was something like:

CrystalDiskMark
READ 500 MB/s
WRITE 450 MB/s

I´m not running any kind of RAID here besides a RAM Disk of 4GBS.

Another test performed by another program showed somehow similar results:

As SSD Bechmark
READ 964 MB/s
WRITE 1117 MB/s

Are these results the product of a bug? don't take me wrong I'm not complaining, I mean the EVO is really fast but I dont think those numbers are correct.

What confuses me most is how dramaticaly "improved" the write times are!



Any help on this matter would be highly appreciated.




These are my computer specs:

MOBO: Asus P8Z77-m
CPU: intel i7 3770K
RAM: Corsair vengeance 8GBs @1866MHz x4 (Total RAM installed 32GBs)
SSD: SSD samsung 840 EVO 500GBs (As primary boot disc)
RRD: 4GBS of 1866MHz DDR (For swap file, windows, browser temp, etc)
HDD: Maxtor 250GBs
VGA: MSi GTX780 TF2

Windows 7 Ultimate 64Bits +SP1
System is not overclocked in any way.

Hi,

I think that your benchmark is also influence of your 32GB RAM and the presence of the 4GB RAM disk. Just a thought

Thanks for your reply.

On the Bech tool only the SSD is selected ... could it be?

Well, you can try running the tool with just 8GB RAM and see if you get the same results.

Did you enable RAPID mode in the Magician software? that could be why you're seeing numbers that high.

This has got to be it. RAPID can achieve these numbers.

There are 2 possibilities:

1. You might have used the Samsung SSD Magician to enable "rapid mode" but I doubt it.

2. The ramdisk is probably responsible for the results. I just happen to have a Samsung 840 EVO 256 GB ssd and 32GB of system memory. I use 20GB for a ramdisk for certain professional applications. It produces synthetic benchmark results even more insane than yours. I normally do not pay much attention to synthetic benchmarks.
