Samsung 960 Evo 500GB Ain't alot faster?

tomtom1298 · May 5, 2017

Hello!
Today i've installed my new M.2 960 Evo 500GB (3100/1900) But i when i use Samsung Magician the performance are hard below it. The results are: 823/796 (R/W)
It's slightly faster then my normal SSD.
Is there any reason why i can't read the 3100 Read/1900 Write?

Tips, Tricks?

Thankyou!

You want to verify you slot is a NVMe slot as well. And you do know that those are best case scenario, right?

My Whut slot?
And i know 3100/1900 is at the best moments yes. But 1000 was the lowest thinkable perfomance i was thinking.
So xd.

My Mobo is: MSi Z97S Sli Krait Edition.
M.2 Slot - 1x 2280 Key M(PCIe Gen2 x2/SATA)

Your M.2 slot is to slow for the SSD. They are made for the Gen3 x4 slots for max performance.

oooohw... Smart ass me xd. But atleast. It's an upgrade

Should still be fast, overall. The rated advertised speed is always in benchmarks for the most part, though in real-world use they still outclass SATA based SSDs with software than can push them to their limits.

It's the IOPS of the drive you'll really feel in the real world anyway. Not so much the sequential speed you're benchmarking. I'm curious what max IOPS your getting.

The Results you requested.

Yeah not too bad. Not to full spec of the drive but not surprising as it's only got two lanes to operate over. Still double the IOPS of SATA

marko55 :

The read is 2.27 X time faster (IOPS)
And Write 2.53 X time faster (IOPS)

But, what's IOPS exactly? i'm not sure what it is. Something with handling i thought?

Input/Outputs Per Second. How many reads and writes can your drive handle every second. This primarily applies to very very small file reads & writes (like 4Kb) on your drive. This number comes in to play when loading your OS as that process is reading a lot of small files. Also while running many applications, including games. IOPS play HUGE with things like databases as there are many very small reads and writes to DBs.

The big number many get hung up on is the sequential performance (2500MB/s, 1800MB/s, etc). That applies for reading and writing larger files (by large I mean like 1MB and up).

For instance, if you have a 2nd SSD in your machine, and you copy a folder that has say 500 files in it of various sizes totaling 40GB over to it from your NVMe SSD, you'll probably see your transfer speed bouncing around between 10MB/s all the way up to 300-400MB/s at times. The dips are when the smaller files are being hit. The spikes to 300-400MB/s are while its moving larger files.

Now you take that 40GB folder and zip it up to a single zip file. Now copy that single large zip file over from the NVMe SSD to the SATA SSD and you'll see your transfer speed sit at the max write speed capability of the SATA SSD you're copying to (maybe 300-500MB/s depending on the destination SSD) throughout the entire transfer. This is because its one big sequential write.
