SSD Performance on Aspire E5-576G

TonyinFL

I have an Aspire E5-576G with 8250U CPU, 16GB RAM, and the included 256GB SDD.  Plus I added a Samsung SSD 860 EVO 1TB to the empty drive slot.  All in all it works great and the real life performance feels quite good.  However the synthetic benchmarks seem lower than I would expect, particularly on the random IOPS (Input Output Operations Per Second).  When using the performance benchmark on the Samsung Magician software I get 39,306 and 31,738, for read and write, respectively.  I get similar values on the included SSD, but since it is a less known brand I did not know what to expect for its performance.  I would expect IOPS to easily hit 90,000+ for the read and 80,000+ for the write on the Samsung 860 EVO.  I wonder if there is something off with the SATA / AHCI implementation on my laptop that may be handicapping the random read and write scores and if so is this is a defect specifically with mine or due to build components is it expected performance for all of them. 

I tried using a 500 GB Samsung 850 EVO on my Aspire and it also showed degraded random I/O scores while the same SSD in my desktop got much higher values, so this does not appear to be an issue with a single SSD.  Sequential read performance is comes in great for both the included SSD and the 860 EVO i.e. around 560MB/s.  I believe manufacturers like to quote sequential I/O performance as it is usually quite good compared to random I/O.  But random  I/O is more typical of real world access i.e. accessing lots of smaller files as opposed to one great big file.  

Samsung Magician software will benchmark any SSD and is free to download.  I am hoping someone with an Aspire E5 can run the benchmark against a Samsung EVO and let me know their results.  I have attached mine.  And if you don't have an EVO perhaps feel free to just run it against what ever you have to see if it behaves similar to what I am noticing.  Thanks!

Eekobus - thanks for posting your scores!

I believe I have uncovered a few things.  I had Acronis Active Protection active during my original testing.  This attempts to protect against ransomware activity and as such seems to have a low level hook in the operating system to be able to scrutinize I/O activity.  When I disabled this my scores went up (see below).  However the Random (IOPS) scores still seem lower than I would expect.  I have a desktop that I used to have configured with an EVO 850 SSD and it typically scored MUCH higher for Random (IOPS), i.e. 90,000+ and 80,000+ for Read and Write, respectively.

I don't know the details of the Random I/O tests that Samsung uses for the benchmark in its Magician software i.e. queue depth, threads, file size, and total data.  Perhaps the Magician benchmark has changed or perhaps as designed it becomes CPU limited on a i5 laptop CPU vs a i7 desktop CPU.  Interestingly enough, when I run a benchmark on CrystalDiskMark with my Acer laptop I do see  MUCH higher scores for Random (IOPS) - note a queue depth of 8 and thread count of 8 on the results that are bold/italic. 

Anyway, with the CrystalDiskMark scores I suspect the 860 EVO is preforming nicely.

Hi guys, very useful data
Do you guys installed the ssd right out of the box? or it needs a special mounting bracket for the instalation
My pc is a Aspire E15 575G-57AV

Camilo318 - at first I just installed it without the mounting bracket but I eventually decided get and use the mounting bracket.
