Question Random read and write speeds much lesser than the specified rating (Samsung 860 EVO)

[Ali Tauseef]

Just what the title says: using the Samsung magician utility, I'm only hitting 65K IOPS random read and 57K IOPS random write speeds (4KiB, QD: 32, T: 1) while the specified ratings are far higher (98K and 90K, respectively). The sequential speeds are just as mentioned though.

Should I be worried?

how full is the ssd?

how full is the ssd?

213 free out of 465GB
I tried CrystalDiskMark just now to check the random speeds: got 83645 read and 72563.2 (I converted from MBps to IOPs by using: Speed in MBps / 4 * 1024).. but that still seems a bit too low?

Can you run AS SSD benchmark and show screenshot with results?

Note. On OS drive (where windows is installed) you'll get lower benchmark results. This is normal.

spec is up to. smaller drive are slower. and empty disk is faster too

Of course! But how much should the difference be?

Result is very good.
Don't know, what you're worried about.

did you clone it from a hdd?

MB2000EAZNL HP 2-TB 3G 7.2K 3.5 SATA

and why did you said it is 465GB?

yes

and why did you said it is 465GB?

it is 465GB, i got the 500GB variant

Result is very good.

I can't really make these scores out, how does it translate to random read and write speeds?

4k - random reads/writes.
