Is it acceptable performance of NVMe?
I have bought a server with NVMe. I tested its speed as follows and confused about its performance.
Is it ok?
[root@server ~]# hdparm -tT /dev/nvme0n1p1
/dev/nvme0n1p1:
Timing cached reads: 19620 MB in 1.93 seconds = 10144.70 MB/sec
Timing buffered disk reads: 4096 MB in 1.51 seconds = 2712.62 MB/sec
[root@server ~]# hdparm -tT /dev/nvme1n1
/dev/nvme1n1:
Timing cached reads: 18822 MB in 1.94 seconds = 9718.28 MB/sec
Timing buffered disk reads: 8010 MB in 3.00 seconds = 2670.00 MB/sec

Can't you read those numbers? Eat a dick.
Wtf is wrong with this guy?
Not enough dick in his diet, obviously.
what happen to my eyes
Not sure but from the look of your avatar not enough crack or too much crack.
yeah ... that benchmark number blow my eyes and the title shrink my pupils
Hello overconfident guys. You cant realize the reason of my asking due to your limited view. Maybe, You have seen a limited range of nvme numbers.
I have got 2 other nvme server which are just double of these number. but those are
NVMe with M.2
and my concerned server is NVMe with U.2
So I became confused. If it is ok?
If you are looking for nice people that treat you like the princess you are, you are in the wrong place.
@volver gotcha back bro.
Eat a dick.
@WSS Eat a bag of dicks
@volver thanks but I'm full. Here's yours.
@WSS Sorry, didn't knew you already had your dose today.
@volver Any time your shitty SEO comes around, there's plenty of shit for the dicks to feast on, sir.
Not doing any SEO since 2012/13.
Soon I plan to spam LET with nike/adidas articles that will lead to my other puma articles. And I will sell tons of snickers, and you sir, will buy them either you like it or not.
Change it from snickers to Hersheys' "Skor", and I'll put you on the shitposters' payroll.
Ah, crap, I wasn't supposed to talk about that.
Hand over your official card, the sperm tester, forget the secret handshake, and gimme the keys to the clubhouse.
How are you supposed to forget how to jerk off?
Ask @AuroraZ's wife.
I need that big ROI, chocolate is shit. I will start spamming ads right now.
Not my problem. We kept warning you and you could not stop talking.
I'll just ask your waifu.
Your performance is good. If your name of "noderise" means you're about to be a new provider, then you probably have a lot to learn.
Here is my RAID 10 of regular SSDs (8x SM863a 1.92TB each);

Thanks for your answer. I am learning. and I know its good but I have got two other systems those speed are150% to 200% better than this system. So I am asking to know which one industry standard?
