Is this SSD or HDD? Please take a look.

Hello. I'm having some hard time with some provider. I will write something about them and their name after you say what you think.

I bought a Vps server. Their website claimed it was raid10 SSD server. But benchmark result says different.

I think this is HDD. I contacked with the support team. They said It was pure SDD and They never use HDD.

Is This HDD or SSD?

    looks like an SSD to me. Random IO speed is good. my HDD never gives more than 1-2 MB/s

    By the way, taking the opportunity I wanna ask people.
    How the 4kb block size influences on browsing webpages?

    Which one would be better for website? Stats says that 4kb blocksize 235.59 MB/s read will be better than 159.11 MB/s read. But will it be really faster while browsing my site? Given that the cores and RAM are the same, the network's the same as well. Thank you.

    in those Random 4kb blocks yes.

    You don't need speed tests, you need latency testing. Either way, these speeds would be negligible real world difference to the end user. They are more than acceptable and I'm sure surpasses your network speed.

    Thanks for your answer. As far as I know, Cloudflare improves latency. So if my server in UK, using CF DNS, people from Poland, Serbia and even Turkey should have almost the same latency as people from the Netherlands or Scotland. CF anycats... Am right or mistaken?

    BTW, LET and LES both using CF, and I can say that LET is a little bit slower than LES for me, maybe because I'm from Europe and LET servers must be somewhere in the US, and as far as I know LES server in UK. So IDK to belive in CF anycast or not.

    anycats thinks you are mistaken.

    I'm not sure you understand the difference between Cloudflare's public anycast DNS service and Cloudflare CDN service, or what each of those services do.

    Also, it depends on whether content is dynamic or static, how busy the sites are, etc. The first person to request certain data will always see higher times than the 2nd guy who requests the exact same data.
