How is the speed of SSD disks divided on VPS?

Question

Solid State Drives

Hello. Do I understand correctly that a VPS server is one VDS on which there is something similar to a Virtual box, and the resources of the main VDS are already divided into small VPS in it?
Many different hostings offer VPS services with fast SSD drives, but if for example it's all on one VDS and nearby small ones are all busy and 100% loaded in terms of disk, then what will be the speed of my VPS? Minimum? Then it is no longer an SSD, but something ordinary due to the load of those nearby.

Answer 1

VPS is VDS or as it is also called a virtual server.

How is the speed of SSD drives divided?

It is shared as configured by the hypervisor administrator. Maybe equally, maybe not equally.

what will be the speed of my VPS then?

But who knows how it is configured there and what kind of overhead. Maybe there will be more or less adequate speed, maybe even around zero.

Then it is no longer an SSD, but something ordinary due to the load of those nearby.

Of course.
SSD on VPS is nothing more than a marketing headline. And the speed and most importantly IOPS depends on the settings and the load on the host.

Answer 2

Usually it is not allowed to load the disk subsystem by 100%, but this is on normal VPS.

No, VPS and VDS are the same thing.

Answer 3

If you take a cheap host, then everything will be loaded at 100%, if you take something at an average price and with a good level, then you can get a fast one with "ssd".
I took the cheapest host for the first time (like a justhost), then a friend showed me how everything is loaded on xelent - I was surprised. Even though it says "fast ssd"

Answer 4

As the hoster sets the limits, they will share.
There can be hard limits on I/O or no limits with priorities. Maybe not at all.

Answer 5

for large providers, the disk subsystem may be generally separate from the server part. The network storage is simply mounted and distributed over several VDS, then one more.
The load is watched in such a way that it does not exceed a certain limit.
This is done either by limiting according to your tariff, or by scaling if there is not enough performance already.

each VPS user, the i / o limit is indicated in the VM settings,
we can also change the disk type on request, for example, ssd to nvme, if the speed is not enough.
