How can i have a VPS or Dedicated Hosting Plan with unlimited Disk Space?

I Have a dynamic photo-sharing site and in case of high traffic it over-use the hosting CPU so Hostgator blocks my site. It happened like 7 times this month. I want to upgrade to a VPS or dedicated plan but both have limited Disk Space. It is photo sharing site so sooner or later the Disk will be full. And i can't risk it by deleting those pics. So how can i have a VPS or Dedicated Hosting Plan with unlimited Disk Space? BTW i'm using WP

Disk space is finite. You can't.

There are 2 ways to have alot of disk space and such, but you will be paying.
1) Get a CDN with a place like Amazon ( Amazon AWS ). You pay for disk space and bandwith but separately. Upside to this is you can use their service with a cheap host and still be able to push alot of bandwith and space.
2) It's similar to the first, but get cloud hosting. It clusters servers together essentially so you can have alot of anything.

unlimited space will cost unlimited dollars.
"unlimited " is just a marketing thing, you will get suspended when you will hit the "unlimited" limit.

On a regular shared hosting plan, you are more likely limited to 250k files. It is written in the TOS of the services providers.

With a dedicated or a VPS, you don't have such limit of inodes, but unlimited isn't existing that's for sure .

How many pictures are added dayly ? If you want you can contact me on skype and we could think of something for you.

Hit me up a PM and I can workout a deal on a VPS or dedicated server for you. I have unmetered bandwidth plans and also, my prices for hard disks are very cheap.
