i want to build a file hosting web.. need a large disk space.. and most of unlimited plan does not allow me to host a file hosting website.. is there any others?
I will try and give you the best answer I can based on cheapness (as you don’t want to pay a fortune when setting up) and also quality (you want to build a reputable brand of file hosting).
So your best route would be to host your website on a shared hosting plan at first, these are the cheapest forms of web hosting available through most web hosting providers, and are also the most reliable as they are fully managed for you, and have almost no downtime (if you avoid the free ones).
Once you find your service is becoming more popular, you can ad adverts to it using either Google Adsense or something similar, where you can start to earn money from your visitors. Once you do this, by the time you are earning enough money from your adverts, you will be able to afford to purchase a dedicated server, which you will have to manage yourself, but will be the only option once your file hosting service becomes "big time".
So to conclude, start off with a shared hosting provider. In my experience www.belira.com is the best for cost and most importantly reliability and support. Their plans are not unlimited meaning you will always get good server response times ( as unlimited web providers basically oversell their space and the server runs slow as it is bombarded with files).
Then once you start to hit the limit (once you get thousands of uploaded files) you can move to a dedicated server, and pay for it using the adverts you have added to your website.
After that sit back and admire all your hard work
