i want buy hosting in dreamhost, webhostingpad, Servage and site5 If you choose, which one is better? thx
None of them. Each of them are massive oversellers, who offer space/bandwidth, which you are not going to use, & ban you if you use it. I would suggest you to think about how much space / bandwidth you actually require, & you may actually save money by not going with any of the above mentioned hosts Ishan
Agreed, don't go with those look further before you decide. Check out hostmonster / bluehost, hostgator, and lunarpages.
If you are looking for stable and with good uptime have a look at Utropicmedia.net. They are not biggest then the ones you have mentored, but more experienced for sure. And the quality level is very high.
