My db is currently around 650mb but is is increasing with around 500 concurrent users doing transactions and reporting at the same server. Please let me know whether the following changes can improve the performance or not.
1. Moving mdf,ldf,tempdb to seperate drives.
2. Create 2 server one for transactions and one for reporting ,replicating data to second server through always on or replication mechanism.
3- changing the current raid 5 to raid 10 in first server or both.
What other changes i need to bring to improve performance , becouse some of the query is performing very slowin the server . can i expect performance gain by doing the above tasks.

Yes, you want to do that anyhow but yes, do that.

2. Create 2 server one for transactions and one for reporting ,replicating data to second server through always on or replication mechanism.

Yes, this will help tremendously. As a general rule it's best to separate your OLTP and reporting. Plus, with a reporting server you can index the heck out of it and do a lot of other things that you don't want to do on your OLTP system.

"I cant stress enough the importance of switching from a sequential files mindset to set-based thinking. After you make the switch, you can spend your time tuning and optimizing your queries instead of maintaining lengthy, poor-performing code."

The usual process of identify the slow queries, tune them (indexes and/or queries). Repeat until performance is acceptable.

thanks Alan Burstein,Gail Shaw for you feedback , my point was the same query will perform differently when i execute that in local pc and in server , i will move for separating the server due to load of users on server hard drives,processor,memory and heavy report generations crystal report and etc.. and see how it works.
