fine tune the data access for very large data without Synchronization

I have to fine tune the data access for very large data. Here is the details:

1) I can use any Collection to store data. Want to use ArrayList so that random access possible.
2) ArrayList is having 40000+ elements.
3) There are 99% read operations and only 1% write operations.
4) There will always be separate threads for read and write operations.
5) If i use Synchronized blocks to write data, it becomes a major bottleneck.

Please suggest that how I can optimize code in above situation. is there any Collection which supports such kind of high read operation with good performance.
