C# ThreadPool for writing to SSD disk

Question

I have a thread pool writing data to an SSD disk. (windows XP, c#) I would like to choose a pool size to optimize performance. Theoretically, should performance improve with more threads? How do SSDs handle concurrent writes? And also concurrent reads, for that matter?

Thanks!

If you need to perform random io operations, you might want to ensure you're drive is running in AHCI, as random performance with high concurrency is usually faster with AHCI than IDE (see http://benchmarkreviews.com/index.php?option=com_content&task=view&id=505&Itemid=38&limit=1&limitstart=3).

This review also shows that concurrent random reads and writes (4K-64Trd Results) are faster than when using only a single thread (4K results).
