In reply to Frank.

With the original SSD drives on the market, this was a very important concern. We told SAS users to monitor the IO throughput on their new SSD drives and when they started seeing a significant performance degradation to remove all data from the SSD drive and reformat it and the copy all the data back. Because of this, SAS took awhile to fully endorse the SSD drives.

However, with today's SSD drives, we do not see that performance degradation with writes like we did 1-2 years ago.

Hope this helps. Please let me know if you have additional questions or concerns.
