We are using Windows 2012 server and the fusionIO VLS version 3.2.2 drivers that have native TRIM support. I was not expecting such a big drop in performance given the trip support.
I have not prior experience with Enterprise Flash storage card so I am wondering how you restored the performance to a prior "preconditioning state" ? Would running the Fusion fio-sure-erase do the trick or is it just a matter of leting the device site idle for garbage collection to work and improve write performance.

Before runs we use the fio-format command which does a secure erase of the drive/controllers specified. I believe fio-sure-erase is a step beyond that that would probably put additional wear on the drive and more towards a security wipe.
Thank you Kevin, I tried different things yesterday to restore the performance, I started with just re-formating the disk at the NTFS level and issuing a TRIM free space cmd, that improved the performance but not the original values I 1st saw. I then tried the fio-format and that did the job.
I have another question, while our indexing workload is running I'd like to capture a graph similar to the ones you create in your enterprise benchmarks that plot the IOPS over time showing the precondition curve. I was wondering how your captured the data; I guess you generate a steady load using iometer then capture the data using Perfmon recording the Physical Disk:Writes/sec then plotting it out in excel ?.
