No Drives cannot be downgraded , the only option if you have issues ? is to RMA the Drive , the down side is Samsung WILL NOT Cross-Ship , so you system will be down while the swap is done.
The most common issue is pauses , this started in Dec with the 3B6 FW , 4B6 FW was released about 2 months ago as a Fix but some are still having Issues.
