Buffered memory is used in systems that require a large number of DIMMs. So I agree with danb35, makes no difference for FreeNAS all else being equal. If you need more than 2 dimm slots per memory channel, the board will probably require buffered dimms. It's rare (these days) that a board would support both buffered (registered) and unbuffered.

Apr 19, 2002 Fully Buffered DIMM - Wikipedia Fully Buffered DIMM (or FB-DIMM) is a memory technology that can be used to increase reliability and density of memory systems.Conventionally, data lines from the memory controller have to be connected to data lines in every DRAM module, i.e. via multidrop buses.As the memory width increases together with the access speed, the signal degrades at the interface between the bus and the device. PHP: Buffered and Unbuffered queries - Manual Buffered and Unbuffered queries. Queries are using the buffered mode by default. This means that query results are immediately transferred from the MySQL Server to PHP and then are kept in the memory of the PHP process. This allows additional operations like counting the number of rows, and moving (seeking) the current result pointer.

Similarly, buffered output streams write data to a buffer, and the native output API is called only when the buffer is full. A program can convert an unbuffered stream into a buffered stream using the wrapping idiom we've used several times now, where the unbuffered stream object is passed to the constructor for a buffered stream class.

Also known as your registered memory, it is a memory that has a register between your DRAM (a random-access memory storing each bit of data) modules and your system’s memory controller (Contains logic necessary to write and read to DRAM).
