MSP430 typical programming time... 4-wire? 2-wire?

Very preliminary design stage.  I have no previous MSP430 experience, but I think it will be the right chip for our project.  I'm trying to decide if I should design it with a 4-wire programming interface or the 2-wire.  I understand 2-wire takes longer, but I've found no mention of actual times other than "10 times slower".

Is it a matter of 2 seconds vs. 0.2 seconds?  or 2 seconds vs 20 seconds?  or 20 seconds vs 200 seconds?

I would like to save the board space and use 2-wire, but not if it takes a considerable time to program.  I'm not talking about prototype quantities, but rather 1000+ production run quantities.

So could you please give me some idea of expected programming times for 4 wire vs 2 wire?  Thank you.

    Speed for TI MSP-FET can be found inside www.ti.com/lit/slau278

    Speed for Elprotronic / TI MSP-GANG can be found inside http://www.ti.com/lit/pdf/slau358

    Speed for Elprotronic tools can be download on this page https://www.elprotronic.com/productdata (Benchmarks for FlashPro-430  MSP-Benchmarks.pdf)

    However, fastest tool for MSP430 devices is my SBW+ (MSP-GANG like)  flasher, that can write up to 48 KByte/s for 2xx devices, and up to 200 KByte/s for 5xx devices. It is standard SBW interface extended by one I/O line.

    Hello Soli,
    The Image you have mentioned in post looks a cool tool... May I know exactly which tool it is and how one can buy? I know MSP-GANG but this board looks different.

    It is standalone flasher (not debugger), not compatible with TI software. Only CLI (open source) executable is needed on OS side, no dll / driver / installation, except (unsigned) inf file for Windows. Development is documented on 43oh topic...

    On previous picture is version without fuse blow for 2xx family. Final version with fuse blow for 2xx family should be similar to this one...

    Here is detailed benchmark...

    Flash / FRAM / RAM Quick Read (2) 9.5 19.1 38.2
    Flash / FRAM / RAM Quick Verify (2) 9.1 18.2 36.3

    (1) Writing rate is not fixed. It is calculated for each target device.
    (2)Standard SBW function, without using PIO line (SBW+).
