Thanks again for the advice. Looks like the M4 it is then!

BTW - a question about firmware...

Say there have been four firmware updates for SSD product - A, B C and D.

If your drive is on firmware A - can you go direct and flash firmware D to it, or are you best following the cycle of A to B, B to C and then C to D?

I know some products you can go direct from A to D as D will contain the code from A, B and C as well as the D updates....others are bit picky and want the full cycle...
