The way catcha tried to talk here is he has the Sandisk Ultra II 1Gb card, your 256Mb card perhaps is long out of date with the D70.
Members on this board may used them at their first beginning when they have their D70 but after few days, they never use them again or use them as backup or spares. The most used cards which I found are 1Gb, 2Gb, 4Gb now, even with 512Mb, people just keep it in their bag.
The 256Mb cards you have are also the old type, not the Ultra II (45x or 60x) not the fast card and you didn't use them on the D70 or DSLR, then they are difference, P&S have difference speed of writing and slowisssst! in comparison with the D70 or any
modern DSLR. You may or may not experience with it when you didn't have the DSLR as yet.
Thus the D70 is only required card with maximum speed of 45x, any card with other speed (60x, 80x) higher than that won't make big difference in shooting (refer to shooting in RAW), benefits only in card reader or transfering pics from CF card to PC or perhaps storage device.
I have most of Nikon DSLRs in my hand and never ever use or have any Lexar or Sandisk in my inventory. The only cards I have and use are the Transcend, second is Astone in 45x and recently upgraded all to 80x. I didn't have any problems at all with them in the last 4 years, started with my D100.
Members on this board acquired heaps of Transcend and Astone cards for their D70 but none of many complaints about their performance, same as none of return for warranty.
People may happy to spend more monies for the expensive cards with their fancy marketing but do we need them for the D70 or the D2 series?
and it's your answer.
