Re: sony sxs 64gb cards

Les, unless I'm misunderstanding the term wrangling applied to memory cards, isn't this what I've addressed?

This seemed to indicate you thought it was related to DSLRs.

Les, as you see, it was you who first introduced DSLRs into this thread, not me.

That was the name of the tutorial where the issue of card size philosophy was presented by Shane Hurlbut that I was summarizing for you.

Re: sony sxs 64gb cards

I use Sony 64GB G1A SxS cards on my F3 and these have been flowless.

My 2 cents.

Maybe I'm cynical but it strikes me as more of a marketing ploy to justify suddenly having to halve the cost of SXS media in response to Panasonic releasing cheaper P2 cards.
I understand the cynicism but the reason behind both Sony's and P2 E's cheaper price is due to the use of MLC NAND Flash which has a much lower number of write cycles than the expensive SLC flash. WIth the 32nm flash chips, MLC has about 10,000 write cycles whereas SLC has 100,000 - this explains the 1/10 life cycle. However, with the newer 25nm flash, the # of write cycles has decreased to ~8,000. This reduced write cycles is a major problem as the size of flash chips decreases. With the next size reduction (20 or 22nm), the # of write cycles will decrease again.

The only way to see significant reductions in the price of NAND chips is by size reduction. Thus, I do not expect a significant reduction in SxS prices in the next 5 years.
