Re: Sony RX10 user experience thread

Thank you Dave, for all that information. They will be used for video, using the XAVCS format.

Thanks.

Re: Sony RX10 user experience thread

I use the SanDisk Extreme Pro, 95MB/s U3 64B. Yeah they are expensive but I think this is a minimum one needs for the RX10 and XAVCs

I have no problems with this card.

Re: Sony RX10 user experience thread

Thanks Simon, I have two of those cards too but just wondered about the non pro version.
They also are Class 10 U3 Memory.

Thank you again.

Re: Sony RX10 user experience thread

Memory has become QUITE confusing, no doubt to the ever increasing speed demands. In some cases I have U1 cards that are no doubt "fast enough" (95MB/s), but since they aren't U3, the camera says, "NO"...

Most of the time you can operate a given camera at a lower quality with lesser cards in a pinch, but of course we want to get the most performance at the highest quality our of our gear... and not have to buy new memory every couple months...


Here's a sort of "quick and dirty" breakdown, at least for Sony cameras....

SDXC required for XAVCS, NOT SDHC (I've seen SDXC I and SDXC II on some branding, apparently for U1 vs. U3, but not sure it's anything other than marketing)

SDXC seems to be ONLY 64G cards and above, although I've seen some 32G cards on ebay... may or may not be legit cards, since memory is a highly knocked off item... I'm sure there is "demand" for smaller capacity cards, but I'd rather stick to the 64G or larger...

"Class" means almost nothing, as you NEED Class 10 for pretty much anything, and a card that meets Class 10 minimums can still be very slow (around 10MB/s from what I saw when testing...) and well below a usable spec for higher bitrates...

U3 is required vs. U1 for the latest higher bitrate recording modes.

It seems like 95MB/sec is about the "cutoff" transfer rate for U3, that 60MB/s card you linked to is the lowest I've seen while looking for "U3" rated cards.

SO when memory shopping...

SDXC, U3, 64GB or greater capacity, and as much speed as you want to afford...

Are these not a bit overkill for the rx10 XAVC? I use this card to record Lossless CinemaDNG RAW from my pocket cam.

Re: Sony RX10 user experience thread

I get the fastest I can afford just to speed up transfer after a long day of shooting.

Thank you Dave for that detailed answer, your right, it can be confusing, at least it is for me.

You summed it up well :)

Thanks.

Re: Sony RX10 user experience thread

Yeah Noa, it's overkill but that's all I could purchase at the time to run the RX10.
Cheers
