one big card or many small cards

On my 5D Mark III's, I "Record Separately" RAW to both CF and the SD. My SD is a back up of the CF. No need to bring a laptop if not needed.

Thanks for all your help

Got two of these

chances of a big card corrupting is much lower than LOSING multiple smaller cards.

Dual 128GB's + dual card slots, that's all I need.


I think the fear of large drives is probably unwarranted. Servers can have drives of 16 terabytes or more..... sounds big, but try splitting up hundreds of terabytes into smaller drives, the complexity would drive you mad.

thanks for your help.

Will the card support full HD video 1920*1080 at 25 FPS on canon t6?

well I run one UHS-ii, expensive card, but my other is a transcend 128GB, 90/mbps, and it supports 4K 100mbit and 1080p 120fps, so yeah it should work on the t6.

Got it on sale many years back for $30

1920x1080 HD video from T6 only need Class10 card, that more less mean sustained write of 10MB/s. it is very low requirement, even Sandisk Ultra card will do that just fine.

I think this is probably right.

I use a variety of 16, 32, 64 and 128 GB cards. My strategy is that each camera has its own card, with its speed and size suited to the camera. The size of the card is such that it never needs to be changed in the field - because IMO changing cards in the field is risky, probably much more risky than the chance that the card will corrupt. The pics are downloaded after each shooting session, at home or in the hotel, usually in the evening. The camera is turned off, card comes out (little door left open), pics are transferred to computer by a card reader, and card goes back into the camera.

On trips away from home I use big cards like the 128 GB. Each day the new pics are copied to the laptop. The pics are often left on the card until I get home, and that serves as a backup. But I will usually also have a portable external HD where I will do backups of the laptop, after culling. Plus I usually do a dump of all the files on the card to the HD, just in case I change my mind about a file I culled.

Works for me, never had a problem with corruption.

That’s my philosophy too. I know I’d have lost more cards than I’ve ever had corrupted images. Even then, I’ve never had an entire card corrupt, just a few random images here and there. All of my cameras take dual cards, so I use either dual 64GB (7D2) or 128GB (A7iii & EM1.2). That’s more space than I need shooting a couple of days of softball tournaments or an all day wedding. If I’m on a trip I’ll leave all of the images on the card even after I back them up for another layer of security. I also always use authentic cards from Lexar or Sandisk, since the vast majority of my issues were way back when I first started shooting digital and cheaped out on cards by buying lower end brands.

I think most people prefer many small cards (8-16GB) over a big one (128GB+) mainly because of the cost. Those 8-16GB cards were accumulated from years of usage. Instead of retiring them and get a large card, they just keep using them. In today's card industry, larger cards are actually more reliable because manufactures do more stringent test on larger capacity cards. On the other hand, low capacity cards, like 8-16GB are mostly from reclaim memory.

That may be the case for many, but some of us who shoot sports/action actually need newer/faster cards to keep up with our 20+ MP cameras shooting at high fps. My EM1.2, for example, will shoot 60fps with full res raw files (18fps with CAF), and has even more shots already in the buffer if you shoot with ProCapture mode, so it can be very demanding on card speed. As a matter of fact, I could tell a huge difference going from Lexar 1000x UHS-II cards to Lexar 2000x UHS-II cards in the A7iii and EM1.2. I did some (unscientific) tests, and they do indeed clear the buffer roughly twice as fast, so that’s a huge boost. That also means we usually need a larger card for all of those shots, at least that’s my preference. Big fast cards are not cheap, but they do offer some tangible advantages for those who need them.

I’ll agree, if you shoot portraits, landscapes, and general family stuff then card speed isn’t nearly as important and older cards are perfectly fine as you really have no need for a really expensive card.

Small cards for me. I don't put all my eggs into one basket...too many issues can come up and ruin your entire trip if you go out on the limb with 1 card.

if you really think about it, your scenario is still an all eggs in one basket one... you only changed what is considered the basket

I have a range of cards from 2gb to 128gb, but the 128 is too big for my uses as it came with a used body not worried. Personally I use different card sizes depending on what I am doing so if I know a lot will be taken a larger card and so on. I prefer to have spares in the bag just in case something happens which has on occasion, some odd glitch as the card tested out and worked fine. In buying cards I think it is better to have a few spares, enough to cover some error making a card unusable. At the same time I feel avoiding having to do too many card swaps in the field is preferable especially with more fiddly cards like SD but as I work in urban environments I take the hitting of 30 shots left as you need coffee warning so go to a cafe and sit down and change cards then. Oh and buy good cards from trusted sources, never had trouble with a Transcend card like the Op has got.

i just got a sandisk extreme pro 16gb for testing and after a few clicks it said memory error format card and re-insert.

Bye bye Sandisk i have heard enough horror stories about their cards could be a fake as well.

Shoot to both cards if your camera permits.

My T6 canon does not support dual cards
