32 GB or 64 GB SD cards?

Up to now, I've rarely shot video using our cameras. But with the improved video capabilities, I want to start mixing in some video clips with the stills when I buy a new compact/pocket camera in the next few months.

In your opinion to start off with, would it be better to buy two 32 GB SD cards to eliminate the "all the eggs in one basket" syndrome? If one memory card fails at least there's a second one.

Or one 64 GB card and trust that it won't fail?

I usually take about 250 photos per one week trips. I will be shooting JPG stills. I'll be shooting 720p video and plan to shoot just a few short video clips now and then.

Thanks,
Sky

32 GB is better even 16GB is enogh , high no.of memory leads to slower transformation data.

Didn't know 16GB cards would be enough. Thanks. BTW, what's "slower transformation data"?

Suggestion: at least three or four large capacity SD cards

Hi,

It's my experience that having half a dozen large capacity SD cards is very practical. Conversely, having just one SD card is not practical at all.

If your choice is between one 64GB card vs. two 32GB cards, I suggest the latter. Actually I suggest 1 x 32GB + 1 x 16GB + 2 x 8GB. You get the idea...

The fewer card to fiddle with, the better in my opinion. On a photo trip, your camera, lens, car, anything can fail. Why would a SD card fail? With multiple cards, there's more chance of losing or breaking them, or to format the wrong one. 16Gb would be enough for your need, but I'd still pick a 32Gb.

16GB will probably be by far enough, or one 32GB if you want to have some room to spare.

A complete misunderstanding of reality. Pay it no attention, and buy a fast card of good size.

Get 2 32GB SD cards but don't get cheap ones. Get name brand cards from a reputable dealer. I have been using Transcend cards for at least 3 years and never had one fail. Sandisk is a very reliable company also. You can't go wrong.

Re: 32 GB or 64 GB SD cards?

For the quantity of still photos and the length of videos you described, 32 GB is more than enough.

Redundancy is important. A card can fail for several reasons. Or worse yet, you remove the card from the camera to transfer photos to your computer and then forget to put the card back in the camera. Having a spare card in your camera bag will help you avoid this disaster.

Re: 32 GB or 64 GB SD cards?

I wouldn't buy any 'SD' card larger than 2 GB. Such cards are not standard.

For capacities of 4 to 32 GB, buy SDHC cards. For capacities of 64 GB or higher, buy SDXC ones. Note that you will need matching capabilities in the device(s) that will be using the cards (i.e., a 64 GB SDXC card won't work in a camera that has a SDHC slot).

Thanks All

Laith, Pangloss, Erick L, theswede, SpankydeMonkey, Z_fan and Tom_N,

Thanks all for sharing your insights.

It seems that the general consensus is that 16 GB is sufficient for my needs and 32 GB if I want to be safe. I think I'll buy two 16 GB cards in case I shoot a little more video than expected. Thanks Tom_N for reminding me that they should be SDHC cards.

Also, even if I just use one 16 GB card per trip, I'll have a spare in case Murphy strikes, or in case there's an occasion and I forgot to offload the photos from one card.

Thanks folks,
Sky

Re: 32 GB or 64 GB SD cards?

if you can manage them, then multiple smaller cards (8-16GB) have benefits over fewer bigger (32-64GB):

1) price, the current sweet spot is closer to 16 than to 64GB;

2) lifetime: as the no. of writes to any FLASH card is strictly limited, it's safer to do your own card-level "wear leveling". ( http://en.wikipedia.org/wiki/Wear_leveling )
As a rule, avoid filling any card above 3/4... leave enough spare room.

3) can use them in parallel, in multiple devices - cameras, players, phones (uSD, but you can use adapters to mini and full size SD)

Don't forget the speed grade; HD video may require Class 10 or faster.

I suppose it depends on how you shoot

Today I bought a Scandisk Extreme, class 10 with 30MB/s transfer BUT at 4GB for around £15

I use 4's and 8's simply to avoid losing loads of images in the event of a corrupt card.

I don't do much video and I don't use my camera like a machine gun - I delete a lot of shots while in the camera as I despair sitting in front of a computer facing 100's of images to process.

I shoot in RAW and find 4GB cards a good compromise at 200 shots per card.

Never heard of "wear leveling" before and that was a really interesting read! I do plan to buy cards per the manual's recommendation for speed.

Thanks,

Hi Normsmith,

Thanks for sharing your info. Regarding

  • I delete a lot of shots while in the camera as I despair sitting in front of a computer facing 100's of images to process.

If you haven't tried file tagging to delete images, maybe try the free "Faststone Image Viewer". Enable file tagging and you can go through your images full screen on your computer and press the "\" key to tag images you don't want to keep. After all of the non-keepers have been tagged, return to the browser screen, use the "select tagged images" option and delete all of the non-keepers in one shot. Makes culling images very quick and easy and viewing them full screen on the computer monitor makes decisions easier.

You can do it in reverse and tag the images you want to keep. Then use the "select all untagged images" option and delete the non-keepers that way. But I have far more keepers than non-keepers so I tag the non-keepers.

Just one free way to cull images,
