Are two cards better than one? SDHC

I would prefer to have a couple of smaller cards than one wopping great big one.

Its only an "eggs in one basket" argument.

In this day and age is it still valid, in the 4 and 8 gig range?

 

Eggs in two baskets are almost always better than one :-)

Rob, I have always subscribed to your theory. 4GB has been my standard size. There are occasions when I fill two of them on a shoot using the M8, but not too often. Contemplating the M9 (:eek: ) I am wondering if I should 'upgrade' to 8GB. OTOH. Swapping out a 4gb is no hassle after years of changing film. :p I will stick with the idea of "many baskets of eggs" as basically sound with no perceivable disadvantages.

Erl-

If you barely fill up a 4 GB SD card in a day, what real difference would it make if you had an 8 or even 16 GB SD card in your camera as long as you download at the end of the day?

Personally, I have been using 32GB cards for the past several months with my M8 & am delighted to be free of worrying about changing the card at the usual inopportune moment. I do download every evening to be on the safe side.

Now, if only Leica could make a nuclear battery..... :D:D:D

Albert your point is good. My real concern is, I guess, more when I travel. At such times I tend to fill all cards progressively as I travel. I don't carry a laptop for 'compactness' but do have a JOBO 40GB GigaVuPro for dumping. In these situations, I don't like to wipe a card, even if I have downloaded to the GigaVu for security reasons. The crunch is IF I lose or destroy a card, I like to think I have lost less if the card is a smaller one. Also cards do fail, abeit rarely. Just sticking with the egg basket theory. I hope I don't ever have to prove this theory but if it ever comes into play I will be somewhat relieved.

 

As a 'filmic' parallel. Years ago, I shot a stage show on film. 10 rolls were exposed and I processed them in two separate batch, deliberately selecting them randomly. As it transpired, I made a mistake in processing the first batch (dialled in 1.4minutes insted of 14 minutes on the colour develover! :eek: ) Result: 5 rolls screwed, but I still had 5 rolls randomly spread through the show so that I could still produce a full spread from the show. Lesson: I always avoid putting all my eggs in one basket. At least not the baskets I use.

Cannot argue with that but consider the following: when travelling, dump everything into the JOBO every night and still keep the full card in a GEPE waterproof holder. Bring multiple cards (16 0r 32 GB) and never reformat until safe at home!:)

 

Probably I did not express myself clearly Albert but that is what I more or less do. Belt and braces stuff. With M9 and larger file sizes, I will need to revisit card sizes and quantities for my next travel, probably to India now that I have canceled out of the Malta 'One Chalenge'. Techniques always evolving. Keeps us alert. ;)

I limit mine to 2Gb.

As I've mentioned before I work for one of Canada's largest pro photo retailers.

One of my jobs here is data recovery from corrupt cards.

I live in a city of 1/2 million and I do about 30 card recoverys a week. There are two other major retailer in the city so I'd imagine they do the same.

30 a week...way more faulty cards than we ever received faulty film/processing.

I'm pretty good at what I do...I have about a 75% success rate, which means that about 7 times a week I tell people...'sorry, your images are gone' (they can always send them away to have the cards physically deconstructed and the data purged...but at $400 a pop not many are willing.

Doesn't seem to matter the card brand, and the cheap no-names seem to be just as reliable as the more expensive hi-performance cards.

The people who loose 8Gb are usually more upset than the 1 and 2Gb crowd.

One thing...most of the cards that are easily recoverable...the problem can usually be traced to asking the owner how often they format (as opposed to delete).

The answer is usually "what does format mean?"

I too limit my cards to 2Mb, I have two friends who have had card coruption problems on returning home from holidays of a life time. Both had all their images on one large card. holiday memories lost forever.

The not all eggs in one basket saying is certainly true.
