Old thread but here goes anyways,

I have a 16Gb Sandisk Extreme III ($50)
a 1Gb MS ProDuo (this stays in the camera because my dumb ass leaves the CF card in the card reader at least every month or so) ($20)

I keep one big CF card that way I know with certainty that I have room for ~1000 raw format shots. I have never needed more. If I am on vacation I shoot Jpeg or at least cRAW which give me 4000 or 1800 shots respectively.

The MS card in the cam is an insurance policy so I never end up completely card less.
There is no problem in the world that can not be solved with the proper application of explosives.

Why don't you hold a poll to see if a poll is justified.

IAC, I know of nobody who has had a CF failure - except myself with a brand new card that died after less than 100 shots.

I think if a card survives the first 1000 shots, it is essentially good for life (following the bathtub curve for electronics failures and the fact that long before we get near the end of life of the card, it will end up sitting in the bottom of the bag as an emergency backup as we will have moved on to larger-cap/faster cards within a couple/few years.)

Other reasons to avoid several cards are logistical: you are less likely to accidentally format a card that you haven't offloaded yet (which, by the way is recoverable if you have the s/w tool for it).

I do know some people who always prefer several smaller cards over fewer large cards. I'm just not in that camp.

1-Have you ever had a card failure? 1

2-What size card resides in the camera? 16GB or 8 GB

3-Do you download with a card reader or the camera tethered? 90%: card reader.

4-Do you delete all pics or reformat after downloading? 75%: re-format; 25% delete by computer/card reader (Mac OS X).

5-How many frames has the card seen? The card that died had less than 100 frames shot. It was a classic electronics declining bathtub curve failure. Other cards in the past (1 or 2 GB) have had over 10,000 frames shot resulting in about 50 overwrite cycles*.

*Note that when you delete images from a card, new writes to the card occur in older cleared areas. This is to spread the 'death' of the card over the entire memory. A bit of the cards memory is reserved to track where the next write area is.

1-Have you ever had a card failure? No. A trade show rep from a tier-1 maker suggested 80% of failures are due to the user taking the card out without logically / electronically ejecting it. This can put a controller in a transient state it does not on its own know how to recover from, and/or sets a "time bomb" when the related memory segment is accessed later.

2-What size card resides in the camera? Sandisk E-IV Ducatti edition (45MBps) 8Gb. I have 2 of these. Also Memory Stick 32GB. I tend to get the largest cards available after 1st price drop, then skip 2-3 years. It's almost time to trade up from the Ducati's to the faster 64GB crop of CF's. I do not believe in having more than 2 cards per camera other than for historical reason or special workflow requirements, simply because, as long as you deal with tier-1 manufacturers (Sandisk, Lexar, and such), the risk of loss of any given picture is far greater due to human error, physical loss or mishandling, than electronic failure.

3-Do you download with a card reader or the camera tethered? Reader

4-Do you delete all pics or reformat after downloading? Reformat

5-How many frames haVE the cardS seen? ~ 20000

Only one card annoyance once: a thin blue line on all the pictures on one CF card. I rinsed its connector with ethanol, dried it 2 days and it's still working 5 years later.

Last monday I unpacked a new 4GB Sandisk SDHC when the mailman was at the door. When I returned, the memory card magically had vanished. This morning my dog laid an "egg"... It's still working. Fortunately she didn't chew.

I've never had a card fail.

I always reformat in the camera, always right before I use it (I have 2 cards I cycle through).

I like 4 GB cards because they are about equal to a DVD (4.7 GB) so I can back up one card to one DVD. Also If I use bigger cards, it's just too many photos in one place if I happen to take the card to the photo kiosk.

1-Have you ever had a card failure? Yes

2-What size card resides in the camera? 2 or 4GB in A100 2, 4 or 8GB in A850.

3-Do you download with a card reader or the camera tethered? Card reader until card reader/drive got too small. Not via tether.

4-Do you delete all pics or reformat after downloading? Delete all

5-How many frames has the card seen? Over 1,000 for the 2GB cards, few hundred (>500) for the 4GBs and 1 of the 8GBs.


My card inventory consists of (in approximate order of age)

2GB RiData Pro 150x card 3 years
2GB Sandisk Ultra II 3 years
2 x 2GB SanDisk 3 years

2 x 4GB Kingston Elite Pro 133X 1 year?

8GB Sandisk Ultra 30 MB/s 5 months

8GB Kingston 1 month

Only failure has been the 8GB Kingston that had a weird issue. If I hooked up the camera to a PC and transferred the pix files, the camera would no longer recoqnise the card (will become unusable and not formattable) and it may or may nt have been recoqnized by the PC. This was within a week of getting it. I sent the card to Kingston via FedEx and received a new one (works fine so far) since.
