Don't buy either card. They are grossly overpriced. Don't bother with something as small as 8gb if you intend to shoot in raw mode. If in jpeg mode, 8gb is plenty but should be no more than 10 dollars. There is no technical reason to reformat after each use. There are practical reasons however. A card should be reliable up to and including becoming full. However, the longer it is used without reformatting, the greater the chance of a file system error being introduced due to incomplete writes (user error most likely). Second, by reformatting frequently you know for sure how much storage you have. Faster is better.

I reformat after I have my pix copied to at least two different hard drives.

if you have questions, i would highly recommend that you talk to the boys at the camera company and let them explain things in easy to understand camera talk when it comes to the memory cards....AND marlene is right with reformatting. i reformat every time my photos come off of my camera and this is based on what i was told when my photos got SCREWED up just once from not reformatting often enough. since then i have never had a problem. reformatting takes 3 seconds vs the one second it takes to "delete all." i don't want to sound harsh, but i also don't anyone to ever lose any photos like i did just because of not reformatting.
But the boys at the Camera shop will probably try to sell one of their $50 cards which was the original question, are they worth it? The responses have been no way, they are overpriced. But maybe I shouldn't say that about our meetup sponsor.
I've taken over 10,000 photos without ever losing one to a bad memory card and rarely reformat. I'm sorry to hear you lost photos due to a bad card, but I question the source as to who told you that your lost photos were due to not reformatting enough. I think they may be mistaken.
Another reason I don't reformat is I often have a couple favorite photos on my cards that I want to keep "protected" so they don't get deleted during "delete all". They would get deleted in a reformat.

EXCELLENT advice from Mr. Cable of Lexar. I use SanDisk Extreme SDfHC cards, I've been using SanDisk cards since I read very good reviews on them back in the early 2000s. I have never plugged any of my cameras into the PC, always use a built in card reader on the PCs I build, or on the included reader on my laptops.
SanDisk used to include RescuePRO with their professional cards. (http://kb.sandisk.com...­)

I have recovered images that were deleted using this software.

If you need to recover data/images from a hard drive RescuePRO will NOT work, it is designed for flash drives, I'm guessing it will also work with Solid State Disks as well.

I have recovered data from a hard disk I accidentally formatted using Recuva: http://www.piriform.c...­

I always format my card in camera after I've saved the images to my two hard disks (RAID 1) and a third external disk. I'm fortunate I've never lost data from my flash cards.

I bought two of these a little over 1 year ago, they were $4.00 more each back then. http://www.newegg.com...­

I would be happy to give a presentation on backup, RAID levels, and the like at a meeting.

Perry, we are always looking for member presentations. I will check with the other co-organizers to see when we have openings.

In Alfredo's video post I didn't hear Cable say anything about how often to format memory cards. I did a web search and found many opinions. Some say format often, some say formatting often does nothing but shorten a card's life, some say format occasionally. I'm still not going to format mine often but it's up to each of us, of course.

"Generally speaking, you don't need to format an SD Card. But it's always a good idea to format any flash memory card ocassionally...You shouldn't format flash memory devices too often either. Unlike magnetic media, flash memory can only be written to a finite number of times (the actual number is in the millions, but it's still finite.) Formatting does a lot of writting, so everytime you format a flash memory device, you're getting that much closer to the point where you can't write to it anymore."

http://www.digicamhel...­
"A memory card should be formatted several times a year, particularly if its performance seems sluggish. Format more often if your camera is used frequently."

http://www.flickr.com...­
"Reformatting just writes over the index at the beginning of the card that tells the camera and your computer where the files are. It doesn't actually write the entire card. So, there's really no disadvantage of reformatting the cards after every use. Most flash memory these days is speced at having a life of between 10,000 and 100,000 writes. Better cards use wear leveling to spread the writes evenly across the cells so you don't wear out some of the card faster. The bottom line is that the cards will usually outlast your use for them."

Nikon user manual:
"Memory cards need occasional maintenance, too. Every Nikon digital camera offers an in-camera format option. Formatting the card in-camera not only deletes the pictures, it creates a new directory on the card. This can help to avoid problems that might prevent the card from being read by your computer. Some people format after each download, once the photos are safely transferred to the computer. Others choose to do it once a month. The important thing is to do it regularly."

John Cavan reply:
"Nikon is covering their rear end, there's no technical reason for this but lets them out if you have an issue with a card and contact them. Let me put it this way, the most likely source of corruption would be your camera."
