Summary: The first three months it worked great, then died!
Review: I really wanted to give this unit a good review because I really liked having the 512 megs available. I've owned this card for the last 5 months and have been going back and forth with Viking to get it replaced. They are very efficient at giving a replacement but I have recieved defective replacement units twice so far and have been without it's use for almost two months. I paid twice what it is today which doesn't bother me (technology speed). The replacements have not accepted any data beyond 58 meg and then crashed, no matter which computer, which CF reader, My laptop or PDA, it doesn't work and now I am frustrated. All my 256 meg Sandisk, Mr Flash and Kingston work fine. If you want a reliable CF card I think you may want to look elsewhere.

Summary: Not as cheap as you think, but still a good deal.
Review: DPReview gives good scores to this card for write speed, and phenominal scores for read speed. However, be careful with the rebate... Make sure to save copies of all of your rebate info, and call to complain within the allowed time if your rebate does not arrive. But still, even without the rebate, this is a great price for almost half a gig of CompactFlash space.

Review: Currently I own two Viking 512 MG flash cards. It works great with my Nikon D100 camera. I'm probably going to buy a third.

Summary: Olympus C-5050 Viking "CARD ERROR"
Review: I bought the Viking 512MB at a fair price (with manufac. rebate), but received "CARD ERROR" message on first use with my Olympus C-5050. This occured in 3 or 150 images taken at SHQ resolution (2.5 to 3.0 megabyte files). I like price, but now I am afraid to take this card on vacation for fear of corrupt images. I am planning to contact the manufacturer for a replacement.

Summary: Card itself is good, Viking are Traitors
Review: The card itself is a winner. Viking however lies about the country of origin. The big "MADE IN USA" sticker on the back is a lie, this card is made in Japan by Tohsiba. It's not assembled or made here.

Summary: Not as fast as Lexar in the Nikon 4300
Review: I compared this card with the Lexar 8x, and when using the Viking in the Nikon 4300 it takes longer to startup, record images, and recover when the battery is low.

Summary: viking 512 card works in minolta 7hi
Review: I tried several cards before this that had problems in my new minolta 7hi. (transcend 25x and ridata 20x both 512 cf cards--both problematic). This one worked right out of it's plastic sleeve, no formatting necessary. it writes a raw file at about 15.6 seconds. pretty fast huh? Amazon was a good supplier too.

Summary: Massive capacity and cheap to!
Review: I've been using this 512mb card for the past 3 weeks and really love it. At hi-res my camera (Fuji Finepix S602 Zoom) can shoot 400 pictures with minimal read/write latency. For the price I paid, [$$$]- including shipping) this memory is a great storage investment. Add a PCI adapter card and you have an instant portable data drive. There may me faster memory out there, but the price to performance ratio on this is absolutely astounding. It's much better than I hoped for.

Summary: Huge
Review: There is nothing like being able to hold over 400 pictures on my Kodak 4900 on the highest resolution setting. Should last most people through an average vacation.
