Product Description
Manufacturer's Description
Secure Digital memory cards are the latest generation memory devices that offer an incredible combination of high storage capacity, fast data transfer rates, great flexibility and excellent security in a memory card about the size of a postage stamp. Based on nonvolatile memory components and encased in a protective molding, they do not require power to retain the information stored on them. Since they are based on solid-state components, they have no moving parts to skip or break down, making them highly reliable.
The SD standard provides an easy method for quickly downloading and transferring secure digital files from your computer or the Internet. By using a SD Reader it is also possible to upload files from your SD card to your computer. As the latest introduction in the competitive Flash Memory form factor, SD is an increasingly popular format for leading manufacturers of digital devices like, MP3 players, digital cameras and PDAs. Because of its small foot print SD makes it easy for device manufacturers to integrate expansion capability into ever smaller devices.

cheap and cheerful,

This review is from: Viking 256MB Secure Digital Card (MLC) (Accessory)
I bought this card for use with a Casio Exilim Z4 digital camera and it has worked flawlessly. It worked as soon as it was inserted and I have never lost a photo on it, even when full. It is a very cheap card and does not operate as fast as more expensive cards, taking about 15 seconds to write a 60 second movie to the card. Deleting photos and videos is fast enough for most users, however it can take almost a minute to delete an entire card - very slow compared to others.The card is very cheap for the capacity on offer and has been completely reliable in my experience. If you want a faster card I would recommend the Kodak, but if you don't care or funds don't stretch, this'll do nicely.

I have just purchased one of these cards for use in my Mustek DV400.It seems to work fine with MP3 files,Photos & Films.Therefore I can't complain.My only gripe is with uploading film footage that's around the hour mark in length as it can be a bit ssslllooowww,but in every other aspect O.K.

Reliable and Low Priced but Slow Write Time,
By A Customer
This review is from: Viking 256MB Secure Digital Card (MLC) (Accessory)
I bought this Viking card as a replacement for a SanDisk SD card of the same capacity. So far it's been very reliable in my PDA. My SanDisk card often failed to read and write large files. What promted me to eventually change it though was when I tried to upgrade my car navigation software (which I store entirely on the SD card) and it started crashing all the time and certain parts of the software refused to work.The Viking card says on the back that it is Japanese made whereas my SanDisk card says it is Chinese made. I have read several times on the web that China sourced SD cards have much poorer production quality control that the Japanese cards hence making them more unreliable. I don't know how true that is though. SD cards seem to be quite slow in general. I guess this is because they use a serial interface rather than parallel interface as in compact flash. This keeps the physical size of card down but has the tradeoff that you can't transfer as much information as once. Annecdotally, compact flash is at least 4x faster than SD although I don't have a CF card to test it and there are different versions of both standards. Also you should note that most types of memory cards are generally slower at writing to the card than reading from it. I compared the read/write times of my Viking SD card with my SanDisk card. The Viking card has the same read speed as the SanDisk card however it only has about half the write speed. This is probably why reviews of this card vary so much i.e. some people think it's great and other people think it stinks. I use this card primarily for car navigation which is a read heavy application. You write the navigation software to the card once and read it back ever more. It is very rare that I actually alter the contents of the card. So for me the write speed is completely irrelevant. Most of the people who criticise this card are probably using it in digital cameras. This is because digital photography is a write heavy application i.e. you're constantly writing pictures to the card. If the card is slow at writing then that has an impact on you because you have to wait for the write operation to complete before you can take another picture. Conclusion: Reliable card but slow write time. Fine for PDAs and MP3 players but try another type for digital cameras.
