The SD and SDHC memory card is a highly secure stamp-sized flash memory card, which can be used in a variety of digital products: digital music players, cellular phones, handheld PCs, digital cameras, digital video camcorders, smart phones, car navigation systems and electronic books.

To support the higher capacity needs, SD cards are now requiring a different design. The new SD 2.0 specifications - which supports 4GB and up - is called Secure Digital High Capacity (SDHC). The SD Association has created and defined 3 speed classes to help you identify speed and performance capabilities/minimum requirements of SDHC cards and their SDHC host products.

Cards address data (read and write) at numerous speeds. Many factors impede this performance. SDHC guarantees a minimum read and write speed necessary to handle recording high quality video and audio. The maximum card speed may vary, but you can always depend on SDHC cards to meet your SDHC host product's high quality performance requirements.

Because SDHC works differently (supports the new higher capacity cards) this new card format is not backwards compatible with legacy SD format host devices.

 Reasonable speed, but a great price.

I bought mine at 24.99 and I'm glad I did, it's crazy how low flash prices have gotten. A year ago it cost as much to buy a 16GB SD card.

As the other reviewer has noted, this appears to be a Class 4, the one I received is like the picture and denotes Class 4 on its exterior.

As always, it's good to test SD cards for fakes with a utility like h2testw, and the results prove that it is not fake and indeed a Class 4 card:

Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 4.46 MByte/s
Reading speed: 9.53 MByte/s
H2testw v1.4

 Excellent Price

Got this for twelve quid total bargain for 32GB capacity. The card isn't the quickest in the world but if your just using it for photos this won't be an issue.

 Excellent SD card

When I ordered two mine were both Class 4 cards so I think the description might be out of date or I just got lucky.
Works great in my laptop computer!

 Works great with my Panasonic HD Camcorder

This works great with my Panasonic HD Camcorder. I bought this here for 17.99, but then Play put the price up to 24.99!
