INOV8 Secure Digital High Capacity Cards (SDHC)

SDHC (Secure Digital High-Capacity) is a new Flash memory card based on the SDA (Secure Digital Association) 2.00 specification. SDHC provides removable memory storage for compatible digital devices, including cameras, camcorders, PDAs, MP3 players and more.

Features:-

Fully compatible with the SD 2.0 standard
Original NAND flash chip
Supports error correcting code (ECC) to detect and correct errors
Mechanical write protection switch
Operating voltage: 2.7V - 3.6V
Operating temperature: -25°C (-13°F) to 85°C (185°F)
Durability: 10000 insertion / removal cycles
Lifetime warranty
Dimensions (W x H x D): 24 x 32 x 2.1mm
Weight: 2g

SDHC cards are similar shape and size to standard SD cards, but will only work in the SDHC compatible devices (Please check for the SDHC on your device packaging). SDHC cards have been designed with reliability and durability in mind, ideal for storing large amounts of images, movie files and music.

SDHC cards fall into 1 of 3 categories, Class 2, Class 4 and Class 6. The Class of the card determines the minimum sustained write speed to the card in megabytes. Please see below.

Class 6 = 6MB/sec

Class 4 = 4MB/sec

Class 2 = 2MB/sec

Specs

The growing demand for high-capacity flash memory springs partially from the increasing use of high-definition video and high-resolution digital photography. SDHC cards meet the challenge of these demanding products not only by providing ample storage but also by introducing a new feature: classifications of data transfer speed (DTS). Consumers can get the best performance value out of their digital products by using flash memory cards that support the device\'s highest standards for data transfer speed. The SDHC specification 2.00 calls for cards to be classified according to the minimal sustained DTS as follows:

• Class 2: minimum sustained DTS of 2MB/sec
• Class 4: minimum sustained DTS of 4MB/sec
• Class 6: minimum sustained DTS of 6MB/sec

SDHC cards are classified to guarantee a specific sustained DTS. This potentially saves consumers money, as flash cards are priced not only according to capacity, but also to speed. For example, if a product\'s maximum DTS is 2MB/sec, dishing out extra cash for Class 4 or Class 6 SDHC cards would be a waste of money. Conversely, devices that can utilize the 4MB/sec or 6MB/sec DTR will perform significantly better with Class 4 or Class 6 SDHC cards, respectively.

Secure Digital was forced to create a new specification for SDHC cards when the previous specification topped out at a capacity of 2GB. This occurred previously when SD cards hit the 512MB wall. The new 2.00 specification should last a bit longer, as it allows SDHC cards to reach a maximum capacity of 32GB. Secure Digital is so-named because of its ability to protect copyright content through digital rights management or DRM. Because of this, it is a favored flash memory format in the audiovisual industry.
