Memory Cards For Cameras And The Day Of SDHC VS SDXC

By Rick Newman


The race between data storage has units has made the product more compact and handy. This has brought a new format of data storage to the world of computers and computer systems. This has made the world a little easier to deal with but the public must always look at SDHC vs SDXC and decide which is the best.

Speaking of memory cards for cameras, the SD family of storage devices have many different formats that determine what is the best. The computer system can also determine what would be the most logical way of being able to store data. The range goes from more information storage to a different way of saving the information. This can be a very important detail for those who want to store information with a particular format.

The SDHC format stands for secure digital high capacity which is an expanded version of the standard storage devices known as the SD family. The storage level is up to thirty-two gigabytes of memory. This format carries the same format at the older SD card types. The device uses sector addressing and not the byte addressing as the standard is for older types of storage units of this class.

Byte addressing has a full capacity of four gigs when saving information. The method known to the SD family as sector addressing is up to two TB for data saving. It is said that the SDHC can store up to 32 gb of information. It is a good storage media but can't be used in older computer systems that use the SD 1.0 setup.

The SDXC saw the day of light in the year 2009. The method of storage known as secure digital extended capacity was brought into the world at the Consumer Electronics Show or CES. SDHC has been created to go over 32 GB of storage, but has been purposely set at 32 GB. The limitations are set by the 2.0 format. SDXC cards are labeled with a 3.0 classification with SD 4.0 for later more updated SD cards in 2011.

The speeds set for SDXCs with a SD 3.0 set up was introduced as 832 Mbit per second which is called UHS104 speeds. The SD 4.0 is setup to have transfer rates of 2.4 gbits per second. The official format for the SDXC is the exFAT file system. Other file systems such NTFS and others can be used on the storage unit is need be. This is one of the benefits of this device.

1999 brought the SD card out to the front door when SanDisk, Matsushita, and Toshiba decided to develop the market for the SD card. The SD card was created by MMC or the MultiMediaCard. The storage device was setup to compete with Sony Memory Stick which was put out the following year which focused on the MagicGate DRM

The main point focused on SDHC vs SDXC depends on what format and computer the person has in their possession. The good thing about the SDXC model is that it can store more than the SDHC. This has become one of the main points, the ability to store more data to save the items that people need. The choice depends on the format and what is trying to be saved.
