Why do Nexus 7 tablet was left without a memory card?

Before the release of the Tablet PC Google Nexus 7 in the network are discussed in full advantages and disadvantages of device. Perhaps the main argument used by critics of the device - a lack of support for memory cards. The most popular version of this decision is an attempt to impose on users of cloud services Google, such as Google Drive, or Google Music. I think that without this not done, but the reason why the Nexus 7 was left without a memory card is more complicated than it seems at first glance . Dan Morrill (Dan Morrill), Android-engineer at Google, said on this subject: "We are tired of watching, as manufacturers provide a large amount of memory for media at the time, as users do not have enough space to store applications and data. Our approach is to combine all in one, which is much more convenient. " While Google is prezhdnemu supports removable media in the operating system Android, the corporation relies on a large block of storage (in the Galaxy Nexus, for example, and now the Nexus 7), which users can use to save all information - from the media and documents to applications. This strategy has several additional benefits. The first advantage of interest, mostly tech-savvy users. It consists in the fact that the device can use the file system type ext (Extended File System, extended file system) instead of a combination of ext and FAT (File Allocation Table, File Allocation Table). The new method is faster and safer to work with data stored on the device, especially a personal nature. A journaling file system reduces the number of system errors and keep its integrity in case of trouble. Another advantage is that the hosting machine (connect to your computer ustryostva) can not change the file system, since it does not block access to files. Instead, for debugging a pseudo-SD card using a proxy FUSE (Filesystem in Userspace, the file system in user space). This means you can avoid errors due to incorrect debugging the phone and the device will be able to maintain access to all data, even when connected to a computer. Of course, Google - not a charitable organization and one of the reasons for refusal of an SD-card - a popularization of cloud services corporation. But you're still free to use third-party "cloud", for example, Dropbox or Yandeks.Disk, so that did not look too much dirty trick in the intentions of the company's Mountain View. 

In 2012, the card will be faster

The new high-speed memory card format is called XQD and can transfer up to 125 MB per second. The new format approved association CFA (CompactFlash Association).

XQD will replace the cards CompactFlash (CF), which are mainly used in professional photo and video equipment. The advantage of the new cards will be durable and writing speed. Now the fastest CF card today, this figure does not exceed 100 MB per second.

Size of the card will make XQD 38.5 by 29.8 by 3.8 mm, which means it will be a little more than card SD. The card is used an interface similar to bus PCI Express.

The new card format supported by manufacturers of photographic equipment, Canon and Nikon. Map XQD first show at the exhibition CP +, which will be held in February in Japan Yokohama. License XQD Association CFA collected in 2012.

Format CF card was developed by SanDisk in 1994. To date, standard CF (specification 6.0) admits a maximum theoretical data transfer rate up to 167 MB per second.
