Who s going to give me ideas! MINI SD card 25

Your memory card itself is 1G!

For a 1G memory card, in order to prevent the flash memory part from being damaged, only 512M of the 1G card is left to use, and some space will be reserved for backup during production, such as 2G flash memory in the 1GD card. When it breaks, the repair department only needs to use some technical means to activate the spare flash memory that is not broken.

But you have obviously met a profiteer, and directly activated all the space in the card, and the 1G card should be bought with 2G. In this way, once the card is damaged, I am afraid that it will be completely scrapped.

The reason why the 2G card became 1G, I think the activation technology of the profiteers is not up to par, and the activated soft switch jumped back after formatting, so it restored the original appearance of the card. Or maybe it's just that the card becomes unstable due to the forced activation of all the flash memory, and half of the flash memory is scrapped, so it becomes like this.

Personally, I think the latter is more likely, so go find him for ......Take a few more people to ......

It's your computer that's wrong.

If you change the card to many people, that's the problem of your computer, you change the neighbor's computer to try, see if it works, if it doesn't work, it is your computer installed with some kind of software and your SD card conflict, if you can't install the conflicting software, try to make a new system for the computer, but also format the C disk.

If there is a problem with the computer, completely disinfect the virus or reinstall the system!

TF cards are generally more expensive in the market, and they are used in the same way.

Compared with the current mainstream ordinary SD cards (such as SD cards used on DC or DV), the miniSD card is more compact in appearance, weighing only about 3 grams, and the volume is only, which saves 60% of the space compared with ordinary SD cards. Don't underestimate such a small form factor, it can save up to 40% of the size of digital devices. In order to produce smaller mobile phones, DVDs and other digital products.

In terms of storage capacity, mini

The SD card is not bad at all, from 32MB to 1GB in various specifications, and even several G.

SD, SanDisk has also specially launched SD riser cards, which can be used with DC, PDA and *** that now use SD cards. mini

The SD is only 37% the size of a regular SD card, but it has the same read and write performance and large capacity, and is fully compatible with standard SD cards, and can also be used as a regular SD card through the included SD adapter card.

The MiniSD card is used by the SD Association.

Established in 2003 as an ultra-slim form factor for standard SD cards, this miniSD card is specially designed for mobile** and comes with a MinSD adapter to make it compatible with all devices equipped with a standard SD card slot.

The miniSD card supports the average read/write algorithm.

The rapid popularity of SD cards paved the way.

Compared with the current mainstream SD card, the miniSD card is more compact in appearance, weighing only 30 grams, and the volume is only, which saves 60% of the space compared with the SD card, don't underestimate such a small shape, it can save 40% of the space in the volume of digital equipment. In order to produce smaller mobile phones, DVDs and other digital products. In terms of storage capacity, the miniSD card is not bad at all, from 32MB to 1GB of various specifications.

As the functions of consumer digital products become larger and larger, the demand for large-capacity memory cards is also growing, and the current capacity of 512M, 1GB and other capacities has gradually become popular, and will increase exponentially in the future. The miniSD card supports the average read/write algorithm.

The rapid popularity of SD cards paved the way.

MicroSD (formerly known as TF card) is a new ultra-small large-capacity removable memory card, the size of which is about the same as that of the most popular SD memory card on the market. , or a SIM card for a mobile phone.

1/2。You can feel free to store the shooting **, ** or video files in the TF card; It can also be connected to the computer through the SD card adapter, and the files can be copied from the computer to the card, which is very convenient for transfer, and can expand the memory capacity of dust sources such as collection at any time.

Both cards can be used as SD cards via the Adapter.

The size of the miniSD is one lap smaller than the SD card, with 11 pins.

The microSD (formerly known as the TF card) is about a quarter of the size of the SD card, with 8 pins.

That's basically the difference, the speed of both cards is about the same.

MiniSD card is more compact than the current mainstream SD card, with a weight of only 30 grams and a volume of only, which saves 60% of space compared to SD card, don't underestimate such a small shape, it can save 40% of the volume of digital equipment.

The rapid popularity of SD cards paved the way.

MicroSD (formerly known as TF card) is a new ultra-small and large-capacity mobile memory card, which is about the same size as the most popular SD memory card on the market, or mobile phone SIM card.

The size of the miniSD is one lap smaller than the SD card, with 11 pins.

The microSD (formerly known as the TF card) is about a quarter of the size of the SD card, with 8 pins.

This difference is about the same in terms of speed, and the miniSD has an advantage in terms of capacity.

MiniSD card is the development of SD card, the performance is not much different from the traditional SD card, miniSD card and SD card, both have a data transfer speed of 2MB per second. Like traditional SD cards, miniSD cards also have a hardware write-protect switch to avoid the risk of accidentally deleting stored contents. The miniSD card is characterized by its compact size (the volume is only, which is 40% smaller than the original SD card), stable performance, can be used with a dedicated riser card, and is fully compatible with standard SD card slots.

Moreover, the miniSD card adopts a low-power consumption design, which is more suitable for mobile communication devices than SD cards, so it mainly attacks the information terminals of mobile phones, PDAs, and handheld computers.

Compared with TF cards, miniSD cards are much more common, and as a slimmer multi-** card, miniSD cards are much more widely used in the mobile phone market, such as Motorola MPX100, Panasonic X700, BQ S700 and other brands of mobile phone products support it. At the same time, it can be used as a standard SD card through the expansion card, which is very convenient.

Mini-SD card is a smaller memory card more suitable for small mobile phones developed on the basis of flash memory card (Chinese name: flash memory card) used in digital cameras, PDAs, etc. Although the form factor and interface shape of the mini-SD card are different from the original SD card, the electrical standards such as the interface are the same to ensure compatibility.

Insert the mini-SD card into the dedicated adapter to read and write the mini-SD card through the original SD card slot. However, it does not have an anti-write locking feature like an SD card.

The mini-SD card has 2 more interfaces than the SD card's 9 and has 11 signal lines (Figure 4). The 2 additional signal lines of the mini-SD card are ready for future performance expansion. For example, antenna connections can be used for short-range wireless communication such as contactless ICs.

The remaining 9 signal lines of the mini-SD card are the same standard signal lines as the original SD card.

Mini-SD cards are small SD cards specially developed for digital devices such as mobile phones, and are more compact than SD cards. In the field of SD cards and mini-SD cards, Panasonic is a promoter of industry standards and a major product provider.
