What is a TF card
TF card is also known as T-Flash card, full name: TransFLash, aka: Micro SD, developed by Motorola and SANDISK*** together, launched in 2004. It is a kind of ultra-small card (11*15*1MM), about 1/4 of the SD card, which can be counted as the smallest storage card at present. TF is a small card, SD is a large card, are a flash memory card, TF card size is the smallest, can be after the SD card converter, when the SD card to use. The adapter allows you to use it in devices that use SD as a storage medium.TransFlash was developed primarily for camera phones to capture large images and to be able to download larger video clips.TransFlas cards can be used to store personal data, such as digital photographs, MP3s, games, and apps for cell phones and personal data, and have a built-in copy-protection management system to keep downloaded music, videos, and games protected by the copyright. It also has a built-in copyright protection management system to protect downloaded music, videos and games; the new TransFlash, to be launched in the future, also has an encryption function to protect personal data, financial records and healthcare documents. The compact size of TransFlash allows manufacturers to adopt this design without concern for the size of the phone, and another flexible application is that it can be replaced by the supplier at any time prior to delivery to meet the customer's varying needs, an advantage not available with embedded flash memory. Function MicroSD card is an extremely small flash memory card, its format originated from the creation of SanDisk, originally this kind of memory card is called T-Flash, and TF card (3 cards) later renamed TransFlash; and renamed microSD because by the SD Association (SDA) to adopt. Other memory cards adopted by the SDA include miniSD and SD cards. It is mainly used in cell phones, but because of its small size and increasing storage capacity, it is now used in GPS devices, portable music players and some flash memory disks. With a size of 15mm x 11mm x 1mm, almost the size of a fingernail, it is the smallest memory card available. It can also be used in an SD card slot via an SD adapter. MicroSD cards are available in 128MB, 256MB, 512MB, 1G, 2G, 4G, 8G, 16G and 32G capacities.
What is SD card
SD card is the abbreviation of Secure Digital Card, which is directly translated into Chinese as "安全数字卡", and is a brand new memory card product developed by Matsushita, Toshiba, and SANDISK in the U.S.A. SD card is a completely open standard. Memory card is a completely open standard (system), mostly used for MP3, digital camcorders, digital cameras, e-books, AV equipment, etc., especially is widely used in ultra-thin digital cameras. SD card in shape with the MultiMedia Card card to maintain consistency, the size of the size of the card than the MMC card is slightly thicker, the capacity is also much larger. It is also compatible with the MMC card interface specification. People can't help but suspect that SD card is an upgraded version of MMC. In addition, SD card is 9-pin, the purpose is to improve the transmission speed by turning the transmission method from serial to parallel. Its read/write speed is faster than MMC card, and at the same time, the security is also higher.The biggest feature of SD card is that it can guarantee the security and confidentiality of data through encryption function. It also has a copyright protection technology, the copyright protection technology used is the CPRM technology (Content Protection for Recordable Media) used in DVD.Characteristics of Several Major Brands of SD Cards There are many brands of SD cards on the market today, and the well-known brands have their own characteristics. SANDISK: SANDISK this brand of SD card may be the most common on the market, like this "blue card" basically every digital specialty stores can buy. In fact, SANDISK's SD cards are not all low-speed, there are also high-speed models (black cards), but it seems that they are not yet available in the local market. Kingmax: As a manufacturer of branded memory, KINGMAX has been committed to the development of memory cards in recent years. It uses a unique integrated packaging technology (PIP), making it difficult for counterfeiters to imitate, Kingmax SD card maximum transfer rate of 10MB / s, with waterproof, shockproof performance, anti-pressure three-proof design, it can meet the field shooting a variety of requirements. Panasonic: Panasonic as the creator of the SD standard, its technology can be said to be one of the best sd card on the market.

Kingston: Kingston as the world's number one memory manufacturer, it produces SD card eliminates the interface circuitry, so in the many flash memory products, is the smallest one (size only the size of a postage stamp, the weight of only less than two grams), which is also a lot of digital cameras, MP3 and PDA products have chosen the SD card as the reason for its storage medium. It is only due to the size of the product that it is difficult to increase the capacity of the SD card. In addition, Kingston's SD card products all come with a 5-year warranty.
What is Digital Camcorder Tape
Digital camcorder tape is a tape-like material containing magnetic layers used to record sound and images. Other materials compared to magnetic tape: 1, portable, lightweight, smaller, easier and larger, a variety of storage capacity for purchase, a variety of different read and write speeds for different devices, the formation of different price levels for different consumers to choose from, the abundance of money. 2、Higher security, longer life cycle, can be used for a long time, relatively lower cost. More moisture-proof, adapted to work in more climatic conditions, easy to exchange, easy to disseminate, can be carried in large quantities, can be quickly copied to transfer the data, dual-card machine can be replaced without shutting down the case of the memory card, a single position to avoid changing the recording medium to avoid the impact of the recording screen. 3, data recording is more complete, basically does not produce a mosaic phenomenon, can record the full mode data. The current market tape recording full HD time is much shorter than SD, the relative cost will increase, if you increase the length of the tape is a new challenge to the entire servo system, the need to adjust the entire industry chain, no manufacturers are willing to do so, with the current tape speed recording high compression rate video data has industrial bottlenecks, but also does not fit the times of the development of the full HD mode with the current tape recording of the civil camera market The main reason for this is that it is not possible to see the current tape recordings.
What is a Sony Memory Stick
The Memory Stick, also known as an MS Card, is a removable flash memory card format storage device manufactured by Sony and introduced to the market in October 1998; it also summarizes the entire Memory Stick memory card series. The family includes the Memory Stick PRO (which allows for better maximum storage capacity and faster transfer speeds), the Memory Stick Duo (a smaller format version of the Memory Stick, including the PRO Duo), and the Memory Stick Micro (M2), which is smaller than the Duo. Memory Stick family is very large, there are many types, generally speaking, is divided into the following categories: blue memory stick commonly known as "blue bar", is the most used memory stick, mostly used in digital cameras and digital camcorders it has a copyright protection function, mostly used in Sony's digital walkman; "Memory Stick Pro" is the newest version of the Memory Stick, which is used in digital cameras and digital camcorders; "Memory Stick Pro" is the newest version of the Memory Stick. Stick Pro" is a newly released soon a memory stick specifications, there is no Chinese name, it is not only the same as the White Stick with copyright protection, and very fast, the capacity is as high as 32GB; "Memory Stick DUO" is the current memory stick family Memory Stick DUO" is currently the most compact memory stick family, it can be compatible with the memory stick interface through the adapter, it is also divided into two kinds of blue and white, blue named "Memory Stick DUO", white named "Memory Stick PRO MAGICGATE The blue Memory Stick is called "Memory Stick DUO" and the white Memory Stick is called "Memory Stick PRO MAGICGATE", which has a copyright protection function and a larger capacity. Characteristics of Memory Stick In addition to its compact size, high stability and copyright protection function, and convenience of use in various Memory Stick series products, the advantages of Memory Stick also lie in the large number of products launched by Sony that utilize the technology, such as DV camcorders, digital cameras, VAIO personal computers, color printers, Walkmans, IC tape recorders, and LCD TVs, etc., and the PC card converter, 3.5-inch floppy disk converter, and PC card converter, 3.5-inch floppy disk converter, and so on. The full line of accessories such as PC card converter, 3.5-inch floppy disk converter, parallel export converter and USB reader/writer makes the Memory Stick easy to realize the connection with PCs and Macs. Since the launch of the Memory Stick, a series of companies such as Samsung, Aiwa, Sanyo, Casio, Fujitsu, Olympus, Sharp and others have expressed support for the format. Sony is also currently seeking recognition of the Memory Stick format from the home electronics and IT industries. Sony will introduce more products representing the latest development of memory stick to the domestic market in the future. The drawbacks of the Memory Stick are that it can only be used in Sony digital cameras and PSPs, and that its capacity is not yet large enough. Sony on the basis of the memory stick will reduce the volume to about 1/3, designed and manufactured memory stick Duo, the external dimensions of only 31 × 20 × 1.6mm, the weight has also been reduced by a factor of 2 grams, which is very similar to the xD card, very easy to carry. This memory stick Duo is convenient for use in compact cell phones and digital cameras, as well as in various electronic products such as mp3 players. In order to obtain a larger capacity and higher speed, Sony launched a new memory stick PRO, which is developed by Sony and Sandisk Corporation **** with the same development, appearance and volume than the memory stick are unchanged, but can be realized in 8GB capacity, the old equipment will not be able to use this new memory stick PRO, but now the production of digital products with memory stick PRO slot can be backward compatible with the use of traditional memory sticks. However, digital products manufactured today that have a Memory Stick PRO slot can be backward compatible and use a traditional Memory Stick. In addition to serial transfer, Memory Stick PRO also supports parallel transfer for simultaneous transmission and reception of multiple data. In parallel transfer mode, data is transmitted at speeds greater than 160 Mbps (theoretical), making it possible to record DVD-quality motion pictures in real time. With this high speed, the Memory Stick PRO is equally capable of supporting the advanced solutions brought about by the upcoming broadband era. There are no blue or white bars on the Memory Stick PRO, and all Memory Stick PROs come with copyright protection.
What does class mean for memory card
The SD Association's transfer specifications for TF memory cards (SDHC): transfer speeds (minimum speeds for write speeds and read speeds) are defined as Class2 (2MB/sec), Class4 (4MB/sec), Class6 (6MB/sec), Class10 (10MB/sec). SD2.0 specification for the performance of the SD card is divided into the following levels, different levels to meet the requirements of different applications: Class 0: including less than Class 2 and not marked Speed Class; Class 2: to meet the viewing of ordinary MPEG4 MPEG2 movies, SDTV, digital camcorders; Class 4: can be used for smooth playback of HDTV (HDTV); Class 4: can be used for smooth playback of HDTV (HDTV).

What is the difference between SD and SDHC and SDXC cards
SD card, SDHC card, SDXC card difference in the specifications are not the same, the SD card supports a maximum capacity of 2GB, SDHC supports a maximum capacity of 32GB, SDXC supports a maximum capacity of 2TB (2048GB), support for SDXC card digital devices are compatible with support for SD cards and SDHC cards. SDHC card. If the device only supports SDHC card, then this device cannot use SDXC card, but is compatible with SD card. If the device only supports SD card, then it is not compatible with SDXC, SDHC card. SD is the earlier version of it and is said to have evolved from MMC. Maximum support for 2GB size capacity SD memory card is a small storage media developed by Panasonic, Toshiba, SanDisk 3 companies *** with the launch of the SD memory card at the same time, while the establishment of the Secure Storage Digital Card Association (Secure Digital Card Association; SDA) to develop relevant At the same time, the Secure Digital Card Association (SDA) was established to formulate relevant specifications and take charge of the promotion of SD memory cards. After years of development, SD card has been the world's most popular electronic products memory card format, applicable to cell phones, digital cameras (DSC), MP3 music players, personal computers and other electronic products. SDHC is a high-capacity SD card, also known as SD High Capacity, supports a maximum size capacity of 32GB SDHC, Secure Digital High Capacity, high-capacity SD, that is to say, more than 2G SD are called SDHC, because the early SD use FAT16 file system, and does not support high-capacity, and the SDHC is upgraded to FAT32 to support large capacity over 2G. SDXC (SD eXtended Capacity) is a new standard released last year in 2009, support for a maximum of 2TB of the size of the capacity SDXC is the abbreviation of SD eXtended Capacity, is a new standard, in addition to the capacity can be upgraded to a maximum of 2T in addition to the main support for the 300M/s transfer speed, that is to say, is the This means that it is a "high-speed SD" card. However, not many digital cameras support SDXC cards, mainly new products launched this year, and SDXC is not backward compatible, does not support ordinary SD and SDHC card slots and card readers. For most digital cameras and DSLRs, the speed of a high-speed SDHC memory card is sufficient for high-speed continuous shooting and HD video shooting.
