About 128GB SD CARD DATA RECOVERY SOFTWARE, everything you should know
There is no doubt that 128GB SD CARD DATA RECOVERY SOFTWARE is currently the most widely used memory card. For most users, it is necessary to know about 128GB SD CARD DATA RECOVERY SOFTWARE.
"size"
128GB SD CARD DATA RECOVERY The SOFTWARE family has a total of 3 members of SD, Mini SD, and Micro SD, and the size is reduced in turn. Standard 128GB SD CARD DATA RECOVERY SOFTWARE is used in most cameras and camcorders. The body has a write-protect switch - but it does not affect the internals of the memory card, but affects the identification of the card reader. Mini 128GB SD CARD DATA RECOVERY SOFTWARE has withdrawn from the stage of history. Micro 128GB SD CARD DATA RECOVERY SOFTWARE, also known as TF card, is mainly used in mobile phones, sports cameras, drones and other products.
▲Dimensions of different 128GB SD CARD DATA RECOVERY SOFTWARE
Micro 128GB SD CARD DATA RECOVERY SOFTWARE can be converted to the standard 128GB SD CARD DATA RECOVERY SOFTWARE via the card holder. This conversion does not slow down, but it can reduce system reliability (after all, one more connection). Why is the Micro 128GB SD CARD DATA RECOVERY SOFTWARE of the same capacity and approximate speed cheaper than 128GB SD CARD DATA RECOVERY SOFTWARE? Sorry, ET did not find a reliable explanation.

"capacity"
We collectively call 128GB SD CARD DATA RECOVERY SOFTWARE, in fact there are multiple versions in terms of maximum capacity. The original 128GB SD CARD DATA RECOVERY SOFTWARE, with a maximum capacity of only 2GB, has now withdrawn from mainstream view (if you have a hobby of collecting old digital cameras, you may need this 128GB SD CARD DATA RECOVERY SOFTWARE). The most common SDHC memory cards and SDXC memory cards have a maximum capacity of 32GB and 2TB respectively. The new SDUC memory card can achieve a theoretical capacity of 128TB - oh, I don't know if I can see this full capacity 128GB SD CARD DATA RECOVERY SOFTWARE in my lifetime.
It is worth mentioning that 128GB SD CARD DATA RECOVERY SOFTWARE (SDXC and SDUC) above 64GB adopts EXFAT format, and the size of a single file can be larger than 4GB. Recommended for long-term continuous recording, 4K high-rate video capture user selection.
Capacity compatibility Want to use a large capacity 128GB SD CARD DATA RECOVERY SOFTWARE (such as SDXC card or future SDUC card), you need to get support for the device (camera, mobile phone, card reader, operating system). For example, if you use an SDXC card on a camera that only supports SDHC cards, you will not be able to use it.
▲Support for large-capacity 128GB SD CARD DATA RECOVERY SOFTWARE devices, which can use a small capacity of 128GB SD CARD DATA RECOVERY SOFTWARE; otherwise, it cannot.
Speed ​​grade
The speed grade is 128GB SD CARD DATA RECOVERY SOFTWARE Alliance specified performance specifications, but also 128GB SD CARD DATA RECOVERY SOFTWARE manufacturers need to print on the product body, the outer packaging. The speed grade usually only reflects the minimum performance level of 128GB SD CARD DATA RECOVERY SOFTWARE, which does not represent actual performance.
No UHS: Single row contact, the highest standard C10 (continuous write speed is not less than 10MB/s), the theoretical speed does not exceed 25MB/s (usually refers to the reading speed, the writing speed will be slightly lower). This card has basically withdrawn from the market.
UHS-I: Single row contacts, the highest standard C10, U3, V30 (continuous write speed 30MB/s), theoretical speed 104MB/s. This is the most important product in the market.
UHS-II: Double row contacts, up to standard C10, U3, V90 (continuous write speed 90MB/s). Full-duplex mode theoretical speed 156MB/s (most cameras), half-duplex mode theoretical speed 312MB/s (reader, etc.).
UHS-III: Double row contacts, up to standard C10, U3, V90, full-duplex mode up to 624MB/s. However, there are currently no actual products.
▲128GB SD CARD DATA RECOVERY SOFTWARE speed grade and corresponding video format
SD Express: Double-row contacts with PCIe 3.0 bus and NVMe support for ultra-high speeds of 985MB/s. Currently, SanDisk (Western Digital) has launched a prototype product. It should be noted that SD Express can only be backward compatible with UHS-I, and does not support UHS-II or UHS-III - that is, when the memory card or one of the devices does not support SD Express, the maximum speed that the system can reach is 104MB/s.
Application performance: This is the performance standard when considering Micro 128GB SD CARD DATA RECOVERY SOFTWARE with smart phones. There are two gears A1 and A2. The standard requires a sustained write speed of not high (10MB/s), but with clear random read and write performance requirements.
Speed ​​Level Compatibility The highest read/write speed that a system can achieve depends on the lower speed of the memory card and device. For example, using a UHS-II card on a device that only supports UHS-I cards can only achieve the highest theoretical speed of UHS-I.
"Which cameras support UHS-II cards? When is it necessary to use the UHS-II card?
As of July 2018, the camera that clearly supports UHS-II has the following models.
Note 1: Although some camera specifications are written to be compatible with UHS-II cards, they are actually only usable (in fact, they can be used) and cannot play the performance of UHS-II cards.
Note 2: The camera that supports UHS-II is usually only able to achieve a write speed of about 160MB/s, that is, it works in full-duplex mode (very common sense, full-duplex is half-speed, half-duplex is full speed) .
Considering that the current UHS-II card price is still relatively high, you can buy a high-speed UHS-I card first. If you actually encounter high-speed continuous shooting, the sustained power is not enough, or the writing delay is longer after continuous shooting. In case, consider purchasing a UHS-II card.

So what about 4K video shooting? In fact, the 4K shooting of most cameras does not require a high speed of the memory card, U3 level (continuous writing speed of not less than 30MB / s) is enough.
Why does the video automatically terminate or prompt the memory card to be slow when recording video? 1 It is true that the writing speed is slow. For example, you are using a Canon SLR (in the old MOV format, where 5D4 is best for CF cards with 4K) or 4K video at 400Mbps (Panasonic GH5 series). 2 The memory card has not passed the corresponding certification. When a Sony camera records at a 100 Mbps rate, it will recognize if the memory card has reached the U3 rating. Some cards have reached the standard speed, but because the corresponding certification has not been obtained (such as the launch time is earlier than the U3 standard time), the camera thinks it is not up to standard. 3 The upper limit of the camera's single-segment recording time is reached. For example, Sony RX100M4, M5, M6 shooting 4K, single paragraph
