The first thing to be certain of when purchasing an SD card is what kind works in your camera. Is it a regular SD card or a microSD card? Keep in mind, many microSD cards come with adapters that let you use them in devices that normally take SD cards.
I have been an apple iPad user for years and the attraction to apple was due to the fact that all of their accessories worked well with all apple devices. I was I have been an apple iPad user for years and the attraction to apple was due to the fact that all of their accessories worked well with all apple devices. I was very disappointed on my trip to Antarctica to find that I couldn’t transfer my photos from my SD card to my iPad because I received an error message stating accessory not supported by this iPad. When I investigated this error message online, I saw a plethora of posts dating back to October of 2017 that the update to ios11 has made this accessory useless. Apple has had 5 months since the update to rectify this issue but has chosen not to. Are they going to introduce a new SD card reader so that everyone can rush to the store and buy it so that it is compatible with ios11? Shame on you, Apple. More(Read full review)
Howard Cheng, technical director of Nintendo technology development, said the company’s goal was to select a “simple RISC architecture” to help speed development of games by making it easier on software developers. IGN reported that the system was “designed from the get-go to attract third-party developers by offering more power at a cheaper price. Nintendo’s design doc for the console specifies that cost is of utmost importance, followed by space.” Hardware partner ArtX’s Vice President Greg Buchner stated that their guiding thought on the console’s hardware design was to target the developers rather than the players, and to “look into a crystal ball” and discern “what’s going to allow the Miyamoto-sans of the world to develop the best games”.
Hope in the future that Amazon punishes vendors who ship inferior, counterfeit, or products different than described or pictured. Right now, the only way I see to determine if this might be the case is to S L O W L Y read the 1 and 2 Star reviews for a product. Four or maybe even two years ago, you could comfortably make a purchase based on 4-Stars or above. No more – especially on these commodity products where confusion exists regarding product specifications. [On this product alone: SD vs. SDXC vs. SDHC; Suitability of Capacity; Choice of writing speed for application. For in-depth information see SDCard dot ORG] An overall rating is NO LONGER a sufficient criterion for a purchasing decision since many of these commodity type products have their reviews gamed by paid reviewers.
The majority of new cameras, camcorders and other devices use Secure Digital (SD) or microSD memory cards. MicroSD is the smaller variant of the SD memory card and, because of its compact size, microSD is used in certain mobile devices as well.
Multi Media Cards have the same physical appearance as Secure Digital Cards, but just without the access lock. They are used as an alternative to SD and will fit most compatible cameras, although transfer rates are lower.

An SSD with NAND flash memory chips delivers significantly higher performance than traditional magnetic media, such as HDDs and tape. Flash drives also consume less power and produce less heat than HDDs. Enterprise storage systems equipped with flash drives are capable of low latency, which is measured in microseconds or milliseconds.
A memory card, flash card or memory cartridge is an electronic flash memory data storage device used for storing digital information. These are commonly used in portable electronic devices, such as digital cameras, mobile phones, laptop computers, tablets, PDAs, portable media players, video game consoles, synthesizers, electronic keyboards, and digital pianos.
The companies also formed the SD Association (SDA), a non-profit organization, in January 2000 to promote and create SD Card standards. SDA today has about 1,000 member companies. The SDA uses several trademarked logos owned and licensed by SD-3C to enforce compliance with its specifications and assure users of compatibility.
If you’re planning to store photos and videos on your memory card, you may need to consider write speed as well as capacity. If your photography needs are fairly basic, such as taking clear, quality pictures of family vacations or get-togethers, any average memory card, like a Speed Class 10, should provide sufficient speed and reliability. However, if you plan on taking video including 4K Ultra HD or HRD, you’ll require faster speed and more capacity.
I see 1-Star reviews being posted for this same card. Take the time to assure BEFORE you Click “Add to Cart” that your source is “SOLD BY SANDISK, FULFILLED BY AMAZON.” BUY FROM OTHER SOURCES AND YOU MAY GET BURNED*
If you’re just starting out or just do photography as a part-time hobby then, generally speaking, the most important feature to look for when buying a card is the capacity. Most memory card manufacturers publish tables on their websites to show how many images you can save on the specific card. Different file types, compression and resolution all affect the size of each file, so the number of images you can put on one card from one camera to the next is never the same. Between 1GB and 8GB storage should be enough for an average beginner photographer using a compact camera and these won’t break your bank either.
The speed class rating does not totally characterize card performance. Different cards of the same class may vary considerably while meeting class specifications. A card’s speed depends on many factors, including:
I bought this during black friday and I got a huge discount using my rewards points also. I primarlly use it for my Galaxy Note 2. After 2 months, the phone says that the sd card was unexpectedly unmouted. Then my card was not recognized and blank. I could not reformat it in any way since my computer and any other devices can not recognize it. After a successfull fix, 2 days later same thing happen and now I can not get it to work at all. I do not know who to get a hold on to get this fixed. But it is a bummer since I it is a nice size and value. But it just failed horribly.
The higher speed rates are achieved by using a two-lane low voltage (0.4 V pp) differential interface. Each lane is capable of transferring up to 156 MB/s. In full duplex mode, one lane is used for Transmit while the other is used for Receive. In half duplex mode both lanes are used for the same direction of data transfer allowing a double data rate at the same clock speed. In addition to enabling higher data rates, the UHS-II interface allows for lower interface power consumption, lower I/O voltage and lower electromagnetic interference (EMI).
NAND flash also uses floating-gate transistors, but they are connected in a way that resembles a NAND gate: several transistors are connected in series, and the bit line is pulled low only if all the word lines are pulled high (above the transistors’ VT). These groups are then connected via some additional transistors to a NOR-style bit line array in the same way that single transistors are linked in NOR flash.
If you use only SD and microSD cards, you should get the Cable Matters USB 3.1 Type-C Dual Slot Card Reader. The Cable Matters reader has similar speeds to the IOGear and Transcend readers, but it doesn’t support CF cards. It’s smaller, lighter, and cheaper than our other top picks, plus it has good speeds and an indicator light. It also comes with only a one-year warranty.
The most prominent factor in choosing a memory card is what device you’ll be using it in. Most devices have a specific set of memory cards that are compatible with them. A smartphone or tablet may have only one slot, while a higher-end DSLR or mirrorless camera can have several. Check your device or owner’s manual, and take note of what formats you’ll be able to choose from.
These are SD cards but with a much higher capacity and faster processing speeds. These have a maximum capacity of 2TB (Terabytes). Similar to SDHC, in that an SDXC fits in a normal SD slot – but your camera may not be able to recognise this newer technology, so always check in advance. Computers also need to be able to read the exFAT filesystem to be compatible with SDXC. Currently Linux, Windows 7, Mac OSX (Snow Leopard) and some earlier versions of Microsoft Windows are compatible.
If you’re planning to use your camera, smartphone or camcorder to take high-resolution video, such a 1080P or 4K UHD, you’ll want to make sure you have a large capacity card to avoid needing to empty it after a small amount of footage.

Flash memory is used in enterprise server, storage and networking technology, as well as in a wide range of consumer devices, including USB flash drives, mobile phones, digital cameras, tablet computers, PC cards in notebook computers and embedded controllers. For instance, NAND flash-based solid-state drives are often used to accelerate the performance of I/O-intensive applications. NOR flash memory is often used to hold control code, such as the basic input/output system (BIOS), in a PC.
The SDA announced the microSD format at CTIA Wireless 2005 on March 14, 2005, and the final microSD details were announced on July 13, 2005. When they were first sold, the microSD format was sold in sizes of 32, 64, and 128 MB. SanDisk made a 4 GB microSD card on July 2006, at first costing $99 (USD). Since then, the prices for flash memory devices have become much lower. At the time of April 2009, the same 4 GB card could be bought for as low as $12 (USD) at department stores, and by May 2009, for as low as $6 (USD) at online electronics stores. In January 2010, a 16 GB micro SD card class 2 cost about $40 (USD), and a 4 GB class 2 micro SD card about $8 (USD).
NAND flash has reduced erase and write times, and requires less chip area per cell, thus allowing greater storage density and lower cost per bit than NOR flash; it also has up to 10 times the endurance of NOR flash. However, the I/O interface of NAND flash does not provide a random-access external address bus. Rather, data must be read on a block-wise basis, with typical block sizes of hundreds to thousands of bits. This makes NAND flash unsuitable as a drop-in replacement for program ROM, since most microprocessors and microcontrollers require byte-level random access. In this regard, NAND flash is similar to other secondary data storage devices, such as hard disks and optical media, and is thus highly suitable for use in mass-storage devices, such as memory cards. The first NAND-based removable media format was SmartMedia in 1995, and many others have followed, including:
Some prosumer and professional digital cameras continued to offer CompactFlash (CF), either on a second card slot or as the only storage, as CF supports much higher maximum capacities and historically was cheaper for the same capacity.
SD cards are also available in various speeds. If you’re using a point-and-shoot digital camera or a standard-definition pocket camcorder, speed class won’t matter much. If you’re shooting high-resolution RAW photos with a digital SLR, however, you need a quick card to take more than two or three shots at a time. SD cards are generally described by their Speed Class, ranging from Class 2 (slowest) to Class 10 (fastest). There’s also a separate, even faster category called UHS Class 1 (for Ultra High Speed), but most current devices can’t use them.
Version 6.0, released in February 2017, added two new data rates to the standard. FD312 provides 312 MB/s while FD624 doubles that. Both are full-duplex. The physical interface and pin-layout are the same as with UHS-II, retaining backward compatibility.
In April 2006, the SDA released a detailed specification for the non-security related parts of the SD memory card standard and for the Secure Digital Input Output (SDIO) cards and the standard SD host controller.
In our SD card test, the IOGear had read and write speeds of 84 MB/s and 72 MB/s, respectively. When reading and writing to the microSD card, it had speeds of 85 MB/s and 64 MB/s, and in our CF card test, it had read and write speeds of 144 MB/s and 114 MB/s.
Unique to the GameCube is the controller’s prominent size and placement of the A button. Having been the primary action button in past Nintendo controller designs, it was given a larger size and more centralized placement for the GameCube. The rubberized analog stick in combination with the controller’s overall button orientation was intended to reduce the dreaded “Nintendo thumb” – a term used to describe pain in any part of the hands, wrists, forearms, and shoulders as a result of long-term play.
Early SDSC host devices that assume 512-byte blocks therefore do not fully support the insertion of 2 GB or 4 GB cards. In some cases, the host device can read data that happens to reside in the first 1 GB of the card. If the assumption is made in the driver software, success may be version-dependent. In addition, any host device might not support a 4 GB SDSC card, since the specification lets it assume that 2 GB is the maximum for these cards.
The SD card specification defines three physical sizes. The SD and SDHC families are available in all three sizes, but the SDXC family is not available in the mini size, and the SDIO family is not available in the micro size. Smaller cards are usable in larger slots through use of a passive adapter.
