SDXC cards utilize the exFAT file system, the use of which is governed by a proprietary license, thereby limiting its legal availability to a small set of operating systems. Therefore, exFAT-formatted SDXC cards are not a universally readable exchange medium.

The speed class rating was based on request from movie and video companies, as video recording in different formats and resolutions requires certain write speeds when recording to the card. As a result, the goal of the class ratings is to allow consumers to easily identify cards that meet the minimum level of required performance based on their use or application of the host device. Below is a listing of typical applications for each speed class.
The first Satechi Type-C SD and microSD Card Reader unit we tested did not recognize SD or microSD cards on three different Windows laptops. The second unit we tested read SD cards only with the “Satechi” logo facing down, and it read microSD cards only with the logo facing up. When it did work, it had slow SD and microSD speeds between 30 MB/s and 40 MB/s when they should have been about twice that.
This is a preowned video game accessory. It is guaranteed to work on your GameCube video game console and may not include a box or instruction manual. Actual color of product may vary. With the GameCube memory card, you can save all your game data quickly and safely. This memory card has plenty of space for all your favorite games.
I think it’s pretty cool you can use standard SD and Micro SD in it, but I opted to use my 16GB Micro SDHC from my old phone because standard SD sticks WAY out (be sure to insert the Micro SD upside down). The Micro SD still sticks out from the side of the reader about 1/4″, and I’m curious to know why they couldn’t have designed the reader to accept Micro SD from the rear of it so you won’t accidentally tug on it when inserting/removing the reader.

I’m sure you could still find a new GameCube at your local electronics or gaming store. Try EBgames, GameStop, or even a BestBuy. New ones should run you $99 or less, but a used one could be as cheap as $50. If you have the money though, you might want to just invest in a Wii since it’s backwards compatible anyways.m3ss
However, SD is much more open than Memory Stick, for which no public documentation nor any documented legacy implementation is available. All SD cards can be accessed freely using the well-documented SPI bus.
Easily add storage to a number of personal electronic devices with a compatible flash memory card. Maybe you’d like a flash card for your digital camera so you can take more photos or videos. There are also memory cards that work with smart phones or MP3 players. A versatile and compact storage device, flash memory cards from PNY, Duracell and Dane-Elec can give you extra room to create or store your memories.
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*
Video Speed Class is defined to answer a demand for high resolution and high quality 4K8K video recording and it also has an important feature to support next generation flash memory such as 3D NAND. Furthermore, as it covers speed of HD(2K) video, it is possible to integrate into Video Speed Class from now on.

What’s even scarier – the dead device becomes very hot when plugged in! To me, this indicates that the reader was NOT designed for becoming hot, and became damaged from the heat. Furthermore, it means that the power circuitry is faulty – why would a non-working device draw that much power to become painfully hot? Because of these problems, it becomes very dangerous to plug into a computer. Most modern computers come with current protection to prevent anything bad from happening due to faulty devices, but I wouldn’t take that chance.
An article from CMU in 2015 writes that “Today’s flash devices, which do not require flash refresh, have a typical retention age of 1 year at room temperature.” And that temperature can lower the retention time exponentially. The phenomenon can be modeled by Arrhenius law.[79]
TransFlash cards are sold in 16MB and 32MB sizes. microSD cards are sold in many sizes, from 64 MB to 32 GB, while microSDHC cards are sold in sizes between 4 GB to 64 GB. Larger ones are microSDXC memory cards, sold in sizes between 8 GB and 256 GB. [5]
We do not deliver on Sundays, but do sometimes deliver on Saturday depending on the carrier that is delivering your order. The best way to determine the date of delivery is to check the status in My Account .
On the left side, there may be a write-protection notch. If the notch is omitted, the card can be read and written. If the card is notched, it is read-only. If the card has a notch and a sliding tab which covers the notch, the user can slide the tab upward (toward the contacts) to declare the card read/write, or downward to declare it read-only. The diagram to the right shows an orange sliding write-protect tab in both the unlocked and locked positions.
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.
Neither the Kanex USB-C Card Reader nor the Plugable USB Type-C Flash Memory Card Reader supports CF cards. Both of them are larger and more expensive than the Cable Matters model we recommend, lack indicator lights, and have an extra Memory Stick slot that most people don’t need.
SDHC host devices are required to accept older SD cards.[10] However, older host devices do not recognize SDHC or SDXC memory cards, although some devices can do so through a firmware upgrade.[11] Older Windows operating systems released before Windows 7 require patches or service packs to support access to SDHC cards.[12][13][14]
As discussed above, the memory card options available to you are limited by the device you are using it in. Each device has a discrete set of compatible card choices. Check your device carefully, as many cameras have multiple memory card slots, giving you more options of what cards you can use.

Common flash devices such as USB flash drives and memory cards provide only a block-level interface, or flash translation layer (FTL), which writes to a different cell each time to wear-level the device. This prevents incremental writing within a block; however, it does help the device from being prematurely worn out by intensive write patterns.
I ordered the IOGEAR SD/MicroSD/MMC Card Reader/Writer GFR204SD and got it in the mail about three days after ordering [impressive]. As some other reviewers have noted, it does feel a little flimsy, and care should be taken to insert and remove it AS STRAIGHT AS YOU CAN from whatever device you use it in, especially when it’s a very tight fit into the USB port.
Ok, don’t know why I’m doing this now but I bought it back in 2013 when I was 11. It’s a cheap price but with that you’ll expect some downsides. For example, (I still have mine by the way.) With my memory card you’ll need to push it in with force not because it’s big (its a perfect size) but because it has trouble reading it. It’ll constantly not recognize until you find the sweet spot. You won’t be moving the gamecube around anyway so I think it’s a pretty good deal. But still, could be been just a tiny bit better.
At the 2000 Consumer Electronics Show (CES) trade show, the three companies announced the creation of the SD Association (SDA) to promote SD cards. The SD Association, headquartered in San Ramon, California, United States, started with about 30 companies and today consists of about 1,000 product manufacturers that make interoperable memory cards and devices. Early samples of the SD Card became available in the first quarter of 2000, with production quantities of 32 and 64 MB cards available three months later.
microSD is a type of removable flash memory card used for storing information. SD is an abbreviation of Secure Digital, and microSD cards are sometimes referred to as µSD or uSD.[1] The cards are used in mobile phones and other mobile devices.

Version 5.0 was announced in February 2016 at CP+ 2016, and added “Video Speed Class” ratings for UHS cards to handle higher resolution video formats like 8K.[17][18] The new ratings define a minimum write speed of 90 MB/s.[19][20]
The low-level interface to flash memory chips differs from those of other memory types such as DRAM, ROM, and EEPROM, which support bit-alterability (both zero to one and one to zero) and random access via externally accessible address buses.
The presence of a notch, and the presence and position of a tab, have no effect on the SD card’s operation. A host device that supports write protection should refuse to write to an SD card that is designated read-only in this way. Some host devices do not support write protection, which is an optional feature of the SD specification. Drivers and devices that do obey a read-only indication may give the user a way to override it.
Application Performance Class is a newly defined standard from the SD Specification 5.1 and 6.0 which not only define sequential Reading Speeds but also mandates a minimum IOPS for reading and writing. Class A1 requires a minimum of 1500 reading and 500 writing operations per second, while class A2 requires 4000 and 2000 IOPS.[43]
