Speed class is a minimum sustained writing performance speed for SD cards. This means that it’s the speed it can write data to the card consistently. Speed class is mainly useful when you’re shopping for a card to use with video recording, since you’ll be continuously writing to the card. The higher the speed class, the more data you can write to the card in the same amount of time. Pay attention to this when deciding what card you need for the desired resolution you’d like to film in.
I searched for advice on how to fix this – consensus seemed to be to uninstall the SDA driver and reinstall it.  Fine – except I cannot find a place to download the driver!  I have an integrated SD Card reader in my ASUS X012B Notebook PC
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.
If you’re an amateur photographer, or just starting out, chances are the most important factor in a memory card will be capacity. The capacity is measured in gigabytes(GB) and determines how much your card can hold. A higher capacity can help you if you’ll be taking photos on a trip and are unable to transfer them onto a computer, or if you will be taking high-definition photos to be used for print making.
At its outset the Association represented just 14 member companies and has grown into a global alliance comprised of around 1,000 member companies. By developing and adopting SD standards, members enjoy better compatibility of member cards between devices, greatly enhancing consumer enjoyment and convenience.

Reliability Qualification results show that the projected data retention failure rate is much less than 1 PPM over 20 years at 85°C or 100 years at 25°C
Over half the energy used by a 1.8 V NAND flash chip is lost in the charge pump itself. Since boost converters are inherently more efficient than charge pumps, researchers developing low-power SSDs have proposed returning to the dual Vcc/Vpp supply voltages used on all the early flash chips, driving the high Vpp voltage for all flash chips in a SSD with a single shared external boost converter.[14][15][16][17][18][19][20][21]
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.
Dave, thanks.  There wasn’t an item as you suggested under “disk drives” – but after rebooting the notebook with the SD Card inserted,  I can now see an SD Host Adaptor (“SDA Standard Compliant SD Host Controller”). 
To play online, players must install an official broadband or modem adapter in their system since the GameCube does not have out of the box network capabilities. Nintendo never commissioned any servers or internet services to interface with the console, but allowed other publishers to do so and made them responsible for managing the online experiences for their games.[69]
They’re also an improvement over optical storage like CDs and DVDs, which are easily scratched. Prices of the drives have come down so much that many companies give them to clients instead of printing reports and wasting paper and ink. In some schools, students are required to have them.

Professionals should also look at how reliable a card is as you can’t take the risk of losing all your photos. This can be worked out by Mean Time Before Failure (MTBF). SanDisk claims a MTBF of over 1,000,000 hours for its memory cards – that’s almost 115 years before the average card is expected to fail.
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.
With no moving parts for less wear and tear, the Standard SD memory card provides reliable performance. SanDisk designed their Standard SD memory cards to withstand harsh operating conditions. The cards are waterproof, temperature proof, shock and vibration proof, and x-ray proof2. No matter where your travels take you, you’ll always be able to capture the most memorable moments.
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]
The microSD format was made by the company SanDisk. It was first called T-Flash, and then TransFlash, before being named microSD when it started to be used by the SD Card Association (SDA). Other flash card formats approved by the SDA include miniSD and standard SD card.
Electronic devices have delivered incredible convenience and freedom, however storage remains a crucial aspect of the digital experience. Built-in storage capacity is a hard limit on what’s possible, but this can now be extended with an external (removable) memory card. These are generally referred to as sd memory card, Mini SD, SDXC, TF card or microSD card, however the standard term remains memory card. These are essential for a vast range of devices including mobile phones, tablets, cameras, PSP, notebooks, and more. GearBest delivers a comprehensive selection of the very latest flash memory card deals to keep your data secure and you connected to a world of multimedia and files.
I’d be more than happy with the Aukey reader if it was didn’t have the card reading failure. I don’t care about blocking nearby ports, I don’t care about CF support, I don’t care about absolute top speed, I care about having a very small reader for my daily gear kit. And how could the Hyperdrive be blocking “the only other port” when you can simply turn it 180 degrees?
Since late 2009, newer Apple computers with installed SD card readers have been able to boot in macOS from SD storage devices, when properly formatted to Mac OS Extended file format and the default partition table set to GUID Partition Table.[97] (See Other file systems below).
I bought this because all of the reviews were better than any of the others that I had seen on similar cards. Worked fine for the first day on my Gamecube, but as of today (a few days after originally using the card) it’s now stating that either there is no memory card in slot A or that it’s been corrupted and needs to be formatted. Even after formatting once and just settling for the fact that I’d have to unlock characters over again in SSBM. Now I have to try and hunt down another memory card.

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.
If you use a camera or cards that support UHS-II speeds, we recommend the Verbatim USB-C Pocket Card Reader. The Verbatim had read and write speeds of 227 MB/s and 219 MB/s, respectively—around 2.5 times the speed of our top pick—but it cannot read multiple cards at once. It also lacks a CF card slot (so high-end DSLR owners may want to look at our pick for traditional USB ports, along with an adapter if they need USB-C compatibility) and an indicator light, but it costs around the same price as our top pick and comes with a one-year warranty.
In 2001, SD card  is mainly for digital cameras, mobile phones, laptops and game consoles  from the beginning of development to popular. These memory cards are combined in a small size (32 x 24 x 2.1 mm) and good strength and have become a practical tool for storing different types of data, (from photos and videos to files and applications)  in recent years.
The Kingston had read and write speeds of 186 MB/s and 172 MB/s, respectively, during our SD card test—it’s slower than Verbatim’s USB-C reader, but it had the most consistent performance of the USB-A readers we tested. In our microSD card test, the Kingston had expected read and write speeds of 90 MB/s and 68 MB/s. It was a little slower than our other picks when reading and writing to a CF card, with speeds of 144 MB/s and 136 MB/s, respectively.
This reader does exactly what it says – it can read and write regular SD cards and MicroSD cards. The speeds aren’t amazing, but it will get the job done. It takes around a minute or more to transfer a 1 GB file, versus a USB 3.0 reader (on USB 2.0) taking around 30 seconds or less. The USB 3.0 reader I’m using now is this: Transcend Information USB 3.0 Card Reader (TS-RDF5K)
Most types of memory cards available have constantly powered, nonvolatile memory, particularly NAND flash. Nonvolatile memory safeguards data in the event of a power outage, software bug or other disruption, and also eliminates the need to periodically refresh data on the memory card. Because memory cards use solid-state media, they involve no moving parts and are less likely to suffer mechanical difficulties.

Early versions of the SD specification were available only after agreeing to a non-disclosure agreement (NDA) that prohibited development of an open source driver. However, the system was eventually reverse-engineered, and free software drivers provided access to SD cards that did not use DRM. Since then, the SDA has provided a simplified version of the specification under a less restrictive license.[115] Although most open-source drivers were written before this, it has helped to solve compatibility issues.
Flash memory incorporates the use of floating-gate transistors to store data. Floating-gate transistors, or floating gate MOSFET (FGMOS), is similar to MOSFET, which is a transistor used for amplifying or switching electronic signals. Floating-gate transistors are electrically isolated and use a floating node in direct current (DC). Flash memory is similar to the standard MOFSET, except the transistor has two gates instead of one.

The Unitek USB-C Card Reader is the best SD card reader for most people because it produced reliably fast speeds during our SD, microSD, and CF tests, and it has a pocketable design (with a useful indicator light) that’s easy to use. It’s also affordable at around $20, and comes with a two-year warranty.
There are also hybrid techniques such as hybrid drive and ReadyBoost that attempt to combine the advantages of both technologies, using flash as a high-speed non-volatile cache for files on the disk that are often referenced, but rarely modified, such as application and operating system executable files.
